摘要
提出一种在嵌入式Linux操作系统上运行TCP/IP协议的解决方案。介绍了Linux内核,在此基础上结合嵌入式系统特点,对TCP/IP协议栈进行简化,提出总协议栈的体设计。根据军用通讯要求着重讨论了网络协议的安全问题,参考现在通用的网络安全模式PGP,对TCP/IP协议栈进行修改,主要是在应用层中加入了加密、认证以及密钥分配过程。加密过程采用DES和RSA组合算法,保证其安全性、可行性以及时效性。
The paper discussed a kind of solution is to run TCP/IP protocol on the embedded Linux operating system.First,a brief introduction of the Linux kernel,and then with embedded systems based on the characteristics of the TCP/IP protocol stack can be simplified and put forward the overall design.Among them,according to military communications requirements focused on the security of network protocols.Finally reference is now common network security model of PGP,on the TCP/IP protocol stack modifications,mainly in the application layer by adding encryption,authentication and key distribution process.DES and RSA encryption process uses a comprehensive algorithm to ensure their safety,feasibility and timeliness.
