Elliptic Curve Cryptography in Constrained Environments: A Review

In order to provide security in constrained environments, Public Key cryptography is being used extensively. Elliptic Curve Cryptography (ECC) is one of the best Public Key encryption techniques. ECC uses smaller key sizes compared to traditionally used RSA based cryptosystems for nearly the same security status. ECC offers great potential for the future research due to the ever growing demand for compaction of the devices and load balancing for environments where there are memory, bandwidth and computational constrains.
