Thus, lightweight cryptography methods are proposed to overcome many of the problems of conventional cryptography. While our conventional cryptography methods, such for AES (encryption) and RSA (signing), work well on systems which have reasonable processing power and memory capabilities, these do not scale well into a world with embedded systems and sensor networks. In current computer systems, cryptography provides a strong, economical basis for keeping data classified and for verifying data indignity. Cryptography includes a set of techniques for scrambling or disguising data so that it is available only to someone who can restore the data to its original form. The goal is to allow the intended recipients of a message to receive the message properly while interrupt eaves- droppers from understanding the message. The field of cryptography deals with the procedure for conveying information securely. Best solution is use of some cryptography algorithm which encrypts data in some cipher and transfers it over the internet and again decrypted to original data. Thus Security of data is the biggest concern of internet users. In Today’s world Sensitive data is increasingly used in communication over the internet.
