A novel encryption algorithm for high resolution video
Fuwen Liu, Hartmut Koenig · 2005
The popularity of multimedia applications is rapidly growing nowadays. The confidentiality of video communication is of primary concern for their commercial use, e.g. in video on demand services or in multiparty video conferences. Specific video encryption algorithms are strongly required in real-time multimedia communication to fulfill the strict timing requi-rements. In this paper we present a novel video encryption algorithm, called Puzzle, to encrypt video data in software. It is fast enough to meet real-time demands and provides a sufficient security. The algorithm can readily be incorporated into existing multimedia systems.
