AB  - In this paper, we propose EM3 A, a novel scheme that guarantees the authenticity of a mobile node (MN) and a relay node (RN) in a multi-hop-enabled Proxy Mobile IP (PMIP) network. EM3 A works in conjunction with a proposed scheme for key establishment, based on symmetric polynomials, to generate a shared secret key between MN and RN. This scheme achieves lower revocation overhead than that achieved by existing symmetric polynomial-based schemes. For a PMIP domain with n points of attachment, EM 3 A achieves t×2n-secrecy, whereas the existing authentication schemes achieve only t-secrecy. Computation and communication overhead analysis, as well as simulation results, demonstrate that EM 3 A achieves low authentication delay and is suitable for seamless multi-hop IP communications. © 2012 IEEE.
