## Title
Cryptographically secure dynamic third party resources

## Abstract

A system for providing updatable secure content resource. A content server may pay a content resource on the content author for an access by a requester. The content server receives a session request call from the requester prior to accessing the content resource. In response to the session request, the content server generates a session for the requester. The content server generates a payload that includes a location identifying the content resource on the content author and embeds the embedded cryptographic content. The content server transmits the generated payload to the requester. A resource server may receive an authentication access request in response to the embedded cryptographic content. In response to authenticating the authentication access request, the resource server provides the access to the requester.

## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a continuation of U.S. patent application Ser. No. 16/532,467, filed on Aug. 5, 2019, the entire contents of which are expressly incorporated by reference herein.


TECHNICAL FIELD
Embodiments discussed herein generally relate to providing content security to a third party content authors.
BACKGROUND
Online service providers or hosts provide a variety of services to customers or users. As online providers' web portals or apps for mobile device increase in scale and grow in geographical reach, having a distributed content delivery becomes essential. A content delivery network (CDN) is a system of distributed servers that deliver pages and other web content to users, based on the geographic locations of the users, the origin of the webpage and the content delivery server. This service is effective in speeding the delivery of content of websites with high traffic and websites that have global reach. The closer the CDN server is to the users geographically, the faster the content will be delivered to the users. CDNs may also provide protection from large surges in traffic.
At the same time, CDNs also provide a delivery platform for contents, such as JAVASCRIPT library files. For example, CDNs may host library files to be accessed by users. For example, users may include a Uniform Resource Locator (URL) or a Uniform Resource Identifier (URI) to point to or reference the library files via a web browser. As a part of security measure, web browsers include a Subresource Integrity (SRI) feature, which is a security feature that enables browsers to verify that resources that the web browsers fetch (for example, from a CDN) are delivered without unexpected manipulation. It works by allowing the content authors to provide a cryptographic hash that a fetched resource must match.
This approach, while providing the needed security in the event that the CDN may be attacked or compromised, has a significant drawback. For example, suppose the content authors wish to update the resource (e.g., library files), the content authors would need to create a new URL and provide a new security integrity hash to the updated content. The prior URL, with the prior hash should not be used. However, given the fact that the URL has been previously incorporated into the users' web pages or other applications, the content authors sometimes need to continue to maintain it instead of render the URL invalid or inactive, which may trigger havoc to the users' web pages or other applications.
Therefore, embodiments attempt to create a technical solution to address the deficiencies of the challenges above.
SUMMARY
Embodiments create a technical solution to the above challenges by modifying or updating the existing URL flow. In one embodiment, a new URL flow alters existing or prior use by enforcing an upfront, authenticated request from the integrator to provision a “session” to use the resource. In one example, aspects of embodiments, prior to the use of the resource by a requester, the requester may issue a back-end authenticated call to provision a “session” for the use of the resource. In response to the call, a resource provider or a content author may create a “session,” for the resource usage. Once the session is created, the content author may respond with a payload that includes the URL (host+path) to retrieve the latest version of the script+the SRI value to use when embedding that resource.
The requester may then accept this response to render the fully qualified script tag on their page along with expected SRI for maximum security. The requester may then proceed with their integration as per usual.

