Abstract
The Dyad project at Carnegie Mellon University is using physically secure coprocessors to achieve new protocols and systems addressing a number of perplexing security problems. These coprocessors can be produced as boards or integrated circuit chips and can be directly inserted in standard workstations or PC-style computers. This paper presents a set of security problems and easily implementable solutions that exploit the power of physically secure coprocessors: (1) protecting the integrity of publicly accessible workstations, (2) tamper-proof accounting/audit trails, (3) copy protection, and (4) electronic currency without centralized servers. We outline the architectural requirements for the use of secure coprocessors. 1 Introduction and Motivation The Dyad project at Carnegie Mellon University is using physically secure coprocessors to achieve new protocols and systems addressing a number of perplexing security problems. These coprocessors can be produced as boards or integrated ...
