A Review on Different Resource Efficient Key Management Schemes for Wireless Sensor Networks

Chidambaram G, Edwin Prem Kumar G

The wireless sensor networks needs security for transferring the sensed data to the base station. There are many possible ways to attack the transferred data, for reducing the attackssecurity is mostly needed for the network. Key management is the method of using cryptographic keys to provide security. The resources of wireless sensor networks must also be considered for the establishment of keys. This paper explains about the differentmechanisms or protocols that are possible for wireless sensor networks to establish the authentication keys in resource-efficient manner. This paper also presents the different cryptographic methods that are used by the sensor networks for securing its data. This paper does not conclude any specific protocol which is suited for establishing cryptographic keys in resource-efficient manner. But the usage of protocols depends upon the applications of the wireless sensor networks.
