Abstract: A secure and efficient handover authentication protocol is highly desirable in mobile wireless networks. In this paper, we propose an efficient handover authentication scheme using the (ID) identity-based signcryption technique. The ID-based cryptosystems have found wide applications in mobile wireless networks for their ellipsis of the verification of public keys and the transmission of associated certificates. Different from traditional signature-then-encryption approach, the signcryption technique can considerably reduce the computation cost by enabling a sender to sign and encrypt data in a single operation. Based on the above cryptographical techniques, only four point multiplications need to be calculated on a resource-constrained mobile node during the handover process. In addition, security analysis demonstrates that our scheme achieves the location privacy-preserving for mobile users and perfect forward/backward secrecy.
