Secure distributed framework based on seamless key session for smart home environment

Smart home environment comprises high-capacity and low-capacity sensors. These sensor nodes interact with daily activities of users and they communicate with each other to perform particular tasks. A set of instructions in insecure network during communication can result in a deadlock due to attack of adversary. Such deadlocks can be a severe risk for the security of user’s activities in smart home environment. Recent critical security attacks in smart home environment exposed that how communication channels turned low-capacity sensors into harmful attack for illegal activities which later lead to damage security and privacy. Therefore, a suitable framework is needed to overcome security pitfalls and to protect user’s activities by establishing secure key session between sensor nodes. This study has proposed new secure distributed framework which is based on secure cryptic setup and efficient key-session authentication process to strengthen resource-limited devices. Secure distributed framework shares attributes of seamless key session among low-capacity nodes after sensing daily activities of user based on activity model to establish cryptic link by keeping identity of devices faceless. Distributed activity key-session model of secure distributed framework stores the user’s activities via sensor nodes and these nodes forward the data to nearby gateway in smart home environment. This scheme regularly updates token authentication process and enables stringency of nodes against severe attacks during communication. Secure distributed framework originates from distributed trajectories’ connection among sensors in network by avoiding deadlock and suspicious activities. Moreover, secure distributed framework works more efficiently on resources-restraint nodes as compared to previous schemes from literature while security is significantly enhanced. This article has focused on new encrypted key-session attributes of encrypted daily living activities to fortify low computational devices and enables wireless nodes for secure trajectory association. Preliminary simulation is performed in well-popular security tool automated validation of Internet security protocol applications to check the feasibility of proposed secure distributed framework and the required results are achieved.
