摘要： 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.

摘要： Asymmetric key generation apparatus generates asymmetric key based on a different key material for each piece of data. The symmetric key generation apparatus is configured to generate a symmetric key of a practically different value for a key material of a different value. An encrypted piece of data has a part encrypted by a symmetric key and a part of a cleartext. The latter part includes a key material used by the symmetric key generation apparatus that uses it for generating a symmetric key.

摘要： The extra length accommodation structure for the optical fiber includes a base and first and second winding drums pivotably supported to the base. Each of the first and second winding drums is pivotable between a position where it is positioned over the base and another position where it is partially projected from the base. The first winding drum is pivotably supported through a first support member to the base, and the second winding drum is pivotably supported through a second support member to the base.
