Two-factor wearable device authentication protocol based on PUF and IPI
Published 2017-06-01“…Wearable device is pushing the rapid development of mobile health,however,the open architecture of wireless body area network has brought challenges for the security of user data.In order to protect the security of user data,a two-factor authentication protocol between device note and data hub was proposed based on physically unclonable function and interpulse interval.Using dual uniqueness of device physical characteristic and user biometric trait,the protocol can resist compromise and impersonation attacks and was specially suitable for resource constrained wearable devices under body area network.Compared with the existing authentication schemes,the security of the proposed protocol was enhanced.The practicability and effectiveness of the protocol are confirmed by hardware implementation on FPGA.…”

Provably secure certificateless aggregate signature scheme in wireless roaming authentication
Published 2017-07-01“…Certificateless aggregate signature (CLAS) schemes have been widely applied in resource-constrained wireless mobile networks,because they could not only realize batch validation but also solve the certificate management and key escrow problems.It was shown that a certificateless aggregate signature in an anonymous roaming authentication scheme was vulnerable to the signature forge attack.To address the issue,a new secure and efficient certificateless aggregate signature scheme was presented,which required no bilinear pairing operations.And then the security of the scheme under the ECDLP assumption in the random oracle model was proved.Finally the performance of proposed scheme was evaluated.Compared with the original scheme,the proposal is more secure and the total computational cost is greatly reduced .…”
