摘要
本文介绍一种新的通过公用电话网(PSTN)为授权用户提供时间信息查询、认证服务的电话授时系统———话路时间校对和认证系统.本文主要分两级讨论了该系统的安全策略,其中包括用户身份鉴别和密钥分配、信息加解密、数据库加密及访问控制.实验结果表明该实施方案完全满足系统安全需求.
A new time-giving system named PSTN-based time-collating and authentication system is proposed. The system provides services of time information query and authentication. In this paper the security strategies of the system are mainly discussed in two levels, including the user identity confirmation and key distribution, the data encryption , the database encryption and the control of visiting to the encrypted database.
