Security is very essential for all over the world. In every minute researchers are engaged in finding out the best possible way to make the security stronger. Many techniques are used to implement the security by the researchers. The ECC (Elliptic Curve Cryptosystem) is one of the simplest method to enhance the security in the field of cryptography. The aim of this paper is to generate light weight encryption technique based on the ECC method. Here, the session key is generated to secure the original message. SHA2-512 and SHA2-224 bits hash algorithms are applied for session key generation. First of all, plaintext character is taken by the user, the character is converted into ASCII value and then implement ECC technique on it.
