The security of a digital system depends directly on the security of the hardware platform the system is based on. The analysis of currently available computer architectures has shown that such systems offer a lot of security gaps. This is due to the fact that in the past hardware has only been optimized for speed - never for security. In this paper we propose a set of hardware features to support...
Version 2 of IEEE 1588 contains an extension to secure the given service of clock synchronization. This article describes a practical implementation of this extension for a clock synchronization network. Pitfalls also relevant to other implementations and important properties are discussed and performance results that cover normal operation and stress tests such as denial of service attacks are presented...
We present the design of a trusted platform module (TPM) that supports hardware-based virtualization techniques. Our approach enables multiple virtual machines to use the complete power of a hardware TPM by providing for every virtual machine (VM) the illusion that it has its own hardware TPM. For this purpose, we introduce an additional privilege level that is only used by a virtual machine monitor...
