摘要
固网支付是中国电信与中国银联合作推出的一项固网短消息增值业务,需要较高的安全级别。为了在兼容现行固网支付安全方案并扩充业务的同时提高系统的安全强度,实现动态密钥分发以达到一次一密,并满足业务对效率的需求,从密钥分发的角度探讨了实现目标的方法。它分析了固网支付业务系统结构和安全需求,以及固网支付中现行的密钥分发机制,针对现行机制可能存在的问题并综合各种密钥分发机制提出一种适用于多内容提供商的新方案。
To ensure security of e - payment on PSTN network and achieve a balance between security and efficiency, the structure of the e - payment system was analyzed in this paper and the security demand of the system was explained at the same time. Besides, the current key distribution mechanism in e - payment service network was described in detail. Finally, acoarding to the irregularity of the current mechanism entity and different kinds of key distribution mechanism, a new scheme to secure e- payment on PSTN was presented.
