基于数字身份认证系统的即时通讯系统应用探讨

介绍海河水利委员会即时通讯、数字身份认证等系统的技术架构，对即时通讯系统升级的2种方案：即时通讯系统与统一用户管理系统结合通过用户名/密码方式进行登录，和即时通讯系统与认证系统深度集成通过USB Key 登录的方案，从原理、实现方法、实施步骤、开发工作量、系统安全性、用户接受程度等方面进行详细分析，最终选择即时通讯系统与第三方统一用户管理系统结合，通过用户名/密码方式进行登录的方案对海河水利委员会即时通讯系统进行升级改造，升级后的系统完善了离线文件处理稳定性、组织机构排序灵活性等功能，极大地保障用户个人信息及工作文件的安全与不外泄。

Application of Instant Messaging System Based on Digital Identity Authentication System

This article introduces the technical framework of instant messaging system and digital identity authentication system of Haihe River Water Conservancy Commission （HWCC）. From the perspectives of theory, methods, steps, workload, system security and user acceptance, it gives a detail analysis on two solutions：one is a combination of the instant messaging system with the universal user management system by log in username/password, and another is to log in with a UKEY on the basis of a deep integration of the instant messaging system and the CA system. In the end, the solution of logging in by inputting username/password on the basis of a combination of the instant messaging system and a third-party universal user management system is chosen to upgrade the instant messaging system of HWCC. The upgraded system improved the function of the offline file handling stability and organization flexibility. It greatly guarantees the safety and no leak of users’ personal information and working file.
