Hybrid cryptosystem in wireless body area networks using message authentication code and modified and enhanced lattice-based cryptography (MAC-MELBC) in healthcare applications

摘要

Wireless Body Area Networks (WBAN) is a network of sensor devices that are connected together located in the clothes, on the body or underneath a human's skin to monitor patient's health continuously and communicate with required resources. Recently, WBAN offers many applications like remote health monitoring, sports, military, healthcare, and so forth. In healthcare, it improves the patient's life quality based on a faster, accurate diagnosis of diseases and better treatment of patients. Security is a major challenging task to protect the life critical data against various security threats. Many health security systems have been proposed by various researchers for WBAN. Even though, none of the security algorithms achieved high security with efficient time. Hybrid encryption technique plays an essential role to provide high security as compared to previous methods. Therefore, this paper introduces Hybrid Encryption Algorithms (HEA) by combining symmetric key (Message Authentication Code [MAC]) and asymmetric key cryptographic techniques (Modified and Enhanced Lattice-Based Cryptography [MELBC]) are used to provide strong security, because symmetric techniques provide a high level of security and asymmetric provides key administration. Based on experimental results, it is proven that the proposed algorithm HEA provides high security than other security algorithms.
