Abstract
Systems, methods and computer program products for sharing state information between a stateless server and a stateful client are provided. A client request to perform an action on the server is accompanied by an encrypted token which contains state information. The server receiving the client request decrypts the token using a symmetric key generated from variable data. The server verifies that the received token is valid and uses the state information contained therein to perform the requested action. The server also provides clients with encrypted tokens using a symmetric key generated from variable data.
