Robust ECC-based Three-factors Authentication and Key Agreement for Smart Home

Abstract

With the deep exploration into artificial intelligence (AI) technology, smart home has become a major development trend. Authentication and key agreement (AKA) protocols are widely used in smart home for communication between users and devices as an important means to protect communication security. However, traditional AKA protocols cannot meet the needs of smart home environments in terms of both security and overhead. To reduce the cost of deploying AI-based devices, a practical ECC-based AKA protocol is proposed, which can achieve secure authentication among users, gateway nodes and AI-based devices and generate session key. Moreover, biometrics are implanted through specific devices and adopted as an authentication factor to resist password leakage attack. The security is proven by using Real-Or-Random (ROR) along with informal security analysis. Furthermore, the widely accepted AVISPA is used to verify whether the protocol can resist active attacks. Finally, experimental simulations are completed between the proposed protocol and the related works the results show that ours keeps a balance in security and performance.
