Data Security using Multi-Level Encryption
Satish Kumar Garg · Research Journal of Engineering and Technology · 2022
In the present paper the authors have suggested a unique symmetric key cryptographic technique where three modern cipher, namely transposition cipher, rotation cipher and XOR ciphers have been used. The cipher text thus obtained is hard to crack because a teraflop super computer may need upto 3400 Years to find all possible permutations even for a plain text consisting of 10 characters.
