Secure new node ID assignment for internet integrated wireless body area networks

Internet integrated sensor networks have gained much importance and exponential growth in wireless body area networks (WBAN) over the last few years. These networks are used in health services to remotely monitor the health of patients and send/receive sensitive, time critical medical data. Because of the wireless and broadcast nature of WBAN, it is easy for an adversary to get, inject, or update the information transmitted in the medium or launch many security attacks. To protect the sensitive data of the patient, we propose a secure communication strategy for different sensors to form a WBAN. Here, a new node ID is assigned for sensors by using public key cryptography to communicate in the network. An energy utilization and communication cost analysis show that our approach incurs less communication overhead as compared with the recently proposed secure solutions in WBAN. The complexity analysis show that the proposed model works efficiently for secure communication in WBAN.
