A message processing request is received from a channel partner device, where the message processing request includes a ciphertext message encrypted in a trusted execution environment (TEE) of a service provider device based on a service processing request that includes a plaintext message of the ciphertext message, and where the service processing request requests at least a portion of the plaintext message to be sent to a target user. A first smart contract deployed in a blockchain of the blockchain network is invoked using a TEE of a blockchain node of a blockchain network. The ciphertext message is decrypted based on the first smart contract to obtain the plaintext message. The plaintext message is sent to an operator device to forward the at least a portion of the plaintext message to the target user.
