Clio Authentication System

gistfile1.txt

Given two nodes, Bob and Amy, Bob initiates a connection and authentication with Amy.

Bob sends a packet (id 1) containing json serialized data of:
{
    "ID": 1,
    "PublicKey": (Bobs public key),
    "NetworkHash": A 32 bit string representing the network ID Bob is on,
    "Token": a 32-bit random integer
}

If Amy decides its worth authenticating with Bob (e.g. network id is correct, and the public key is valid) then Amy sends an auth packet (id 2) back containing json serialized data of:
{
    "ID": 2,
    "PublicKey": (Amys public key),
    "Payload": Encrypted and Signed PGP data for Bob, signed with the key above, data is:
        {
            "T1": The token from Bob's inital packet,
            "T2": a new random token
        }
}

At this stage, Bob and Amy have completed the handshake and are besties 5ever. They now can communicate in an encrypted and trust-based fashion. At any time, either can decide to provide a new token to use for authentication (by default every subsequent packet provides a new token)

Packet encryption works based off HMAC: FILL ME IN!
