修正的HARQ加密方案第三方支付系统安全设计

Design of Third Party Payment System Safety Protection Based on Modified HARQ Encryption Scheme

引入云计算的虚拟化技术,提出一种修正的HARQ加密方案,利用群签名和椭圆曲线算法ECC提高加密协议的执行效率,根据上行CSI信息对重传分组自适应地选择冗余版本数,结合云计算的虚拟化技术建立一种基于修正的HARQ加密方案的可信云平台第三方支付方案,嵌入设计到第三方支付系统中,最后对方案的安全性和效率进行分析。仿真实验表明,采用该算法进行第三方支付信息加密和支付系统嵌入设计,能够提供安全稳定的隐私保护和远程证明,支付平台通信效率提高,安全保护性较强。能有效促进电子商务产业的安全发展。

The virtualization technology in cloud computing is used, this paper proposes a modified HARQ encryption scheme, and improve the encryption efficiency of the implementation of the protocol by using group signature and elliptic curve algorithm ECC. According to the information of uplink CSI retransmission packet adaptively selecting redundancy version number, combined with virtualization technology in cloud computing to establish a trusted third party encrypted cloud platform scheme based on the modified HARQ payment scheme. The third party payment system is designed. The safety and efficiency of the scheme analysis are taken. Simulation results show that, by new method can provide privacy pro-tection security and remote attestation, and the payment platform communication efficiency is improved with strong safety protection. It can effectively promote the safety of electronic commerce industry.
