Abstract:
1. A network system providing integration, comprising: a remote access switch providing an interface between a client computer and a server, wherein all communications between the client computer and the server are transmitted via the remote access switch; a client-side cryptographic function providing cryptographic services located on the client computer; a server-side cryptographic function providing cryptographic services located on the server; the client computer, configured to dial into the remote access switch, comprising: the server, configured to connect to the remote access switch via a wide area network, comprising: wherein the PKI-Bridge is configured to check version information of a client computer and send an identification to the server-side cryptographic function, wherein the server-side cryptographic function is configured to generate a challenge string in response to the identification, wherein the client-side cryptographic function is configured to generate a signed response string in response to the challenge string, wherein the custom script dynamically linked library is configured to encode and divide the signed response string to obtain a plurality of packets, wherein the PKI-Bridge is configured to combine and decode the plurality of packets to obtain a reconstructed signed response string, wherein the server-side cryptographic function is configured to verify the reconstructed signed response string to generate a result, and wherein the server-side cryptographic function is configured to send an instruction based on the result to the server via the PKI-Bridge, wherein the instruction specifies whether the server should send an allow connection message to the remote access switch.
