基于发布/订阅的需求响应安全通信机制设计

Publish / subscribe based security communication mechanism for demand response

随着网络攻击的日益增多,需求响应通信安全是一个值得研究的课题。文中基于发布/订阅模式实现了通信的灵活性和动态性,基于OpenID的动态密码技术进行身份认证,通过认证后进行基于角色的访问控制,信息经加密后进行通信。最后通过案例验证和安全分析表明,在计算开销增加有限的情况下,该机制能有效增强需求响应通信的安全性。

The security of demand response communication is deserving research against the evolving cyber attack. This work based on publish / subscribe pattern achieves flexibility and dynamic topology.Authentication utilizes dynamic password based on Open ID technology. The encrypted information is transferred through public wireless network. As shown in the case study and security analysis,publish /subscribe based mechanism for demand response enhances the communication security at the price of limited increasing computation overhead.
