1.Abstract:
The need for security in WSNs is unavoidable. Applications such as military, medical care, structural monitoring, and surveillance systems require information security in the network. As current security mechanisms for WSNs are not sufficient, development of new security schemes for WSNs is necessary. Nowadays research and applications of Wireless Sensor Network have attracted people’s attention. Since sensor nodes in WSN are resource-constrained, the security solutions for WSN become difficult. Cryptographic hash functions are a valuable tool in cryptography. They are applied in many areas of information security to provide protection of the authenticity of messages, data integrity verification which prevents modification of data from going undetected. Traditional security measures require heavy communication and computational resources and cryptographically complex security solutions for sensor networks are not suitable for WSN. In this paper, I have proposed an algorithm for node authentication by using cryptographic hash function and public key cryptography technique in Wireless Sensor Network .Which can fulfill confidential communication and mutual authentication between nodes, enhances scalability, node authentication security and prevents node impersonation.
2.Introduction:
Wireless sensor networks consist of a large number of such sensor nodes and are able to collect and disseminate data in areas where ordinary networks are unsuitable for environment. Wireless sensor networks use new technology and standards. They involve small, energy-efficient devices, hardware/software co-design, and
