摘要：
In this paper we have modified the Hill cipher by using linear congruences. In this analysis we have two secret keys: (1) the key matrix, and (2) the key involving the constants occurring in the linear congruences. These two keys are termed as outer key and inner key respectively. From the cryptanalysis carried out in this paper, we have found that the inner key plays a very significant role in strengthening the cipher..
