A generalization of the RSA “elatrash scheme”

الملخص EN

The RSA scheme is a block cipher in which the plaintext and ciphertext are integers between 0 and (n–1) for some n where n a product of two primes.

In this paper, we generalize RSA scheme in order to be applied to general linear group over the ring of integers modulo n and plaintexts and ciphertexts are k×k square matrices with entries in Zn (the integers modulo n) denoted by GL(k, Zn).

We call it “Elatrash scheme”.
