The first record part 34 e uses, as its protocol data format, the same format as that of the SSL record part shown in FIG. 6. The handshake part 34 a negotiates with the receiving-side communication apparatus 40 about the encryption/data authentication parameters that are used in the first record part 34 b and the second record part (encryption/authenticator adding part) 33. And the change cipher (Change Cipher) part 34 b validates the encryption/data authentication parameters of the first record part 34 e and the second record part 33. That is, it starts and indicates encryption to the receiving side. To the first record application data part 34 e are input a protocol message of the handshake part 34 a and application data that does not necessitate the selective encryption in the first application data part 34 d.
The transmission and reception of application data that necessitates selective encryption are performed, independently of the above-mentioned protocol data, by a second record part, that is, by the encryption/authenticator adding part 33. A second application data 37 is to transparently send and receive the data packet of a high-order second application part 31 b to and from the second record part 33. Further, unlike the first record part 34 e the second record part, that is, the encryption/authenticator adding part 33 does not add a new header to the input data but performs the encryption/authenticator generation processing alone. The parameters shared by the first record part 34 e are used for the encryption/data authentication processing in the second record part 33. The encryption/data authentication processing is the same as in the first embodiment.
