Abstract
According to an embodiment, a communication apparatus includes a key storage unit configured to store therein a cryptographic key; a receiving unit configured to receive a message; an analyzing unit configured to analyze whether the message includes an access request for the cryptographic key; a generating unit configured to, when the message includes the access request, generate request information used to request an access to the cryptographic key requested by the access request; and an access controller configured to control the access to the cryptographic key based on the request information.
Claims7
A communication apparatus comprising:
- a key storage unit configured to store therein a cryptographic key;
- a receiving unit configured to receive a message;
- an analyzing unit configured to analyze whether the message includes an access request for the cryptographic key;
- a generating unit configured to, when the message includes the access request, generate request information used to request an access to the cryptographic key requested by the access request;
- and
- an access controller configured to control the access to the cryptographic key based on the request information.
A key managing method which is performed by a communication apparatus including a key storage unit that stores therein a cryptographic key, the method comprising:
- receiving a message;
- analyzing whether the message includes an access request for the cryptographic key;
- generating, when the message includes the access request, request information used to request an access to the cryptographic key requested by the access request;
- and
- controlling the access to the cryptographic key based on the request information.
