Abstract:
A method for securely receiving a cipher key from a key provider to a key requester is provided. The method includes generating a session key shared between the key requester and the key provider, determining at least one key in accordance with the session key. The method also includes transmitting a request from the key requester to the key provider, and receiving a response from the key provider, where the response comprises an encrypted payload and an authentication tag. The method also includes authenticating the response and decrypting the encrypted payload using the at least one key to obtain the cipher key.
