Abstract
In IEEE 802. 15. 4 Body Area Networks (BAN), security solution is required for data confidentiality, authentication and integrity at low cost. But the existing solutions for WBAN either provide any one of the security features or provide all the features with high cost. In this paper, we propose to develop light-weight security architecture for IEEE 802. 15. 4 BAN. It consists of local sensors situated on various parts of the body which forms various clusters. The local sensor collects data from different parts of the body and transmits the data to their respective cluster head. A wireless local gateway (WLG) is deployed within the patient's home and a hospital gateway (HG) is set in the hospital. The cluster head transmits the data securely to the WLG. At WLG, a new message is created by aggregating all messages from various clusters of a patient. A secret key is generated using Elliptic Curve Cryptography (ECC) for encryption and the encrypted message with message authentication code (MAC) is transmitted to the HG. At the destination, the doctor first authenticates the MAC and then decrypts the data with the secret key and monitors the patient's health condition. Thus the data cannot be read by any other person, providing a secured transmission at low cost.
