Survey on elliptical curve cryptography

The main objective of our survey is based on elliptical curve cryptography. It provides security for encryption and decryption of data. We have gone through several papers, each paper describes about some protocols. some of the papers are related to Text based, Wireless Communication and java as implementation tool .The above methods has its own protocols. One is based on customizable cryptography. It produces hardware designs for ECC. Encryption is a process of encoding messages or information in such a way that only authorized parties can read it. Decryption is a process of decoding data that has been encrypted into a secret format. It requires a secret key or password.
