摘　　要：移动代理的安全问题是移动代理技术面临的一个很大障碍.为保护移动代理支付时的信息安全,采用Pedersen可验证秘密分享方案,设计了一个基于移动代理技术的安全支付协议.文中详细分析和讨论了协议的性能,包括安全性、不可否认性以及协议的运行效率.结果表明,和已有的方案相比,该协议在保证具有合适运行效率的同时,弱化了已有方案的安全执行条件,增加了系统的安全性和灵活性,因此具有更好的应用价值.The security of mobile agent is an obstacle that has to be faced in mobile agent technology. In order to protect the information confidentiality in the payments using mobile agents, this paper presents a secure payment protocol based on mobile agents by adopting the verifiable secret sharing scheme of Pedersen. Moreover, the performances of the proposed protocol, including the security, the non-repudiation and the running efficiency, are analyzed and discussed in detail. The results show that, compared with the existing methods, the proposed protocol is more practically valuable because it ensures the security of payment information with ease while possessing a suitable running efficiency, and improves the security and flexibility of the payment system.
