Survey and Systematization of Secure Device Pairing

Secure Device Pairing (SDP) schemes have been developed to facilitate secure communications among smart devices, both personal mobile devices and Internet of Things (IoT) devices. Comparison and assessment of SDP schemes is troublesome, because each scheme makes different assumptions about out-of-band channels and adversary models, and are driven by their particular use-cases. A conceptual model that facilitates meaningful comparison among SDP schemes is missing. We provide such a model. In this article, we survey and analyze a wide range of SDP schemes that are described in the literature, including a number that have been adopted as standards. A system model and consistent terminology for SDP schemes are built on the foundation of this survey, which are then used to classify existing SDP schemes into a taxonomy that, for the first time, enables their meaningful comparison and analysis.The existing SDP schemes are analyzed using this model, revealing common systemic security weaknesses among the surveyed SDP schemes that should become priority areas for future SDP research, such as improving the integration of privacy requirements into the design of SDP schemes. Our results allow SDP scheme designers to create schemes that are more easily comparable with one another, and to assist the prevention of persisting the weaknesses common to the current generation of SDP schemes.Comment: 34 pages, 5 figures, 3 tables, accepted at IEEE Communications Surveys & Tutorials 2017 (Volume: PP, Issue: 99

ANVIA ENTERPRISE WIRELESS LOCAL AREA NETWORK MARKET ANALYZES AND BUSINESS MODEL ENHANCEMENTS.

For almost 15 years, since it has been released, Wi-Fi has been one of the dominant technologies in telecommunication world. However, because of its weaknesses related to security, interference and weak quality of service it has not been accepted as a viable business. Furthermore, it also operates in unlicensed spectrum bands which magnify these issues. On the other hand, technological innovations through new improvements in the world of Wi-Fi have made it one of the most popular indoor communication solutions for enterprises as well as in outdoor common meeting points. Therefore, it has become imperative to study this subject due to its popularity and several issues associated with this technology to create a viable business model for Anvia Oyj. In an attempt to contribute towards this field, present thesis provides a comprehensive theoretical framework that addresses WLAN technology from different aspects including Wi-Fi roaming as well as the description of business model segments. In order to strengthen enterprise WLAN business models, a comprehensive data was collected through different resources. First, an internal interview in Anvia Oyj based on its current enterprise WLAN business model was conducted. Secondly, two surveys were conducted in different enterprise WLAN customer segments; 32 interviews with small office home office (SOHO) enterprises and 10 interviews with SMEs/LEs and municipalities. Thirdly, a global enterprise WLAN market analysis was conducted through Internet resources. Based on these, analyzes, recommendations and business model enhancements are suggested in this thesis. The findings of this research will help Anvia Oyj to achieve better performance in enterprise WLAN business segment.fi=Opinnäytetyö kokotekstinä PDF-muodossa.|en=Thesis fulltext in PDF format.|sv=Lärdomsprov tillgängligt som fulltext i PDF-format

Collaborative Authentication for 6G Networks: An Edge Intelligence based Autonomous Approach

The conventional device authentication of wireless networks usually relies on a security server and centralized process, leading to long latency and risk of single-point of failure. While these challenges might be mitigated by collaborative authentication schemes, their performance remains limited by the rigidity of data collection and aggregated result. They also tend to ignore attacker localization in the collaborative authentication process. To overcome these challenges, a novel collaborative authentication scheme is proposed, where multiple edge devices act as cooperative peers to assist the service provider in distributively authenticating its users by estimating their received signal strength indicator (RSSI) and mobility trajectory (TRA). More explicitly, a distributed learning-based collaborative authentication algorithm is conceived, where the cooperative peers update their authentication models locally, thus the network congestion and response time remain low. Moreover, a situation-aware secure group update algorithm is proposed for autonomously refreshing the set of cooperative peers in the dynamic environment. We also develop an algorithm for localizing a malicious user by the cooperative peers once it is identified. The simulation results demonstrate that the proposed scheme is eminently suitable for both indoor and outdoor communication scenarios, and outperforms some existing benchmark schemes

Policy issues in interconnecting networks

To support the activities of the Federal Research Coordinating Committee (FRICC) in creating an interconnected set of networks to serve the research community, two workshops were held to address the technical support of policy issues that arise when interconnecting such networks. The workshops addressed the required and feasible technologies and architectures that could be used to satisfy the desired policies for interconnection. The results of the workshop are documented
