Abstract:

   This document specifies the State Graph Cryptographic Protocol
   (SGCP), a communication-security framework in which a client and
   server establish a cryptographically protected session and maintain
   a synchronized state graph throughout the lifetime of the
   communication session.

   SGCP combines device identity, port context, socket context,
   session identity, ECDH-based shared-secret establishment,
   cryptographic key derivation, epochs, packet sequence numbers,
   authenticated state transitions, state-dependent packet
   transformation, replay protection, continuous context verification,
   controlled reauthentication, and session recovery.

   The central principle is that both endpoints independently derive
   the same cryptographic state from a common authenticated session
   secret and deterministic state information.  The state graph
   defines which communication states are valid and which transitions
   are permitted.

   This document also illustrates the protocol with a worked example
   of a full-duplex binary media file transfer (an MP3 audio file)
   showing the complete packet-level exchange.
