Remote password authentication with smart cards
Chin-Chen Chang,Tzong-Chen Wu +1 more
TL;DR: A remote password authentication scheme based on the Chinese remainder theorem is proposed that can verify the remote password without verification tables and provide a signature scheme and communication timestamps in the authentication phase against the potential attacks of replaying a previously intercepted login request.
Journal ArticleDOI
Two RFID-based Solutions to Enhance Inpatient Medication Safety
TL;DR: The weaknesses of the Huang–Ku scheme are shown, and two RFID-based solutions to enhance medication safety for two different scenarios are proposed, which are practical, secure and efficient for medication applications.
Journal ArticleDOI
New nonrepudiable threshold proxy signature scheme with known signers
TL;DR: A new nonrepudiable threshold proxy signature scheme is proposed that overcomes the above weakness and is more efficient than Sun's in terms of computational complexities and communication costs.
Proceedings ArticleDOI
GAnGS: gather, authenticate 'n group securely
Chia-Hsin Owen Chen,Chung-Wei Chen,Cynthia Kuo,Yan-Hao Lai,Jonathan M. McCune,Ahren Studer,Adrian Perrig,Bo-Yin Yang,Tzong-Chen Wu +8 more
TL;DR: GAnGS, a protocol for the secure exchange of authenticated information among a group of people, is proposed and designed to be robust to user errors, such as miscounting the number of participants or incorrectly comparing checksums.
Journal ArticleDOI
New dynamic ID authentication scheme using smart cards
TL;DR: It is demonstrated that both of the proposed schemes cannot achieve the security requirement for user anonymity and resist an impersonation attack yet, and a new dynamic ID authentication scheme is proposed to overcome the above security weaknesses.