DETAILED DESCRIPTION
Embodiments may now be described more fully with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific exemplary embodiments which may be practiced. These illustrations and exemplary embodiments may be presented with the understanding that the present disclosure is an exemplification of the principles of one or more embodiments and may not be intended to limit any one of the embodiments illustrated. Embodiments may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure may be thorough and complete, and may fully convey the scope of embodiments to those skilled in the art. Among other things, the present invention may be embodied as methods, systems, computer readable media, apparatuses, or devices. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment, or an embodiment combining software and hardware aspects. The following detailed description may, therefore, not to be taken in a limiting sense.
Embodiments overcome the challenges of the prior art of having a content author provide various versions of the encrypted content. Aspects of embodiments, alter the existing flow of the secured content provision. Before the access is permitted, the content author may establish a session with the requester. In response to the request for the session, the content server may respond with a payload with a location of the content resource and the authenticated information. The requester may then use the payload by incorporating it to the pages or content linking to the content resource.
Referring now to FIG. 1, a system 100 may provide a secure approach to enable update to content resources. A content author 102, as a third-party provider, may provide a plurality of resources 106 to be used by a requester 104. For example, the plurality of resources may include content resources 106, such as library files (e.g., .DLL files), JAVASCRIPT files (e.g., .js files), etc., for the requester 104. The requester 104 may link or refer to the content resources on a web page. In another example, the content resources 106 may be updated and that the requester 104 may wish to provide to devices such as mobile devices, etc. These devices (not shown) may access a content site 110 that is linked to the resource 106. In one embodiment, the content site 110 may be a web link. In another embodiment, the content site 110 may be a portal accessible from the devices via a software application (e.g., an app) for a mobile device.
For the sake of simplicity, the resource 106 in the following examples may be a JAVASCRIPT file “v1.2.5/lib.js” in a 1.2.5 version. The JAVASCRIPT file may include the needed functions that may be desirable by the requester or integrator 104.
In a further embodiment, the content author 102 may be a cluster of servers that are configured to provide hosting services for contents such that a requester may request access. In yet another embodiment, the content author 102 may be a host server that provides contents as part of a content delivery network (CDN) and provides a resource server 112 for provisioning the resource 106 on request or on demand. The requester 104 may access the resource 106 via a computer executable link (e.g., a uniform resource locator (URL) or a uniform resource identifier (URI)).
To further illustrate aspects of embodiments, referring now to FIG. 2, a system 200 of a prior approach. Typically when attempting to use by a requester 204 for a third party resource 206 hosted by a content author 202, the requester 204 may first locate or identify the resource 206 by visiting or reviewing at 208 a site of the provider 202. The provider 202 would post a link at 212, such as the URL, and the link would include the authentication needed. The requester or the integrator 204 embeds the URL on a content site 210.
In one example, suppose the content author 202 may provide a JAVASCRIPT resource for the requester 204. In such an example, the content author 202 may provide a specific version using the following URL tag:
<script src=“https://example.com/resource/v1.2.5/lib.js”>
</script>
For the latest version:
<script src=“https://example.com/resource/latest/lib.js”>
</script>
To provide further security, the content author 202 may provide an integrity hash to for use with the “specific version” URL:
<script src=“https://example.com/resource/v1.2.5/lib.js” integrity=“sha384-XXXXXXXXXX” crossorigin=“anonymous”></script>
The requester or integrator 204 could then include the URL that points to the content 206 of “lib.js” in building the site or application of the requester or integrator 204.
As explained above, the existing configuration or approach of the system 200 does not permit frequent or convenient way to update to the content 206 when there is a different version to the one to which the URL is directed.
Referring back to FIG. 1, the requester or integrator 104 may not be able to review or identify the URL as in the system 200 as discussed. Instead, the requestor or integrator 104 may first place or send a request 108 to the content author 102. In one embodiment, the request 108 may not be made via a browser. In another embodiment, such request 108 may not be the request placed in the same communication channel as in the system 200 under 208. Rather, according to aspects of embodiments, the request 108 may be a server-to-server call or interaction. In one aspect, the request 108 may be considered as a set-up call or request so that the content author 102 may be noted about what is to be expected later.
In one embodiment, the server-to-server call or interaction may include an application programming interface (API) call between a service account of the requester or the integrator 104 and the server of the content author 102. In one example, such request 108 may not involve a user account of the requester or integrator 104, and may also be known as a “two-legged OAuth,” or “2LO”. In another example, the request 108 may include authentication. For example, the request 108 may include creating and cryptographically sign JSON Web Tokens (JWTs).
However, other authentication measures may be implemented without departing from the spirit and scope of aspects of embodiments. For example, the following authentication measures may be used:
Http Digest; and
Oauth.
Once the service provider 102 receives and processes the request 108, the server at the content author 102 may be configured to respond by creating a session 112. In one embodiment, the session 112 may a traditional type that the content author 102 maintains as part of its application stack. In another embodiment, the session 112 may be an issuing of a signed JSON Web Tokens that contain the payload information mentioned. Other implementations of the session 112 may be incorporated without departing from the spirit and scope of aspects of embodiments.
In one embodiment, the following may further illustrate the session setup or creation according to aspects of embodiments:
In this example, the HTTPS is the protocol used and the authentication used is HTTP Signature—both on request and response.
Http signature on response gives merchant assurance that SRI hash values comes from the payment processor network and may be trusted. When used properly with other security mechanism (e.g. CSP) this enables us to run unmodified code on cardholder devices.
The following example of codes may be implemented as a request from ‘requester’ to ‘content author’:















