Bjorn again
No full textWell they may have lost out on their fair share of the GST, but my friends at the University of Western Australia (UWA) are A$4 million better off thanks to a one-off Federal government grant by the Minister for Education Christoper 'the fixer' Pyne. The grant is to establish a new 'Australia Consensus Centre' at UWA. The consensus among most of my peers is that this was a bad idea. Why? Well first off, the new Centre is a partnership between the Copenhagen Consensus Center and the University of Western Australia. It thus features the Danish academic Bjorn Lomborg, author of the controversial books The Sceptical Environmentalist and Cool It, both of which argue that climate change is not our biggest problem and that we should relax about it (or in Bjorn's terms, 'cool it')

On the Pitfalls and Vulnerabilities of Schedule Randomization against Schedule-Based Attacks
No full textSchedule randomization is one of the recently introduced security defenses against schedule-based attacks, i.e., attacks whose success depends on a particular ordering between the execution window of an attacker and a victim task within the system. It falls into the category of information hiding (as opposed to deterministic isolation-based defenses) and is designed to reduce the attacker’s ability to infer the future schedule. This paper aims to investigate the limitations and vulnerabilities of schedule randomization-based defenses in real-time systems. We first provide definitions, categorization, and examples of schedule-based attacks, and then discuss the challenges of employing schedule randomization in real-time systems. Further, we provide a preliminary security test to determine whether a certain timing relation between the attacker and victim tasks will never happen in systems scheduled by a fixed-priority scheduling algorithm. Finally, we compare fixed-priority scheduling against schedule-randomization techniques in terms of the success rate of various schedule-based attacks for both synthetic and real world applications. Our results show that, in many cases, schedule randomization either has no security benefits or can even increase the success rate of the attacker depending on the priority relation between the attacker and victim tasks.Embedded System
