Cryptography Using Modern Ciphers (Xor and Transposition)
Satish Kumar Garg · Research Journal of Engineering and Technology · 2022
In the present paper the author has suggested a symmetric key cryptographic system where two modern ciphers, namely XOR and Transposition 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.
