Development of a Multimedia Stream Cipher Engine

Abstract

Ever growing ubiquitous environment makes overall demands for security, speed, and power consciousness in processing huge amount of multimedia data. A practical solution to meet these demands is a safety aware, high-performed, and sophisticated single chip processor. According to this scheme, we have exploited a hardware cryptography-embedded multimedia mobile system composed of a dedicated processor called HCgorilla. A promising cipher technique conceived from this system is RAC (random addressing cryptography). Abstracting the potential feature of RAC from HCgorilla, we focus in this article the development of a multimedia stream cipher engine. This is really suited to the high speed safety communication of large quantity of multimedia data.
