【摘要】：近年来随着移动通信的高速发展,以及移动智能终端设备的快速普及,电子商务活动逐渐进入移动电子商务时代,移动支付迎来了飞速发展的时期,在许多国家得到了快速的普及和部署。 安全协议作为移动支付的重要环节,是移动支付实现安全运行和走向广泛应用的重要保证。同时由于无线网络资源受限,亟需轻量级和安全性能较好的移动支付安全协议,但目前仍没有非常合适的解决方案。本文的工作重点就是如何设计一种轻量级和安全性能好的安全协议,所取得的具体研究成果如下： (1)分析了SET, iKP等几种常用的基于公钥体制的电子支付安全协议的安全性能,给出了基于公钥体制的安全协议的不足； (2)针对上述移动支付安全协议的不足,提出了一种改进的基于对称密钥的安全支付协议,该协议在执行过程中减少了密码操作的数量,因而较已有协议能提供更好的有效性。安全性分析表明,该协议具有比较好的安全性
[Abstract]:In recent years, with the rapid development of mobile communication and the rapid popularization of mobile intelligent terminal devices, e-commerce activities have gradually entered the era of mobile e-commerce, mobile payment has ushered in a period of rapid development. In many countries, it has been rapidly popularized and deployed. As an important link of mobile payment, security protocol is an important guarantee for mobile payment to realize safe operation and wide application. At the same time, due to the limitation of wireless network resources, there is an urgent need for a lightweight and secure mobile payment security protocol, but there is still no very suitable solution. The focus of this paper is how to design a lightweight and secure security protocol. The specific research results are as follows: (1) SET, is analyzed. The security performance of several common electronic payment security protocols based on public key system, such as iKP, is given, and the shortcomings of public key based security protocols are given. (2) an improved secure payment protocol based on symmetric key is proposed, which reduces the number of cryptographic operations in the execution process. Therefore, it can provide better validity than the existing protocol. The security analysis shows that the protocol has good security.
