Special Section on Secure Computer Architectures

The papers in this special section focus on security in computer architectures. Computer architectures are profoundly affected by a new security landscape, caused by the dramatic evolution of information technology over the past decade. First, secure computer architectures have to support a wide range of security applications that extend well beyond the desktop environment, and that also include handheld, mobile, and embedded architectures, as well as high-end computing servers. Second, secure computer architectures have to support new applications of information security and privacy, as well as new information security standards. Third, secure computer architectures have to be protected and be tamperresistant at multiple abstraction levels, covering network, software, and hardware. This Special Section in Transactions on Computers aims to capture this evolving landscape of secure computing architectures, to build a vision of opportunities and unresolved challenges.
