MESP: A Multicast Framework for the IPsec ESP
Multicast ESP (MESP) is a framework for multicast data-origin authentication using the IPsec Encapsulating Security Payload (ESP) protocol. The MESP framework combines group-secrecy, group- authentication, and source-authentication transforms in an ESP packet. MESP uses a message authentication code for group authentication to protect a digital signature, TESLA timed MAC, or other multicast source-authentication transform.
