Regarding the design of a multimedia digital content distribution system, the important issues are to supply a large amount of multimedia digital content to users and to guarantee the security of digital content. In this study we proposed designing a security technique for each group in a multilayered structure, and on a caching technique, which is based on this security technique, and to improve the user’s response speed. Using these techniques guarantees the security of digital content distribution.
