What can be improved so that the the susceptibility to frequency analysis attack problems of alphabetic subsitution methods like Caesar Cipher and Monalphabetic Substituion can be removed? We can use a different set of encryption mapping in the order of each alphabet encryption. Suppose we have the sentence again ATTACK STARTS ON SEVEN TONIGHT We […]
One information that is truly important when conducting Cryptographic Attack, it is: the nature of the plaintext. Is it a sentence of a particular language? or is it of some software code? If we know the fundamental nature of the plaintext, then our code breaking job could be a bit easier. If it is of […]
In cryptographic study, we know the simpliest way to conceal the information is by ‘substitution’. You replace the original word/alphabet by another word/alphabetic ‘systematically’. The word ‘systemtically’ have to be in place because you need a way to decrypt the concealed message. In Latin language system, we use a alphabet to replace another one sequentially […]
