Building 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 ...
متن کاملPseudo-random Number Generation on the IBM 4758 Secure Crypto Coprocessor
In this paper we explore pseudo-random number generation on the IBM 4758 Secure Crypto Coprocessor. In particular we compare several variants of Gennaro's provably secure generator, proposed at Crypto 2000, with more standard techniques based on the SHA-1 compression function. Our results show how the presence of hardware support for modular multiplication and exponentiation aaects these algori...
متن کاملBuilding 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 کاملThe IBM PCIXCC: A new cryptographic coprocessor for the IBM eServer
IBM has designed special cryptographic processors for its servers for more than 25 years. These began as very simple devices, but over time the requirements have become increasingly complex, and there has been a never-ending demand for increased speed. This paper describes the PCIXCC, the new coprocessor introduced in the IBM z990 server. In many ways, PCIXCC is a watershed design. For the firs...
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...
