product cipher

To increase the security of encrypted messages, the transposition c ipher and the substitution cipher are varied.

By combining both ciphers into a product cipher, the complexity and the security are increased.

Product algorithms are used in the Data Encryption Standard( DES) and the International Data Encryption Algorithm( IDEA), among others. In addition, there is a special group of product algorithms called Feistel networks.
