Abstract
A plurality of devices are each operable to provide information that is usable for to prove authorization with any of the other devices. The devices may have common access to a cryptographic key. A device may use the cryptographic key to encrypt a session key and provide both the session key and the encrypted session key. Requests to any of the devices can include the encrypted session key and a digital signature generated using the session key. In this manner, a device that receives the request can decrypt the session key and use the decrypted session key to verify the digital signature.
