Agent System POND 1.0 (1.7.2000)

Class ServingThread


class ServingThread
extends CancellableThread

A thread to receive an agent from a remote host. It is verified in advance, whether the agent is allowed to move here. If AgentSystem.SECURE_CONNECTION is true, Diffie-Hellman key exchange is used to encrypt the communication. Then also the identity of the remote host is verfied (challenged for knowledge of the private key). This verification is symmetric: We also have to prove our identity. Both hosts must have the same value, else the protocol will be aborted. (AMP = Agent Movement Protocol)
