The aim of this paper is to introduce a new encryption algorithm involving byte rotation and invertible matrix. In the proposed algorithm firstly we apply byte rotation to get an intermediate cipher and then applying the invertible matrix (modulo 27), which gives the final cipher text. Using secret key matrix along with congruence modulo, the message can be encrypted and decrypted perfectly.
