Abstract

A cryptographic apparatus has an encryption/encapsulation processing section for encrypting plaintext data received from a plaintext network, referencing the predetermined correspondence between addresses and different cryptographic apparatus, setting a new header based on the cryptographic apparatus corresponding to the address set in the header of the plaintext data as encapsulation processing, and transmitting ciphertext data provided thereby to the ciphertext network of the same IP subnet as the plaintext network, and a decryption/decapsulation processing section for decrypting ciphertext data received from the ciphertext network into plaintext data, again setting a header based on the address set in the header of the plaintext data as decapsulation processing, and transmitting plaintext data provided thereby to the plaintext network of the same IP subnet as the ciphertext network.