curl -H ′′Authorization: Bearer SrMCd1aqe6csoHmGnhN7 ′′







http://content.author.com/request/content/links

In one embodiment,
Hash—to provide merchants with SRI information, e.g. requested JS checksum.
Digital signatures (or equivalent) to allow merchants to validate that SRI information provided comes from us.
With the above authentication measures, aspects of embodiments may deliver to merchant the information that allow for rendering HTML page guaranteed to load only content authored by the content author or fail (if malicious content is served).
After creating the session 112, the content author 102 may generate a payload 114 with the requested link to the resource 106 with the needed authentication to be used under the SRI. In one embodiment, after the session created (e.g., via an Authenticated POST message to https://example.com/session), the requester 104 may receive back a payload containing details to use for the integration in the content site 110. In one example under JSON programming, the payload may include:















{









“host”: “https://example.com”,



“path”: “/resource/X49vhxxRg”,



“integrity”: ”sha384-XXXXXXXXXX”









}










In such an example, a first field of the payload may include a location of the content resource 106. For instance, the URL may be “/resource/X49vhxxRg.” In another embodiment, the content author 102 may provide a separate sever 116 to provide the resource 106. For example the server 116 may be a database server or a database store accessible by the content server of the content author 102 to handle such request calls.
In the same example, a second field of the payload may include a security specification. As illustrated above, the security specification may specify that an integrity hash may be a 384 bit value using a secure hash algorithm 2 (SHA-2) function. In one example, the SHA-2 functions may produce other hash values, such as SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256.
After receiving the payload and knowing the requested resource “v1.2.5/lib.js,” the requester or integrator 104 may now embed the latest resource, whilst also setting the correct integrity hash as received from the payload:
<script src=“https://example.com/resource/X49vhxxRg” integrity=“sha384-XXXXXXXXXX” crossorigin=“anonymous”></script>.
Aspects of embodiments provide the host/path information in a format that is conform to the URL in the original example, which further facilitate compatibility and background compatibility using the SRI via a web browser. Alternatively, in another embodiment, the payload may include a fully different URL that may respond with the correct content for the duration of the session created. In one aspect, the integration of the payload in the content site 110 that accesses the resource 106 may take place in a second communication channel (e.g., via the web browser) and not via the same first communication channel (e.g., server-to-server call). For example, the first communication channel differs from the second communication channel.
Furthermore, the content author 102 may also have the ability to dynamically modify the resource content 106 in response to the session parameters. For example the content author 102 may optimize the resource 106 to target a specific user agent engine (minify, polyfils etc.).
Referring now to FIG. 3, a flow chart 300 illustrates a computer-implemented method for provide dynamically modifiable or updatable cryptographically secure third-party resources according to one embodiment. At 302, a content author (e.g., content author 102) may receive a request, via a first channel, from a requester for accessing a content resource. At 304, in response to the request, the content author may generate a session to access the content resource for the requester. At 306, in response to the generated session, the content author further may generate a payload identifying the content resource on a resource provider. In one example, the content author may generate the payload which further embeds a cryptographic content in the payload. In one example, the payload comprises a first data field identifying a location at the resource provider and a second data field for the cryptographic content.
At 308, the content author may transmit the generated payload to the requester. At 310, a resource provider may receive an authentication access request to the content resource, via a second channel, in response to executing the embedded cryptographic content. At 312, the resource provider may, in response to authenticating the authentication access request, provide the requester the access to the content resource.
In another embodiment, the resource provider 116 and the content author 102, while may be shown as separate reference identifiers in FIG. 1, it is to be understood that they may be part of the same cluster of servers providing resources and services to the requester or integrator 104.
FIG. 4 may be a high level illustration of a portable computing device 801 communicating with a remote computing device 841 but the application may be stored and accessed in a variety of ways.

