摘要
无线通讯技术的进步和市场的广大使得在移动环境中进行商务活动广受关注,而数字时间戳技术是保障安全的重要措施之一。考虑到目前移动环境下数据通信的一些限制,主要是移动终端有限的能力和无线传输有限的带宽,分析比较了现有的几种时间戳协议(线性链接协议,分布式信任协议和树型链接协议)在移动环境中的应用,并引入WPKI实现移动环境中的数字时间戳服务。
Technology evolution in wireless communication and the growing market make M-commerce get emerging attention. And the digital time-stamping is one of the important solutions providing security services. Considering the limit of mobile environment including the limited power of mobile device and the limited bandwidth of wireless communication, the applications of several time-stamp protocols are compared and analyzed （for example, linear linking scheme, distributed trust scheme and tree like linking scheme） in mobile environment, and WPKI is imported to provide digital time stamping services in mobile environment.
