Enhanced Remote Authentication System Based On Certificateless Cryptography in Wireless Body Area Network
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 10
Abstract
As a subgroup of Wireless sensor network, Wireless Body Area Network (WBAN) has been recognized as one of the emerging techniques for improving the healthcare service. However the security and privacy of user’s physiological information remains a major concern. Even though many remote anonymous authentication protocols have been proposed, it raises challenges such as forward security and scalability. This paper proposes a new certificateless remote anonymous authentication protocol that efficiently addresses the above challenges. Apart from the security requirements provided by the existing protocols it also achieves forward security, scalability and inherent key escrow. Our protocol ensures that even the network manager which serves as a key generating centre cannot impersonate the legitimate users. Performance evaluation demonstrates that the proposed authentication protocol outperforms all the other existing schemes in terms of computational cost.
