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. http://ethesis.nitrkl.ac.in/68/1/10307021.pdf