## Claims

1. A computer-implemented method comprising:
providing a content resource by a third-party content provider for an access by a requester;
receiving a request, via a first communication protocol, from the requester for accessing the content resource;
in response to the request, generating a session at the content server to access the content resource for the requester;
in response to the generated session, generating a payload identifying the content resource on a resource provider;
embedding a cryptographic content in the payload, wherein the embedded cryptographic content is accessible via the content server;
transmitting the generated payload to the requester;
receiving an authentication access request to the content resource, via a second communication protocol, wherein the second communication protocol is different from the first communication protocol, in response to executing the embedded cryptographic content; and
in response to authenticating the authentication access request, providing the requester the access to the content resource.

2. The computer-implemented method of claim 1, wherein the session comprises a server-to-server request call.

3. The computer-implemented method of claim 1, wherein the payload comprises a first data field identifying a location at the resource provider and a second data field for the cryptographic content.

4. The computer-implemented method of claim 1, wherein the content resource comprises computer software library executable files.

5. The computer-implemented method of claim 1, wherein the session comprises a timed application stack or a web token.

6. The computer-implemented method of claim 3, wherein the location comprises a uniform resource locator (URL) or a uniform resource identifier (URI).

7. The computer-implemented method of claim 1, wherein the second communication protocol comprises a subresource integrity (SRI) via a web browser.

8. A computer-implemented method comprising:
receiving a request, via a first communication protocol, from a requester for accessing a content resource;
in response to the request, generating a session at the content server to access the content resource for the requester;
in response to the generated session, generating a payload identifying the content resource on a resource provider;
embedding a cryptographic content in the payload, wherein the embedded cryptographic content is accessible via the content server;
transmitting the generated payload to the requester;
receiving an authentication access request to the content resource, via a second communication protocol, wherein the second communication protocol is different from the first communication protocol, in response to executing the embedded cryptographic content; and
in response to authenticating the authentication access request, providing the requester the access to the content resource.

9. The computer-implemented method of claim 8, wherein the session comprises a server-to-server request call.

10. The computer-implemented method of claim 8, wherein the payload comprises a first data field identifying a location at the resource provider and a second data field for the cryptographic content.

11. The computer-implemented method of claim 8, wherein the content resource comprises computer software library executable files.

12. The computer-implemented method of claim 8, wherein the session comprises a timed application stack or a web token.

13. The computer-implemented method of claim 10, wherein the location comprises a uniform resource locator (URL) or a uniform resource identifier (URI).

14. The computer-implemented method of claim 8, wherein the second communication protocol comprises a subresource integrity (SRI) via a web browser.

15. A system comprising:
a content server configured to receive a request, via a first communication protocol, from a requester for accessing a content resource;
in response to the request, the content server is configured to generate a session at the content server to access the content resource for the requester;
in response to the generated session, the content server is configured to generate a payload identifying the content resource on a resource server;
embedding a cryptographic content in the payload, wherein the embedded cryptographic content is accessible via the content server;
wherein the content server is configured to transmit the generated payload to the requester;
wherein the resource server is configured to receive an authentication access request, via a second communication protocol, wherein the second communication protocol is different from the first communication protocol, in response to executing the identified cryptographic content; and
in response to authenticating the authentication access request, the resource server is configured to provide the requester the access to the content resource.

16. The system of claim 15, wherein the session comprises a server-to-server request call.

17. The system of claim 15, wherein the payload comprises a first data field identifying a location at the resource provider and a second data field for the cryptographic content.

18. The system of claim 15, wherein the session comprises a timed application stack or a web token.
