Building a high-performance, programmable secure coprocessor
Secure coprocessors enable secure distributed applications by providing safe havens where an application program can execute (and accumulate state), free of observation and interference by an adversary with direct physical access to the device. However, for these coprocessors to be effective, participants in such applications must be able to verify that they are interacting with an authentic pr...
متن کاملUsing a High-Performance, Programmable Secure Coprocessor
Unsecure computational environments threaten many nancial cryptography implementations, and other sensitive computation. High-performance secure coprocessors can address these threats. However, using this technology for practical security solutions requires overcoming numerous technical and business obstacles. These obstacles motivate building a high-performance secure coprocessor that balances...
متن کاملValidating a High-Performance, Programmable Secure Coprocessor
This paper details our experiences with successfully validating a trusted device at FIPS 140-1 Level 4—earning the world’s first certificate at this highest level. Over the last several years, our group designed and built a physically secure PCI card (the IBM 4758 [5]) containing a general-purpose processor with crypto support. However, for this device to function as a trusted platform for secu...
متن کاملApplication Support Architecture for a High-Performance, Programmable Secure Coprocessor
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 boundary. With the appropriate application so...
متن کاملBuilding the IBM 4758 Secure Coprocessor
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, Citadel, and 4755 work. We wanted to provide ...
