WIA-PA网络安全机制的设计与实现

Design and Implementation of the Security Mechanism in WIA-PA Network

WIA-PA是我国具有自主知识产权的工业无线标准,是工业无线领域三大主流国际标准之一。该文针对WIA-PA网络的特点,以WIA-PA安全标准为依据,提出了网络密钥管理机制保证密钥的安全性、安全入网机制鉴别加入节点身份的合法性和安全数据流传输机制能保障数据的机密性和完整性。经搭建测试平台验证:安全机制提高了网络的安全性,增强了WIA-PA网络抵抗威胁和攻击的能力,而且分析表明在节点资源开销方面合理,具有较好的性能。

WIA-PA was the industrial wireless standards that was research and developed in our country,which was one of the three major international standards. In this paper,with the characteristics of WIA-PA,in accordance with WIA-PA standards,we propose the key management mechanisms to ensure the keys of network security,the security joining mechanism to check the legality of joining nodes,the security mechanism to protect the data to transmit confidentiality and integrity. With the verification of test platform,these security mechanisms improve security of network,resistance to WIA-PA network threats and attacks to some extent. Moreover. analysis shows that the cost of the security mechanism was reasonable,with good performance.
