Enhancing the Efficiency of Secure and Distributed Reprogramming Protocol for Wireless Sensor Network

Abstract

Wireless reprogramming is a method of modifying the working of existing code or transferring new code image to sensor nodes in order to improve its performance in sensor network. Reprogramming the sensor network in a secure way is a challenging task. For security purpose every code update must be authenticated to prevent an attacker from installing malicious code in the network. A Secure and Distributed Reprogramming protocol named SDRP is the first protocol which has been established to reprogram the sensor nodes in a distributed way without involving the base station, where different reprogramming privileges will be given to several authorized users. The protocol uses identity based cryptography to secure the reprogramming and also to reduce the communication overhead and storage requirements of each node. After analyzing this protocol, it is found that it is tractable to impersonation attack. Hence adding 1-byte redundant data has been proposed as a solution to prevent the impersonation attack. The proposed solution will improve the performance and efficiency of the SDRP protocol.
