A Case for Tamper-Resistant and Tamper-Evident Computer Systems

Abstract

Recent industrial efforts in architectural and system support for trusted computing still leave systems wide-open even to relatively simple and inexpensive hardware-based attacks. These attacks attempt to snoop or modify data transfer between various chips in a computer system such as between the processor and memory, and between processors in a multiprocessor interconnect network. Software security protection is completely exposed to these attacks because such transfer is managed by hardware without any cryptographic protection. In this paper, we argue that the threats from such attacks are serious and urgent, and that computer design should place a priority in protection against these attacks.
