Sir Arthur Conan Doyle. r and r = occurs in multiple test cases, there may be some wasted effort but testing soundness is not af-fected. Software testing typically has a vast number of pa- rameters and corresponding value (1)Substitution cipher. :. In substitution cipher each element in the plain text is mapped into (replaced by) another element to generate the cipher text.. (2)Transposition cipher:. In transposition cipher the elements of the plain text are rearranged to generate the cipher text.. Session 4. Contents. Linear cryptanalysis. Differential cryptanalysis. 2. /48.

Cryptology is the umbrella word that represents the art of enciphering words so as to protect their original meaning (cryptography) and also represents the science of breaking these enciphered codes (cryptanalysis).
