Version Control for Authentication in Distributed Reprogramming in Wireless Sensor Networks

Abstract

Reprogramming is a technique used in wireless sensor networks (WSN) to update the software part of sensor nodes from remote locations over wireless links during run time of the network. However, reprogramming needs to be integrated with secure and efficient authentication technique to avoid any unauthorized access to sensor nodes. This paper gives an efficient authentication technique for distributed reprogramming using version numbers from version control operation of reprogramming. The Existing version control technique is modified to achieve both authentication and version control in reprogramming. The proposed method is compared with the two other algorithms defined for authentication of users in (Das, Two-factor user authentication in wireless sensor networks. IEEE Trans Wireless Commun 8:1086–1090, 2009) [3] and (He et al, SDRP: a secure and distributed reprogramming protocol for wireless sensor networks. IEEE Trans Ind Electron 59:4155–4163, 2012) [5]. The comparative analysis shows version control method is more efficient and is robust to impersonation attack.
