ABSTRACT:
A relay apparatus comprises a frame relay processing unit for relaying a frame, a plurality of ports for sending and receiving the frame to and from the outside, and a cryptographic processing module corresponding to each of the ports. Each cryptographic processing module is connected to the corresponding port and to the frame relay processing unit by means of general-purpose interfaces such as MII. The cryptographic processing module performs the encryption process and decryption process so that the frame relay processing unit can concentrate on the relay process and the relay speed is not subject to degradation. Also, the cryptographic processing module can generate a different cryptographic key for each frame without requiring dynamic exchange of key information.
