Define Classical Cryptography
We know that it was the spartans the most warlike of the greeks who pioneered cryptography in europe. Around 400 bc they employed a device known as the scytale.
Classical cryptography is based on the mathematics and it relies on the computational difficulty of factorizing large number.
Define classical cryptography. However they are also usually very simple to break with modern technology. In cryptography a classical cipher is a type of cipher that was used historically but for the most part has fallen into disuse. Classical cryptography permutations and substitutions.
First define a measure of roughness. In contrast to modern cryptographic algorithms most classical ciphers can be practically computed and solved by hand. The device used for communication between military commanders consisted of a tapered baton around which was wrapped a spiral.
The security of classical cryptography is based on the high complexity of the mathematical problem for the instance factorization of large number. Cryptography the art or science encompassing the principles and methods of transforming an intelligible message into one that is unintelligible and then retransforming that message back to its original form.
