Secured cryptographic communication system

摘要

According to an embodiment, a communication apparatus includes a finding unit; a negotiating unit; and a communicating unit. The finding unit is configured to, in response to a request from an application that makes use of key information, find out a key generating device that generates the key information. The negotiating unit is configured to perform a negotiation operation with respect to the key generating device to determine conditions for key information that is to be generated. The communicating unit is configured to receive, from the key generating device, the key information that is generated based on the conditions determined in the negotiation operation, and send the received key information to the application.

1. A communication apparatus comprising:
a finding unit configured to, in response to a request from an application that makes use of key information, find out a key generating device that generates the key information by generating and sharing a random number with another key generating device; a negotiating unit configured to perform a negotiation operation with respect to the key generating device to determine conditions for key information that is to be generated, the conditions including throughput indicating a bit length of key information usable per unit time by the application among the key information generated by the key generating device; and a communicating unit configured to receive, from the key generating device, the key information that is generated based on the conditions determined in the negotiation operation, and send the received key information to the application; a verifying unit verifies the presence or absence of a security function applicable to communication between the apparatus and the key generating device, and if the security function is present, the verifying unit determines that the verification is successful.
