On Private-Key Cryptosystems Based on Product Codes

Recently J. and R.M. Campello de Souza proposed a private-key encryption scheme based on the product codes with the capability of correcting a special type of structured errors. In this paper, we show that J. and R.M. Campello de Souza's scheme is insecure against chosen-plaintext attacks, and consequently propose a secure modified scheme.
