A Comparative Analysis of Cryptographic Keys and Security

In wireless sensor networks (WSNs), security has a fundamental significance. With advancement in use of internet of Things (IOTs) applications there are challenges to empower the sensor nodes with secure and lightweight algorithms that can run efficiently with minimum energy consumption as well as to provide the security comparable to traditional computer networks. In this paper, the analysis is concentrated on the key generation techniques, encryption/decryption solutions. We have briefly discussed about security algorithms with their limitations in sensor network. We also presented the importance to emerging technology for providing security in wireless sensor networks.
