In modern cryptography, concepts like confidentiality, data integrity, authentication, etc. play a crucial role. The Hill Cipher … See more Hill Cipher, in the pretext of classical cryptography, follows a polygraphic substitution cipher, which means there is uniform substitution across multiple levels of blocks. This polygraphic substitution cipher makes it … See more As an example of the Hill Cipher technique, let’s encrypt the text, ‘ACT’, and, later, decrypt the resulting ciphertext. This will help us understand … See more When dealing with 2×2 matrices, Hill Cipher is easily solvable. But when it comes to modern cryptography solutions that have 256 combinations of numbers, Hill Ciphers can be fairly weak. As mentioned earlier, Hill … See more Following are the main advantages of Hill Cipher: 1. It perfectly conceals single-letter frequencies 2. 3×3 Hill Ciphers are extremely effective when it comes to hiding both single-letter and two-letter frequency … See more
