Authentication Services in Mobile Ad-Hoc Networks
Authentication Services in Mobile Ad-hoc Networks LOgiciels-Réseaux Willy Jiménez 08013 -LOR Hakima Chaouchi Maryline Laurent-Maknavicius _______________________________________________________________________________ Authentication Services in Mobile Ad-hoc Networks ABSTRACT The deployment of wireless ad hoc networks is useful for people when they desire to communicate even if they are not connected to any infrastructure, with the purpose of playing games, sharing internet connection, or exchange files. In some ad hoc scenarios, they might know each other, so they can establish trusted relationships. However, if the number or users and mobility increase then it is more complicated to trust all users and a security mechanism is required. Few researches has been done in this field to find security solutions for MANETs deployments; one of them proposes a framework where the traditional AAA services are distributed inside the network with the idea of allowing secure exchange of services that could be chargeable. Based on this framework, we evaluate technical solutions, focusing mainly on the Authentication service; in order to have real implementations. One possibility is using virtualization technology to offer a de-centralized authentication service. Another solution is the development of a secure version of a routing protocol that uses a de-centralized authentication service as a previous requirement to allow any node to join the ad hoc routing domain.

OPENBSD HARDWARE SENSORS FRAMEWORK a Unified and Ready-To-Use System for Hassle- Ee Hardware Monitoring
OPENBSD HARDWARE SENSORS FRAMEWORK A unified and ready-to-use system for hassle-ee hardware monitoring. Constantine A. Murenin and Raouf Boutaba University of Waterloo AsiaBSDCon 2009 — 12–15 March 2009 — Tokyo, Japan Abstract In this paper, we will discuss the origin, history, design guidelines, API and the device drivers of the hardware sensors framework available in OpenBSD. The framework spans multiple utilities in the base system and the ports tree, is utilised by over 70 drivers, and is considered to be a distinctive and ready-to-use feature that sets OpenBSD apart from many other operating systems, and in its root is inseparable from the OpenBSD experience. 1.

Establishing trusted Machine-to-Machine communications in the Internet of Things through the use of behavioural tests Thesis submitted in accordance with the requirements of the University of Liverpool for the degree of Doctor in Philosophy by Valerio Selis April 2018 \Be less curious about people and more curious about ideas." Marie Curie Abstract Today, the Internet of Things (IoT) is one of the most important emerging technolo- gies. Applicable to several fields, it has the potential to strongly influence people's lives. \Things" are mostly embedded machines, and Machine-to-Machine (M2M) communica- tions are used to exchange information. The main aspect of this type of communication is that a \thing" needs a mechanism to uniquely identify other \things" without human intervention. For this purpose, trust plays a key role. Trust can be incorporated in the smartness of \things" by using mobile \agents". From the study of the IoT ecosystem, a new threat against M2M communications has been identified. This relates to the opportunity for an attacker to employ several forged IoT-embedded machines that can be used to launch attacks. Two \things-aware" detection mechanisms have been proposed and evaluated in this work for incorporation into IoT mobile trust agents. These new mechanisms are based on observing specific thing-related behaviour obtained by using a characterisation algorithm. The first mechanism uses a range of behaviours obtained from real embedded ma- chines, such as threshold values, to detect whether a target machine is forged. This detection mechanism is called machine emulation detection algorithm (MEDA). MEDA takes around 3 minutes to achieve a detection accuracy of 79.21%, with 44.55% of real embedded machines labelled as belonging to forged embedded machines. -

A given ISA may be implemented with different microarchitectures.[1] Implementations might vary due to different goals of a given design or due to shifts in technology.[2] Computer architecture is the combination of microarchitecture and instruction set design. Relation to instruction set architecture The ISA is roughly the same as the programming model of a processor as seen by an assembly language programmer or compiler writer. The ISA includes the execution model, processor registers, address and data formats among other things. The Intel Core microarchitecture microarchitecture includes the constituent parts of the processor and how these interconnect and interoperate to implement the ISA. The microarchitecture of a machine is usually represented as (more or less detailed) diagrams that describe the interconnections of the various microarchitectural elements of the machine, which may be everything from single gates and registers, to complete arithmetic logic units (ALU)s and even larger elements. -
