Encryption of Data based on Triple encryption and Affine Algorithm

Abstract

In recent years in view of the recent scientific and technological development, Encryption has emerged as a solution and is critical in the information security system. To protect the shared data, a variety of techniques are needed. To begin, data must be encrypted before being sent from sender to receiver using a cryptographic algorithm for encryption. Second, the receiver can display the original data using decryption techniques.

Encryption is a well-known method of safeguarding classified information. It is a procedure for converting text or data into an unreadable format for the purpose of hiding this data or is converting plaintext to ciphertext is an operation. In conjunction with an algorithm or a key. The current research focuses on using cryptography to protect data as it is being transmitted, we implemented three encrypt techniques (Caesar-Reversing-zigzag) by combining the three codes called triple encryption for encrypting the message, re-encoding the encrypted text using the affine cipher. The present work is implemented by using Visual Basic 6.
