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。
Aiming at the security problem of e-cash payment in e-commerce, a lightweight secure payment scheme based on symmetric encryption and Hash function is proposed. After registering on the bank side and obtaining a smart card, the buyer uses symmetric encryption to ensure data integrity during the payment phase and uses Hash function to ensure the forward data security, so as to realize mutual benefit to buyers, banks and sellers Certification. Bank side of the transaction information to verify and store, to ensure the non-repudiation of the information. Performance analysis shows that the scheme can resist multiple security attacks and has lower computational complexity.
