#### Abstract

Information security is an important issue. Recently many social aspects have developed reliance on networking infrastructures. Health, finance, and many other sectors are using local networks and the global Internet. The security of this infrastructure has been called into a question over the last decade. In particular, how to send data securely?

It is well known that Hash algorithm works in one way and cannot be reversed, we can design a one way hash algorithm by using one of the most famous symmetric cryptosystems since its invention in 1929, which named Hill cipher algorithm. Since Hill cipher requires the inverse of the key matrix for decryption. This inverse not always exists, so we can use non-invertible matrices. to propose a model for our new hash algorithm.
