摘要
为解决VPN(Virtual Private Network)在移动多媒体城域网应用中的安全性问题,提出一种VPN链路建立和认证的方法。该方法通过使用临时IP地址,实现了匿名通信,从而有效隐藏了用户的私人信息,避免将信息泄露给其他的专用局域网,进一步加强了VPN组网模式的安全性。同时,通过采用单钥加密体制的加密方法,对数据信息进行加密封装处理,确保了用户数据信息在传输过程中的保密性和完整性。
To address the VPN(Virtual Private Network) applications in mobile multimedia metropolitan area network security issues,a VPN link establishment and certification method is proposed.The temporary IP address si used in the method to achieve anonymous communication,which effectively hides the users private information to avoid information leaks to other dedicated local area network,the VPN network model to further enhance security.Meanwhile,in a single-key encryption system,encryption,encryption of data processing package,to ensure that the user data during transmission confidentiality and integrity.
