A Survey Paper on Hop by Hop Message Authentication in Wireless Sensor Network

Abstract- confidentiality and security to the data is actually provided by an authentication. Authentication involves the confident identification of one party by another party or a process of confirming an identity.But now a days there are various methods for authentication such as Message Authentication Code, Signcryption, Key Aggregate System are emerged very rapidly for better security precaution. This paper try to investigate how to provide authentication in wireless sensor networks. Other goals are to give an introduction to general security in wireless sensor networks. As Wireless sensor networks are the point of attention of numerous researchers regarding the security issue in the past several years. Message authentication is one of the most effective way to find out an intruder who can compromise with the nodes and can access to the data and corrupt the data in wireless sensor network. There were various methods have been developed to solve the problem such as symmetric key cryptography and public key cryptography. Each would have their own problems such as threshold overhead and key management and computation overhead and scalability.In order to solve such problem we developed a new authentication scheme using the elliptic curve cryptography.In this scheme any node can transmit n number of message without threshold problem. This paper is to do survey before actually implementing it
