摘要
A transmitter device (103) for sending an encrypted message to a receiver device (105) in an identity-based cryptosystem (100), the transmitter device (103) being associated with a transmitter identifier. The transmitter device (103) is configured to receive a transmitter partial private key from a trusted center (101), the transmitter device (103) being configured to: - send a request for two public session keys to the receiver device (105); - receive from the receiver device (105) a first ciphertext set, the first ciphertext set being derived from an encryption and authentication of two public session keys; - decrypt and authenticate the two public session keys from the first ciphertext set using a receiver identifier and the transmitter partial private key; - determine a second ciphertext set from the transmitter partial private key, from the receiver identifier, and from the two public session keys, the second ciphertext comprising an encrypted message; - send the second ciphertext set to the receiver device (105).
