A robust energy efficient and secure data dissemination protocol for wireless body area networks

Abstract

Today wireless body area networks (WBAN) offers a competent resolution to real-time monitoring and exposure of patient's fitness information. The configuration parameters adjustment requires the data dissemination through WBAN. For data dissemination different protocols are proposed. A multiple one-way key hash chains were proposed for secure data dissemination. In this protocol, SHA-1 based hash functions and AES based encryption was utilized to provide security. However, the complexity of SHA-1 is overhead for WBAN. In this paper the complexity is reduced by introducing simple hash chain based protocol which is utilizing Chaos baker map for security. This Chaos baker map method randomizing data before hashing. Hence, this protocol presents instant authentication and competent to tolerate node compromise. This paper also provides the experimental consequences of Chaos baker map based simple hash function protocol in a network of source restricted sensor nodes, which proves its effectiveness.
