摘　　要：针对电子商务中电子现金支付的安全性问题,提出了一种基于对称加密和Hash函数的轻量级安全支付方案。买家在银行端进行注册,并获得智能卡后,在支付阶段,利用对称加密保证数据完整性,利用Hash函数保证数据前向安全性,以此实现对买家、银行端和卖家之间的相互认证。银行端对交易信息进行验证并存储,保证信息的不可否认性。性能分析表明,该方案能够抵御多种安全性攻击,并具有较低的计算复杂度。For the issue of the security problem of electronic cash payment in e-commerce, a lightweight security payment scheme based on symmetric encryption and Hash function is proposed. First, the buyer registers in the bank, and accesses his smart card. Then, in the payment stage, the symmetric encryption is used to ensure data integrity, and the Hash function is used to ensure the data forward security, in order to achieve the mutual authentication among the buyer, the bank and the sell- er. Finally, the transaction information is verified and stored by bank terminal, to ensure that the information does notbe de- nied. Performance analysis shows that the proposed scheme can resist many kinds of security attacks, and has low computation- al complexity.
