In symmetric key algorithm in linear block cipher to encrypt and decrypt the messages using matrix and inverse matrix.In this proposed technique generate lower and upper triangular matrices from square matrix using decomposition.In encryption process, the key is lower triangular matrix and decryption process, the key is upper triangular matrix under modulation of prime number.We illustrate the proposed technique with help of examples.
