ABSTRACT:
A transmission apparatus 100 includes a secret key storage unit 103 that stores three secret keys K1, K2 and K3, a secret key selection unit 104 that selects one secret key Ks from the secret keys, a message generation unit 106 for generating a message M used as a carrier for indicating a secret key, an encryption module 105 for generating a cryptogram Ca by encrypting the generated message M using the secret key Ks, an encryption module 107 for generating a cryptogram Cm by encrypting the message M using the message M itself as the secret key, and two transmission units 111 and 112 for transmitting the cryptograms Ca and Cm to the reception apparatus 200 to indicate the selected secret key Ks. The reception apparatus 200 includes a decryption module, such as 221, for generating decrypted data Mi by decrypting the cryptogram Ca using a secret key Ki out of the three secret keys, and a decryption module, such as 222, for generating decrypted data Mii by decrypting the cryptogram Cm using the decrypted data Mi, and authorizes that the secret key Ki has been selected when the decrypted data Mi matches the decrypted data Mii.
