Authentication scheme for smart card remote payment system based on mutual authentication and 3 DES encryption
摘要
Abstract
For the issues that the present smart card remote payment system security scheme existing password exposure,in-formation leakage and authentication,this paper proposed an authentication scheme for smart card remote payment system based on mutual authentication and information encryption.It analysed the defects of existing payment authentication scheme based on quadratic residue and improved those defects in registration,login,identity authentication and password change phase,to avoid attack of cryptographic exposure and improve the safety of password change phase.At the same time,it com-bined with 3DES encryption algorithm to encrypt the payment information.The performance analysis shows that the scheme can resist many kinds of attacks effectively,and allow the users to change their passwords freely,meanwhile,providing anonymous protection of user information.Compared with the existing smart card authentication scheme,this scheme improves the security performance of card remote payment system and has a smaller computational complexity.关键词
