A " secure system " should be secure—but should also be a system that achieves some particular functionality. A family of secure systems that our group has been investigating (and building) are high-end secure coprocessors: devices that combine a general-purpose computing environment with high-performance cryptography inside a tamper-responding secure(More)
Over the last several years, our research team built a commercially-offered secure coprocessor that, besides other features, offers high-speed DES: over 20 megabytes/second. However, it obtains these speeds only on operations with large data lengths. For DES operations on short data (e.g., 8-80 bytes), our commercial offering was benchmarked at less than 2(More)
W ork leading toward the IBM 4758 started, arguably, in the 1980s when the Abyss project began exploring techniques to build tamper-responsive hardware and use that technology to protect against software piracy. 1,2 Influenced by this earlier work, we sought to build a secure coprocessor, defined as a tamper-responding device derived from the Abyss,(More)
