Identity-based Handover Authentication Scheme without Pairing or Wireless Networks

Handover authentication scheme for mobile network enables mobile nodes to roam safely on different access points. Recently, a handover authentication protocol called pairhand and its improved scheme have been proposed, which are superior to all other schemes in security and efficiency. However, both schemes are based on bilinear pairings, which is a complex operation. In this paper, a novel pair-less handover authentication protocol is proposed. It eliminates the pairing operations, and further reduces the computation cost on mobile user without losing any security features.
