Non-repudiation Scheme of Smart Home Based on Cloud Service

Smart home control model based on cloud service not only solves the problem that different equipment manufactures carry out diversified long-range control model, but also provides key technology for gang control of multiple devices. However, the operation controversy among user, cloud provider and equipment can't be ignored. To solve the operation repudiation of participators, an ID-based non-repudiation scheme is presented. The security analysis shows that the presented scheme which involves signature, signature verification, feedback signature, feedback signature verification and execution instruction solves the possibly controversial problem in process of smart home control, and improves the security of based on cloud service smart home system.
