Abstract
A method implemented by computers includes exchanging a key between a first user and a second user. Ephemeral session keys are generated. The ephemeral session keys are generated by a first computer associated with the first user and a second computer associated with the second user. An encrypted key generation response is exchanged between the first computer and the second computer. A new session request is received. It is determined that there is a valid session state. It is confirmed that there is a valid user. It is determined that there is a valid session identification. Information between the first computer and the second computer is cryptographically exchanged in response to the valid session state, the valid user and the valid session identification.
