Provably secure and pairing-free identity-based handover authentication protocol for wireless mobile networks

摘要

This study presented an efficient design of identity-based handover authentication protocol for wireless mobile networks under the prime-order elliptic curve cryptosystem. The present work does not include the time-consuming and expensive bilinear pairing and map-to-point hash functions. The proposed protocol is analyzed in the random oracle model and also demonstrated to have other security properties, including protection against replay attack and denial-of-service attack, user anonymity and unlinkability, subscription validation, conditional privacy preservation, and mutual authentication. Our handover authentication protocol is examined to be more efficient from the size of the security parameter and computation costs than the previous protocols.
