    摘要: In an encryption apparatus for encrypting a data body to contain an encrypted data body in transmission data and transmitting the transmission data to a receiver, the transmission data includes sender's key recovery data obtained by encrypting recovery information for recovering a key for decrypting the encrypted data body to allow a key recovery agent registered by a sender to decrypt the recovery information, and receiver's key recovery data obtained by encrypting the recovery information for recovering the key for decrypting the encrypted data body to allow a key recovery agent registered by a receiver to decrypt the recovery information.
