Abstract :
User group key management is a critical task in secure multicast applications of multimedia contents, such as, the Internet TV, pay per view, satellite TV, etc. These keys must be recalculated, encrypted and redistributed when a user is joined or disjoined to a specific group in order to avoid that users which do not belong to a concrete group can access to the contents of that group. This paper presents a high performance dual MicroBlaze System on Chip (SoC) to perform this management as far as possible. This platform aims to reduce the influence of a user join or disjoin in the reception of the multimedia contents by the rest of users.
