White Paper
The multi-core design of the Cell Broadband Engine Architecture (CBEA) presents an interesting opportunity for advancing secure computing. One class of cores on a CBEA chip, the Synergistic Processor Element (SPE), can be put into isolation mode whereby it is physically isolated from the rest of the system. Unlike many other proposed security architectures, this protection does not rely on any software mechanisms. Therefore, the scheme is robust against a compromised operating system or hypervisor, making CBEA uniquely attractive for security, privacy and digital content protection. Furthermore, the first implementation of this architecture, the Cell Broadband Engine (CBE), has produced compelling performance results for widely used cryptographic routines.
