Trustable Body Area Network for Emergency Response

Abstract

In the medical field, Wireless Body Area Networks (WBAN) play the main role in keeping users healthy by offering convenient services for doctors and patients. However, the attacker is prevented from tampering with the sensor data by communicating through an unsecured channel, which prevents the forwarded packets from their hazardous origins. Several methods of safe authentication are suggested for bolstering the trustworthiness of the channels of communication in protecting user data. A Trustable Body Area Network (TBAN) for Emergency Response approach to protect the medical sensor nodes from untrusted nodes and increase efficiency. Simple trust and compound trust computations are used to isolate untrustable nodes. In addition, this system applies a hash-based signature with a onetime password to confirm the second-level sensor node authentication in the WBAN. The simulation result demonstrates that the proposed system detects the untrustable sensor node efficiently and reduces the network delay.
