安全问题是移动IP技术的核心和瓶颈。针对目前公安移动警务系统安全需要,从系统总体目标和安全策略等方面展开研究,提出了一种基于专网的移动警务系统安全接入设计方案。重点对移动公网接入、移动终端认证系统、数据传输安全、安全管理以及与公安内网数据交换的安全策略进行研究和设计。 Security is the core and bottleneck of mobile IP technology. Aiming at the current security needs of police mobile police system, this paper studies the overall system objectives and security policies, and proposes a secure access design scheme for mobile police systems based on private network. Focus on the mobile public network access, mobile terminal authentication system, data transmission security, security management and public security network data exchange security strategy research and design.
