MMB, or the MMB cipher, is a symmetric key block cipher that was invented as an alternative to established encryption standards. It was developed by Paul M. B. P. V. Clement and is characterized by its design principles emphasizing simplicity and ease of implementation. The MMB cipher uses a structure similar to other block ciphers and operates on fixed-size blocks of data, providing confidentiality through encryption and decryption processes that involve a secret key.
