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.

多媒体流密码引擎的开发
在处理海量多媒体数据时,日益增长的无处不在的环境对安全性、速度和功耗意识提出了全面的要求。满足这些需求的实用解决方案是具有安全意识、高性能和复杂的单芯片处理器。根据该方案,我们开发了一个由专用处理器HCgorilla组成的硬件加密嵌入式多媒体移动系统。RAC(随机寻址密码)是一种很有前途的密码技术。本文从hcrc中提取RAC的潜在特性,重点开发了一个多媒体流密码引擎。这非常适合于大量多媒体数据的高速安全通信。
