DATA DISSEMINATION PROCESS IN WIRELESS BODY AREA NETWORKS FOR HEALTHCARE APPLICATIONS

Abstract Advancements made in the field of wireless communication have paved the innovation of Wireless Body Area Networks (WBANs). It's a sort of wearable computing devices embedded into tissue of human parts to monitor the health issues of patients from anywhere. Though, it offers variety of fruitful services, security is the major concern. Data collection and data dissemination process are to be effectively handled to offer better end-to-end services. In this paper, we design an access control scheme which stores, transmits and retrieve the sensitive data to the concern users via certificateless signcryption scheme. Controller is the main part of WBAN architecture where the data are preserved. When the user is in need of patient's data, the retrieval process from controller to user should be safer and easier process. The ciphertext are duly signed in order to make strong authentication process. When the user satisfies with the established secret key, the ciphertext data is returned. Experimental analysis is done for security purpose in terms of efficient key generation, processing cost and energy consumption. Our proposed scheme achieves lessened storage space with efficient key updates and data retrieval process within stipulation period of time.
