"In the digital world today, the multimedia security becomes more important. Digital services such as Pay-TV, video conferencing, medical imaging systems, have need of consistent security in storage and communication of multimedia data. It is difficult to use the conventional algorithms such as DES and AES, directly in multimedia data, since multimedia data are repeatedly have high redundancy, large-volumes, and require real-time operations, such as displaying, cutting, copying, bit-rate conversion, and so forth. This paper proposes an encryption algorithm for multimedia data, based on arithmetic modulo."
