  Coding/decoding algorithms are of great importance to help in improving
information security since information security is a more significiant problem
in recent years. In this paper we introduce two new coding/decoding algorithms
using Fibonacci $Q$-matrices and $R$-matrices. Our models are based on the
blocked message matrices and the encryption of each message matrix with
different keys. These new algorithms will not only increase the security of
information but also has high correct ability.
