Transactions done online everyday are generating terabytes of information data. Securing this information over the internet is a challenging task. Cryptography plays a major role in securing this data and providing confidentiality to authenticated and genuine users. Various parameters such as encryption time, decryption time, memory consumption, weakness and strengths are to be evaluated before choosing the right algorithm. IoT devices are constrained in their resources. Light weight cryptographic algorithms are meant for such resource constrained devices. This paper gives a comparative study of few light weight cryptographic algorithms. This paper also discusses the encryption and decryption of data collected from IoT sensor and their performance evaluation.
