The advancing of reverse engineering techniques has complicated the efforts in intellectual property protection. Proactive methods have been developed recently, among which layout-level IC camouflaging is the leading example. However, existing camouflaging methods are rarely supported by provably secure criteria, which further leads to over-estimation of the security level when countering the latest...
Nowadays, electronics systems design is a complex process. A design-and-reuse model has been adopted, and the vast majority of designers integrates third party intellectual property (IP) cores in their design in order to reduce time to market. Due to their immaterial form and high market value, IP cores are exposed to threats such as cloning and illegal copying. In order to fight these threats, we...
Logic obfuscation can protect designs from reverse engineering and IP piracy. In this paper, a new attack strategy based on applying brute force iteratively to each logic cone is described and shown to significantly reduce the number of brute force key combinations that need to be tried by an attacker. It is shown that inserting key gates based on MUXes is an effective approach to increase security...
The paper deals with attack tree-based evaluation of vulnerability. The Attack tree method was originally developed for the purpose of security modeling in the area of information technologies, but gradually it came to spread also in different areas. Particularly in recent years this analytical method has been dynamically developed, and theoretical boundary conditions for its practical application...
Due to globalization of Integrated Circuit (IC) design flow, rogue elements in the supply chain can pirate ICs, overbuild ICs, and insert hardware trojans. EPIC [1] obfuscates the design by randomly inserting additional gates; only a correct key makes the design to produce correct outputs. We demonstrate that an attacker can decipher the obfuscated nctlist, in a time linear to the number of keys,...
The Kolona Gateway is a modular, cross-domain and multilevel security gateway capable of connecting the Global Information Grid (GIG) in a pluggable manner to civilian air traffic management authorities worldwide in a NextGen context. The Kolona On-Time System is a multipurpose container built to NextGen specifications as a framework for the Gateway application. The Kolona On-Time System is: 1. Capable...
Wireless Sensor Networks raise the interest of different business domains, including public security. The ability of WSNs to monitor and control physical environments such as football stadiums makes them very attractive. The integration of WSNs into Command and Control (C2) systems aims at avoiding catastrophes such as the Heysel Stadium disaster. In this paper, the architecture and implementation...
Multi-core SoC created great opportunities to increase overall system performance while keeping the power in check but also created many design challenges that designers must now overcome. The challenge of doubling performance every two years used to drive superscalar design with more functional units running concurrently or deeper pipeline racing for highest frequency at the cost of higher power...
The UNICORE grid system provides a seamless, secure and intuitive access to distributed grid resources. In recent years, UNICORE 5 is used as a well-tested grid middleware system in production grids (e.g. DEISA, D-Grid) and at many supercomputer centers world-wide. Beyond this production usage, UNICORE serves as a solid basis in many European and International research projects and business scenarios...
Information privacy is usually concerned with the confidentiality of personally identifiable information (PII), such as electronic medical records. Nowadays, Web services are used to support different applications which may contain PII, such as healthcare applications. Thus, the information access control mechanism for Web services must be embedded into privacy-enhancing technologies. Further as application...
Internet Relay Chat (IRC) is a critical application in military networks for maintaining situational awareness and conducting battle management at all echelons. But these networks are often subject to frequent disconnections, limited bandwidth, and long delays, especially when using satellite services and field radios. Such conditions are inhospitable to TCP, and thus the standard IRC protocol, which...
This paper discusses the problem of achieving bandwidth and energy-efficient neighborhood group key distributions (NGKD) in tactical wireless sensor networks (TWSNs). We present new techniques that improve NGKD performance while also improving the resilience of TWSNs against attacks that combine node capture with message interception. This is accomplished without introducing additional communications...
