在网络隐私保护方面，如何为多媒体移动通信提供安全保障是一个备受关注的问题。其特点是对大量的图像数据进行功率敏感的高速加密。这样的需求应该由一个单一的VLSI处理器系统来满足。本文介绍了一种硬件安全嵌入式多媒体移动处理器HSgorilla。它们是单处理器SMT（同步多线程）、VLIW（超长指令字）、波管道、Java和随机寻址。从运行时间和安全强度的角度来看，HSgorilla实现的RAC（随机寻址密码）与常规密码操作相比是非常有前途的。仔细考虑RAC图像加密的特点，它在普适计算时代是一种非常有前途的技术。
With respect to privacy on the Internet, it is a matter of keen interest to provision security for multimedia mobile communication. This is characterized by the power conscious high speed cryptography of large quantities of image data. Such demand should be covered by a single VLSI processor system. We describe in this article a hardware security-embedded multimedia mobile processor named HSgorilla by sophisticatedly unifying five up-to-date processor techniques. They are single processor SMT (simultaneous multithreading), VLIW (very long instruction word), wave-pipeline, Java, and random addressing. RAC (random addressing cryptography) achieved by HSgorilla is very promising compared with regular cryptographic operations in view of running time and security strength. Carefully considering the features of image cryptography by RAC, it is a very promising technique in the era of ubiquitous computing.
