WebSep 28, 2024 · We will study Hill Cipher encryption and decryption procedures in solving 2×2 and 3×3 matrices. Although it can be used for higher matrices (4×4, 5×5, or 6×6), it also requires a higher and advanced level of mathematics, adding more complexity. Here, we have used simple examples that provide in-depth knowledge on this topic. In classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra. Invented by Lester S. Hill in 1929, it was the first polygraphic cipher in which it was practical (though barely) to operate on more than three symbols at once.
