FIELD: computer equipment.
SUBSTANCE: invention relates to confidential communication control. For example, the server computer may contain a secure identifier of the server key in the response message for the client computer. Protected identifier of the server key may contain an identifier of the server key which identifies the server private key used to encrypt the response message. Client computer can transfer protected server key back in subsequent request so, that the server computer can identify the proper server private key for use in order to decrypt the message with the request. In another example, the message may contain encrypted protocol data (e.g., a set of ciphers) and separately encrypted payload data. Encrypted payload data may comprise a plurality of separately encrypted payload elements.
EFFECT: technical result is improved communication security.
