The identity-based signature scheme uses NAI ( network access identifier ) as public key and simplifies the key management in wireless mobile environment, so it can resolve the deficiency in PKI-based authentication mechanism. 该方法使用NAI(networkaccessidentifier)作为公钥,简化了无线移动环境中的密钥管理问题,有效地解决了基于PKI(privatekeyinfrastructure)的认证机制的不足。
Thirdly, to address the limitation of the network access control based on IP address, we proposed a network access control mechanism based on permanent identifier ( LISA-NAC ). LISA-NAC provides an accurate and efficient fine grain access control mechanism for the edge network. 首先,针对TCP/IP体系结构下基于IP地址的访问控制存在的缺陷,我们提出了基于LISA固定标识的网络访问控制机制LISA-NAC,从而为边缘网络提供了准确、高效的精细粒度访问控制机制。
