【摘要】：随着通信技术、计算机处理技术、传感技术、控制技术等现代信息技术的发展,出现了众多满足现代化管理需求的智能交通系统。然而目前许多计算机网络正在遭受严重的安全威胁,尤其交通局内部网络的安全成为管理隐患。用户认证作为保障内网安全的第一道关卡,起着至关重要的作用。传统的用户认证普遍基于用户账号和口令的方式认证,这已经不满足智能交通系统的安全用户认证需求,新的需求是要求系统可以同时验证用户的口令和位置信息。本文针对不同的应用场景和攻击类型提出四个基于位置的用户认证协议。首先设计了可验证用户位置范围的基于网络标识的ULNI协议,随后利用距离约束技术设计ULDB协议考虑了位置验证的安全性,然后利用多点定位技术提出ULVM协议使得验证用户的精确位置成为可能,最后找到一种可以抵御共谋攻击的BRM模型,并利用此模型设计了ULBRM协议。这些协议的研究与提出,为智能交通系统的用户认证提供了具体的理论支持,解决目前没有同时验证用户口令和位置信息的问题。同时,本文通过智能交通系统登录模块的需求分析,选择合适的基于位置的认证协议ULNI协议应用于系统的登录模块。测试表明,协议可以满足登录模块同时验证用户口令和位置的需求,并且用户登录时间不超过1s。具有较好的安全性和应用价值。
[Abstract]:With the development of modern information technology, such as communication technology, computer processing technology, sensing technology, control technology and so on. There are many intelligent transportation systems to meet the needs of modern management. However, many computer networks are facing serious security threats. In particular, the safety of the internal network of the Bureau of Communications has become a management hidden danger. User authentication is the first level to ensure the security of the internal network. Traditional user authentication is generally based on user account and password authentication, which can not meet the needs of intelligent transportation system (its) security user authentication. The new requirement is that the system can verify the user's password and location information simultaneously. In this paper, four location-based user authentication protocols are proposed for different application scenarios and attack types. Firstly, the verifiable user location is designed. Scoped ULNI protocol based on network identification. Then, the security of location verification is considered in the design of ULDB protocol using distance constraint technology, and then the ULVM protocol is proposed to make it possible to verify the exact location of the user. Finally, we find a BRM model which can resist the collusion attack, and use this model to design the ULBRM protocol. It provides specific theoretical support for the user authentication of intelligent transportation system and solves the problem that the user password and location information are not verified at the same time. At the same time, this paper analyzes the requirement of the login module of intelligent transportation system. The suitable location-based authentication protocol (ULNI) is applied to the login module of the system. The test shows that the protocol can satisfy the needs of the login module to verify the user's password and location simultaneously. And the user login time is not more than 1 s. It has good security and application value.
