WebMar 30, 2024 · 1 Answer. Not necessarily. Consider a Caesar shift cipher on the Roman alphabet of 26 characters. We map the letter to one of the numbers 0-25, say x and add a key value k ∈ [ 0, 25] compute y = x + k mod 26 and then map back to the alphabet. If k is chosen uniformly at random then this is perfectly secure. WebAffine Ciphers Before, when we talked about the Caesar cipher, we used the formula m (mod 26) where m stood for a letter in the alphabet. Now, we will generalize this cipher to mx + y (mod 26) where m stands for a letter in the alphabet (counting from A = 0 to Z= 25) and x,y are any natural number. This is called the Affine cipher.
