IAMS framework: a new framework for acceptable user experiences for integrating physical and virtual identity access management systems
The modern world is populated with so many virtual and physical Identity Access Management Systems (IAMSs) that individuals are required to maintain numerous passwords and login credentials. The tedious task of remembering multiple login credentials can be minimised through the utilisation of an innovative approach of single sign-in mechanisms. During recent times, several systems have been developed to provide physical and virtual identity management systems; however, most have not been very successful. Many of the available systems do not provide the feature of virtual access on mobile devices via the internet; this proves to be a limiting factor in the usage of the systems. Physical spaces, such as offices and government entities, are also favourable places for the deployment of interoperable physical and virtual identity management systems, although this area has only been explored to a minimal level. Alongside increasing the level of awareness for the need to deploy interoperable physical and virtual identity management systems, this paper addresses the immediate need to establish clear standards and guidelines for successful integration of the two medium
Multimodal person recognition for human-vehicle interaction
Next-generation vehicles will undoubtedly feature biometric person recognition as part of an effort to improve the driving experience. Today's technology prevents such systems from operating satisfactorily under adverse conditions. A proposed framework for achieving person recognition successfully combines different biometric modalities, borne out in two case studies
Security, user experience, acceptability attributes for the integration of physical and virtual identity access management systems
A number of systems have been developed in the recent history to provide physical and virtual identity management systems; however, most have not been very successful. Furthermore, alongside increasing the level of awareness for the need to deploy interoperable physical and virtual identity management systems, there exists an immediate need for the establishment of clear standards and guidelines for the successful integration of the two mediums. The importance and motivation for the integration of the two mediums is discussed in this paper with respect to three perspectives: Security, which includes identity; User Experience, comprising Usability; and Acceptability, containing Accessibility. Not many systems abide by such guidelines for all of these perspectives; thus, our proposed system (UbIAMS) aims to change this and provide its users with access to their services from any identity access management system rather than merely providing access to a specific set of system
Challenges of Multi-Factor Authentication for Securing Advanced IoT (A-IoT) Applications
The unprecedented proliferation of smart devices together with novel
communication, computing, and control technologies have paved the way for the
Advanced Internet of Things~(A-IoT). This development involves new categories
of capable devices, such as high-end wearables, smart vehicles, and consumer
drones aiming to enable efficient and collaborative utilization within the
Smart City paradigm. While massive deployments of these objects may enrich
people's lives, unauthorized access to the said equipment is potentially
dangerous. Hence, highly-secure human authentication mechanisms have to be
designed. At the same time, human beings desire comfortable interaction with
their owned devices on a daily basis, thus demanding the authentication
procedures to be seamless and user-friendly, mindful of the contemporary urban
dynamics. In response to these unique challenges, this work advocates for the
adoption of multi-factor authentication for A-IoT, such that multiple
heterogeneous methods - both well-established and emerging - are combined
intelligently to grant or deny access reliably. We thus discuss the pros and
cons of various solutions as well as introduce tools to combine the
authentication factors, with an emphasis on challenging Smart City
environments. We finally outline the open questions to shape future research
efforts in this emerging field.Comment: 7 pages, 4 figures, 2 tables. The work has been accepted for

Security and Privacy Issues in Wireless Mesh Networks: A Survey
This book chapter identifies various security threats in wireless mesh
network (WMN). Keeping in mind the critical requirement of security and user
privacy in WMNs, this chapter provides a comprehensive overview of various
possible attacks on different layers of the communication protocol stack for
WMNs and their corresponding defense mechanisms. First, it identifies the
security vulnerabilities in the physical, link, network, transport, application
layers. Furthermore, various possible attacks on the key management protocols,
user authentication and access control protocols, and user privacy preservation
protocols are presented. After enumerating various possible attacks, the
chapter provides a detailed discussion on various existing security mechanisms
and protocols to defend against and wherever possible prevent the possible
attacks. Comparative analyses are also presented on the security schemes with
regards to the cryptographic schemes used, key management strategies deployed,
use of any trusted third party, computation and communication overhead involved
etc. The chapter then presents a brief discussion on various trust management
approaches for WMNs since trust and reputation-based schemes are increasingly
becoming popular for enforcing security in wireless networks. A number of open
problems in security and privacy issues for WMNs are subsequently discussed
before the chapter is finally concluded.Comment: 62 pages, 12 figures, 6 tables. This chapter is an extension of the
author's previous submission in arXiv submission: arXiv:1102.1226. There are
