An instruction or a set of instructions can be considered time critical if their execution is required to free up a resource. Time critical instructions might be used to make shared resources such as registers more quickly available for reuse; or they might be used for real time computations, portions of which are critical for the operation of some piece of(More)
This paper gives two simple efficient distributed algorithms: one for keeping clocks in a network synchronized and one for allowing new processors to join the network with their clocks synchronized. The algorithms tolerate both link and node failures of any type. The algorithm for maintaining synchronization will work for arbitrary networks (rather than(More)
Consider a communication network G in which a limited number of link and/or node faults F might occur. A routing &rgr; for the network (a fixed path between each pair of nodes) must be chosen without any knowledge of which components might become faulty. Choosing a good routing corresponds to bounding the diameter of the <italic>surviving route(More)
Security analysis of SERVE 2 Executive Summary This report is a review and critique of computer and communication security issues in the SERVE voting system (Secure Electronic Registration and Voting Experiment), an Internet-based voting system being built for the U.S. Department of Defense's FVAP (Federal Voting Assistance Program).
