基于PKI的跳端口通信安全性增强技术

摘要

Aiming at the security issues of the communication port expressed and transmitted in the end-hopping technology, a port-hopping communication technology combined with PKI theory was proposed. The model was established,then the key problems of the model were discussed. The result shows the communication based on the PKI-authentication technology and extemporaneous port-consulting can prevent hackers from seizing the hopping rules of port, and it is an effective way to secure the information. The work analyzes the security of the model and verified the feasibility comparing with the original port-hopping communication technology.%针对跳端口技术中端口表传输过程中的安全问题,提出了基于PKI的跳端口通信技术.构建基于PKI的跳端口通信模型,详述了系统模型及实现过程,并对该技术中同步机制、跳变频率、密钥管理等关键问题进行了探讨.结果表明,通信双方通过采用基于PKI的认证以及临时协商端口号,可减少跳端口表在传输过程中的安全隐息,增大攻击者假冒、截获等攻击难度.相对原有跣变系统,基于PKI的跳端口信息隐蔽性及跳端口通信安全性有效增强.
