Webreason, as the dimension of the key matrix increases, the more secure the Hill Cypher becomes. For perspective, for an NxN matrix using our encryption example, there are 26𝑁2 possibilities. So, for a 2x2 matrix, that provides over 456,000 unique matrices, while a simple increase to a 3x3 matrix can provide of 5 trillion unique matrices. WebThe hill cipher is a method of encryption invented in 1929 by Lester S. Hill. When they were invented they were the most practical polygraphic substitution cipher because the …

WebEncryption. First, we need to turn the keyword into a matrix. Any size matrix can be used, as long as it results in a box (for example, 2x2 or 3x3). For this example we will use a 3x3 matrix. When creating the matrix, use numbers under 26 (representing letters in the english alphabet). So now we have our matrix key.
