DEVELOPMENT OF ENCRYPTION AND DECRYPTION TECHNIQUE TO SECURE THE CONFIDENTIAL DATA

Abstract

Cryptography is the science of converting one form of data into another form, to provide security. Converting plain text to cipher text is encryption and converting cipher text to plain text is decryption. In the today’s leading world huge amount of data are stored and transferred every second. But the issue is to provide the security to that data. For this Encryption and Decryption is considered as one of the better techniques. Two types of approach are used for encryption and decryption that is Symmetric key cryptography and Asymmetric key cryptography. RSA is one of the algorithms used in Asymmetric key cryptography. RSA algorithm is better in terms of security, but this algorithm reduces the speed of mutual authentication. In this paper, we have developed a modified RSA approach where the speed of Mutual authentication is enhanced with the help of modified RSA algorithm and a strong key is used to provide better security.
