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 process is simple and can be used on more than three symbols, which was a unique attribute at the time. However, they never gained much popularity because even though they ...

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.
