摘　　要：在身份认证领域,动态口令技术由于其良好的安全性和操作的简易性,越来越受到用户的信任和青睐。国内现有的动态口令产品普遍采用国外的SHA系列算法,对信息安全的本土化造成潜在的威胁。实现国有密码算法自主技术产品的研发,将使密码产品的安全性得到更好的保障。选用基于时间同步的动态口令认证技术,采用国有密码SM3算法,完成了一种动态口令卡的设计和实现。通过仿真实验与测试表明,该卡达到了降低功耗,增强动态口令安全性的设计要求,具有较强的应用价值。Due to its excellent security and simplicity in operation,dynamic password technique has own the trust and favour by increasing customers in identity authentication realm.Existing domestic dynamic password products generally adopt foreign SHA series algorithm,which is a potential menace to the localisation of information security.To realise independent development of technical products of state-owned cryptographic algorithms will better safeguard the security of cryptographic products.This paper presents the design and implementation of a dynamic password card,which adopts time synchronisation-based technique in dynamic password authentication and uses state-owned SM3 cryptographic algorithm.With simulative experiments and test,it is demonstrated that our implementation achieves the design target of low power dissipation and the enhanced high security in password,and is of high applied value.
