Encrypted Block Code

Abstract

All coding algorithms including the linear block code provides explicit ways of ensuring that message remains legible even in the presence of errors, but without security. So a modified method to the linear block code that provides both error free and encryption will be present.The information are encoded and encrypted at the same time. The encryption will be done by using both permutation and Hill cipher, while the decryption will be done by using Hill cipher only.
