Product cipher

A product cipher is a cryptographic system that combines two or more different types of ciphers in a way that enhances the security of the encryption process. The basic concept involves using one cipher to encrypt data and then using one or more additional ciphers to further process the data, thereby creating a more complex and secure encryption scheme. The main idea behind a product cipher is that by combining different encryption techniques, the weaknesses of one cipher can be mitigated by the strengths of another.
