Security mechanisms on key pre distribution in wireless sensor network

Abstract

key distribution and energy efficiency plays an important role in wireless sensor newlinenetworks a wireless sensor network has a large number of tiny sensors with limited newlinecomputational capability memory space and power resource to achieve security in wireless newlinesensor networks it is important to have the ability to encrypt messages sent among sensor newlinenodes keys for encryption purposes must be agreed upon by communicating nodes due to newlineresource constraints achieving such key agreement in wireless sensor networks is non trivial newlinemany key agreement schemes used in general networks such as diffie hellman and publickey newlinebased schemes are not suitable for wireless sensor networks newline newline
