Detailed Description

This is a short-lived server that runs the protocol to establish a connecting server's identity.

The protocol is a simple challenge-response, with this local server denoted L and the remote server R.

L selects a random nonce n and sends it to R.
R composes a message containing its name and n, which it signs and returns to L. Including the nonce prevents replay attacks.

InternalVerifier::InternalVerifier ( int port,

const CODEX_Quorum::SocketBuilder & socketBuilder,

CODEX_Quorum::SocketBase * socket

)

Constructor.

Parameters:

port The port on which to listen.

socketBuilder Not used, but required by base class.

socket An already-configured socket for the connection.

void InternalVerifier::processRequest ( CODEX_Quorum::SocketBase::StateType s ) [virtual]

Process incoming requests.
Derived classes must implement this routine, which is called whenever a connection is made.

Attention:
No further connections may be handled, nor any other actions taken, until this function returns. Consequently, if you do not want your program to block on a request, you must implement some concurrency mechanism, such as an event model or threads. This class makes no assumptions about concurrency.

Implements CODEX_Quorum::LocalServer.
