Abstract
Methods and systems for secure communications are provided. Secure end-to-end connections are established as separate multiple secure connections, illustratively between a first system and an intermediate system and between a second system and an intermediate system. The multiple secure connections may be bound, by binding Internet Protocol Security Protocol (IPSec) Security Associations (SAs) for the multiple connections, for example, to establish the end-to-end connection. In the event of a change in operating conditions which would normally require the entire secure connection to be re-established, only one of the multiple secure connections which form the end-to-end connection is re-established. Separation of end-to-end connections in this manner may reduce processing resource requirements and latency normally associated with re-establishing secure connections.
