This paper discusses the hardware foundations of the cryptosystem employed by the Xbox TM video game console from Microsoft. A secret boot block overlay is buried within a system ASIC. This secret boot block decrypts and verifies portions of an external FLASH-type ROM. The presence of the secret boot block is camouflaged by a decoy boot block in the external ROM. The code contained within the secret boot block is transferred to the CPU in the clear over a set of high-speed busses where it can be extracted using simple custom hardware. The paper concludes with recommendations for improving the Xbox security system. One lesson of this study is that the use of a high-performance bus alone is not a sufficient security measure, given the advent of inexpensive, fast rapid prototyping services and high-performance FPGAs.

Okay, enough of the convoluted history of Java the island and Java the platform. And yes, that is Java, the platform.What began in 1995 as just another programming language is now formally known as a platform. Beginning as a platform-neutral, Internet-friendly development language, Java has evolved into a means of creating programs for just about anything. Let’s step back to the beginning and see how it came about.

Over the last decade, research in parallel architectures has led to many new parallel systems. These systems range from multiprocessors with shared address spaces, multi-computers with distributed address spaces, to networks of high performance workstations. Furthermore, the development of high speed interconnection networks makes it possible to connect the systems together, forming a tremendous computational resource. An effective way to use these machines is to partition a computation into coarse-grain tasks.
