Abstract

In considering a problem in access control for scalable multimedia formats, we have developed new methods for constructing a key assignment scheme. Our first contribution is to improve an existing cryptographic access control mechanism for scalable multimedia formats. We then show how our methods can be applied to a chain partition to develop alternative mechanisms for scalable multimedia formats and how these methods can themselves be extended to create a new type of key assignment scheme.
