摘　　要：近几年来,智能家居产业和研发正在呈指数级增长,但传统的安全策略往往不适用于智能家居设备。由于目前智能家居设备普遍具有分散拓扑网络和自身资源受限的特点,智能家居设备在身份认证和密钥管理等方面存在巨大安全风险。针对以上问题,提出一种新型的智能家居设备门限群签名方案。该方案将SM2密码算法和门限群签名技术相结合,可实现设备的安全可靠认证,并大大提高密钥在使用过程中的安全性。同时证明了系统的正确性和安全性,包括匿名性、可追踪性和保密性。最后对系统进行仿真测试,结果表明该在满足安全特性的前提下该系统表现出良好的性能。In recent years,the smart home industry and research are growing at an exponential level,but the traditional security strategy is not suitable for smart home devices.Because the current smart home devices generally have the characteristics of decentralized topology network and limited resources,these devices have huge security risks in the aspects of identity authentication and key management.This paper proposes a new threshold group signature scheme for smart home devices.This scheme combined SM2 cryptography algorithm and threshold group signature technology to realize the security and reliable authentication of the device,which greatly improved the security of the key in the process of using.We also demonstrated the correctness and security of the system,including anonymity,traceability,and confidentiality.Finally,the simulation results show that the system has good performance under the premise of satisfying security.
