The research recorded and analyzed determines which method is more efficient for decoding encryptions. The importance of these decryption methods is to see whether Frequency Analysis is essential in ...

A substitution cipher is a cipher that maps each symbol in the plaintext to a symbol according to a permutation of the alphabet. A breakpoint is a location in the ciphertext where the cipher changes.

To break the Enigma code during the Second World War, British computer scientist Alan Turing developed a mathematical model to unlock the cipher faster than any human. Today, a group of University of ...

Al-Kindi’s method of decoding Building on the work of scholars such as Al-Khalil, Al-Kindi introduced frequency analysis to crack the substitution cipher. Scholars of the Quran had been trying to ...

Some ciphers have simple keys, others, complex ones. The key for a cipher used by Augustus Caesar, some 2,000 years ago, was simple enough: The receiver just had to shift the alphabet one position.

The Double Transposition Cipher Back to Crack the Ciphers This was one of the most secure hand ciphers used in the Second World War. It was used by both the Allies and the Axis, and served both well.

This brief message, which former NASA administrator George Low named ‘The Martian Cipher’, was intercepted in 1969. It took the space agency almost 50 years to decode it. This deciphering is ...
