Abstract:
It is well known that Hash algorithm works in one way, and it
cannot be reversed. We can build a new algorithm by using
Hill cipher technique .Since its invention in 1929, Hill cipher
algorithm which is one of the most famous symmetric
cryptosystems .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, and we proof the four requirements that
needed to design a practical one way hash algorithm.
