Linux Running on Secure Cryptographic Coprocessor
IBM Research has demonstrated Linux running on the IBM 4758 secure cryptographic coprocessor, a hardware security module. This is the first general purpose operating system (OS) running on a secure coprocessor. The IBM 4758 cryptographic coprocessor is an advanced, tamper-sensing and responding, programmable PCI card. Its specialized cryptographic electronics, along with a microprocessor, memory and random number generator are housed within a tamper-responding environment to provide a highly secure subsystem in which data processing and cryptography can be performed.
