鉴于市政管理数据中包含大量敏感信息，为解决目前移动终端访问市政平台所存在的安全问题，采用MD5和DES算法，设计一移动通信中间件，对现有的网络进行改进以实现平台的安全机制。MD5算法用来实现身份认证过程，DES算法结合非对称加密和数字签名技术来保证信息的安全传输。该中间件可以以动态库的形式集成在客户端设备与市政管委的Web服务器上，因此可以不需要对现有资源进行较大的改动，以较小的代价达到安全性目标，大大降低部署的难度。
Abstract: As the database of municipal administration contains large amounts of sensitive information， we designed this mobile middleware to optimized the exsiting platform and protected the sensitive data be attacted. This middleware is based on MD5 and DES algorithm. MD5 algorithm is used to implement the authentication process.DES algorithm combined with asymmetric encryption and digital signature to ensure the safety of information transmission. The middleware can be integrated in the client device and the Web server of the municipal in the form of dynamic libraries.You can achieve the security goals without need to carry out major changes to the existing resources， greatly reduced the difficulty of deployment.
