摘要
Abstract
Electronic commerce is widely used now,and the resent research focus on the efficiency and security of electronic commerce protocols.A countable and time-bound password-based user authentication scheme for the electronic commerce promoted by Iuon-Chang Lin and Chin-Chen Chang is discussed.User＇s password of the protocols is based on the hard problem modular square root.However,there＇s a bug in this scheme,and the efficiency of the scheme is low.A new scheme based upon Hash chain is advanced,and its security is discussed.The new scheme has solved the bug in the original scheme,and it is more efficient and safer.关键词
