A novel anonymous authentication scheme without cryptography
Runhua Shi, Hong Zhong, Liusheng Huang · Transactions on Emerging Telecommunications Technologies · 2012
ABSTRACT In this paper, we present a novel anonymous authentication scheme without employing any symmetric or asymmetric cryptosystem. The security of our scheme is guaranteed by the basic theories for solving linear equations, which can ensure it is unconditionally secure. The proposed scheme is adaptable for resource‐constrained devices or wireless networks well, because it only needs to perform several scalar multiplications instead of complex cryptographic operations and takes only one round of message exchange (challenge–response) between the verification centre and the legal user.
