In this research, we have developed a large block cipher by modifying the Hill cipher. In this, we have introduced interlacing of the binary bits of the plaintext as the primary concept leading to confusion. This process is strengthened by using iteration. The cryptanalysis and avalanche effect mentioned in this research clearly exhibit the strength of the cipher.
