Empirical Evaluation of ECC Batch Verification Algorithms of Digital Signature in Wireless Sensor Network

Abstract

Wireless sensor network (WSN) is an emerging topic in wireless communication where various sensor nodes are connected over the internet for data exchange. Exchanging the information over the WSN is very critical; therefore, it requires authentication and security mechanisms to ensure integrity and confidentiality. To avoid unauthorized use of WSN, the authentication through a digital signature turns into an essential task in WSN. Verification of individual signature is taking too much time and it is not suitable for wireless sensor network. Digital signature verification time can be reduced by using batch verification techniques in WSN. Therefore, the goal of this research is to examine and analyze the different type of batch verification algorithm based on Elliptic Curve Cryptography (ECC). With respect to security, the entire algorithm is identical to the standard Elliptic Curve Digital Signature Algorithm (ECDSA) verification algorithm. These algorithms are effectively limited to small batch sizes.
