Patent application EP18156554A (EP), filed 2018-02-13
Publication number: EP3396922A1
Title: INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING SYSTEM AND INFORMATION PROCESSING METHOD
Abstract: According to an embodiment, an information processing apparatus includes a storage controller(32G;36G). The storage controller (32G; 36G) is configured to store, in a storage, communication data of nodes connected via a network and authentication information that is used for authentication between the nodes in communication of the communication data so that the communication data and the authentication information are associated with each other.

Claims: number: 1
text: An information processing apparatus comprising:
number: 2
text: The information processing apparatus according to claim 1, wherein the authentication information is a message authentication code, a random number, a counter value, or a digital signature.
number: 3
text: The information processing apparatus according to claim 1 or 2, wherein the storage controller(32G;36G) stores, in the storage, address information indicating a region in which the communication data and the authentication information are subsequently stored at the time of termination and stores the communication data and the authentication information in the region indicated by the address information that is read from the storage at the time of activation.
number: 4
text: An information processing apparatus comprising:
number: 5
text: The information processing apparatus according to claim 4, further comprising a verifier(32D) configured to verify the authentication information, wherein
the derivation unit(36K) derives, as the transmission source information, verification identification information for identifying information used for verifying the authentication information when a verification result by the verifier(32D) indicates that verification is successful, and
the derivation unit(36K) derives, as the transmission source information, verification abnormality information when the verification result indicates that verification is unsuccessful.
number: 6
text: The information processing apparatus according to claim 5, wherein the authentication information is a message authentication code and the verification identification information is index information of a common key used for generation and verification of the message authentication code.
number: 7
text: The information processing apparatus according to claim 5, wherein the authentication information is a random number and the verification identification information is index information of a pseudo random number generator for generating the random number.
number: 8
text: The information processing apparatus according to claim 5, wherein the authentication information is a count value and the verification identification information is index information of a counter for generating the count value.
number: 9
text: The information processing apparatus according to claim 5, wherein the authentication information is a digital signature and the verification identification information is a public key certificate used for generation of the digital signature.
number: 10
text: The information processing apparatus according to any one of claims 4 to 9, wherein the storage controller(32G;36G) stores, in the storage, address information indicating a region in which the communication data and the authentication information are subsequently stored at the time of termination and stores the communication data and the authentication information in the region indicated by the address information that is read from the storage at the time of activation.
number: 11
text: The information processing apparatus according to any one of claims 5 to 9, wherein the verifier(32D) stores, in the storage, information used for verifying the authentication information at the time of termination and verifies the authentication information using the information that is read from the storage at the time of activation.
number: 12
text: An information processing system comprising:
number: 13
text: An information processing method comprising storing, in a storage(34;38), communication data of nodes connected via a network and authentication information that is used for authentication between the nodes in communication of the communication data so that the communication data and the authentication information are associated with each other.
