摘　　要：工业控制网络中通信数据的保密性是信息安全的一个方面.通信数据保密性包括数据本身的安全性和会话密钥的安全性,该问题的难点在于保密性要满足工业控制网络的较少资源消耗和较少时间消耗要求.针对工业控制网络中周期性数据的属性,本文提出了一种基于NTRU(Number Theory Research Unit)的端到端轻量级混合密码机制,NTRU-RC4机制.在NTRURC4机制中,周期性数据采用对称密码RC4算法进行保护,考虑到安全性能因素会话密钥采用轻量级的非对称密码系统NTRU算法进行保护.轻量级混合密码机制既实现了周期性数据安全性又实现了会话密钥安全性,原型系统的测试验证结果表明,较少的时间消耗保证工业控制网络的性能.Communication data confidentiality is a part of security in industrial control network.Communication data confidentiality includes data security and session key security.It is difficult point that confidentiality technology demands less resource consumption and less time consumption in industrial control network.According to the attributes of periodic data in industrial control,an end-to-end lightweight hybrid cipher mechanism based on NTRU(Number Theory Research Unit),NTRU-RC4 mechanism,is proposed.In NTRU-RC4 mechanism,symmetric cipher RC4 is used to protect periodic data and lightweight asymmetric cipher NTRU is used to protect session key because of security performance.The end-to-end lightweight hybrid cipher mechanism implements both periodic data security and session key security.Test results of prototype system show that the less time consumption ensures performance in industrial control network.
