Confidential communication management

Abstract:

Systems and methods are provided for confidential communication management. For example, a client computer can determine a client key pair comprising a client private key and a client public key. The client computer can further determine a protected server key identifier, identify a server public key associated with the protected server key identifier, and generating a shared secret using the server public key and the client private key. The client computer can further encrypt message data using the shared secret and sending, to a server computer, a message including the encrypted message data, the protected server key identifier, and the client public key. The protected server key identifier can be associated with the server computer and can be usable by the server computer to identify a server private key to be used in decrypting the encrypted message data.
