Abstract
A method of managing secure communications states in an endpoint within a secure network is disclosed. The method includes, in a disconnected state, transmitting from a first endpoint to a second endpoint a first message including an authorization token. The method further includes, in the pending state, receiving from the second endpoint a second message including a second authorization token at the first endpoint. The method includes, based on the receipt of the second message, entering an open state and initializing a tunnel between the first and second endpoints using an IPsec-based secured connection. The method also includes, upon termination of the tunnel due to a termination or timeout message issued by at least one of the first and second endpoints, entering a closed state.
