“…In the same context as IEEE 802.22, the European Computer Manufacturers Association (ECMA)-392 workgroup aims at designing mechanisms to enable wireless devices to exploit the white spaces in the television frequency bands. Soto and Nogueira [17] state that, despite recently proposed protocols, architectures, and standards already including security (e.g., see IEEE 802.11 SCMP in Section 1.4), they use conventional techniques that are not sufficient to prevent CR networks from the attacks described in this survey. We also believe that reviewing existing limitations in normalization activities, such as FCC specifying that no modifications are allowed on primary networks, can contribute to make identifying PU emulation attacks less challenging, even when PUs are mobile and not known a priori.…”

“…Other than the employment of classic cryptographic approaches to support security mechanisms designed for CR environments, we may note that the most important challenges to research and standardization work regarding security reside in the design of security solutions to cope with the threats that are inherent to the cognitive nature of such environments, as previously discussed [17]. Such threats may potentially challenge the main goal of CR, which is the usage of the available radio spectrum space in a fair and optimal way, while preserving primary or incumbent transmitters from interferences.…”

Currently, there are several ongoing efforts for the definition of new regulation policies, paradigms, and technologies aiming a more efficient usage of the radio spectrum. In this context, cognitive radio (CR) emerges as one of the most promising players by enabling the dynamic access to vacant frequency bands on a non-interference basis. However, the intrinsic characteristic of CR opens new ways for attackers, namely in the context of the effective detection of incumbent or primary users (PUs), the most fundamental and challenging requirement for the successful operation of CR networks. In this article, we provide a global and integrated vision of the main threats affecting CR environments in the context of the detection of primary users, with a particular focus on spectrum sensing data falsification and primary user emulation attacks. We also address solutions and research challenges still required to address such threats. Our discussion aims at being complete and self-contained, while also targeting readers with no specific background on this important topic of CR environments. It is, as far as our knowledge goes, the first work providing a global and clear vision of security threats and countermeasures in the context of primary user detection in CR.

“…Hence, this section focuses on highlighting the importance of resilience in the context of UbiComp systems. We overview the state-of-the-art regarding to resilience in the UbiComp systems and point out future directions for research and innovation [135][136][137][138]. We also understand that resilience in these systems still requires a lot of investigations, however we believe that it was our role to raise this point to discussion through this article.…”

Decades went by since Mark Weiser published his influential work on the computer of the 21st century. Over the years, some of the UbiComp features presented in that paper have been gradually adopted by industry players in the technology market. While this technological evolution resulted in many benefits to our society, it has also posed, along the way, countless challenges that we have yet to surpass. In this paper, we address major challenges from areas that most afflict the UbiComp revolution: 1. Software Protection: weakly typed languages, polyglot software, and networked embedded systems. 2. Long-term Security: recent advances in cryptanalysis and quantum attacks. 3. Cryptography Engineering: lightweight cryptosystems and their secure implementation. 4. Resilience: issues related to service availability and the paramount role of resilience. 5. Identity Management: requirements to identity management with invisibility. 6. Privacy Implications: sensitivity data identification and regulation. 7. Forensics: trustworthy evidence from the synergy of digital and physical world. We point out directions towards the solutions of those problems and claim that if we get all this right, we will turn the science fiction of UbiComp into science fact.

“…The problem of network-failure resilience and its correlated concepts (such as survivability and fault-tolerance) have been addressed in a number of studies in the last few years, within the context of wireless ad hoc networks. The causes of these failures include the following: hardware/software faults, operator errors, malicious or selfish attacks, and natural disasters [10,14,15]. In a nutshell, when an attempt is made to tackle the problem of resilience in wireless ad hoc networks, the main focus is on connectivity management restoring a physical topology [14], providing redundancy [16,17] or applying technologies that can opportunistically use radio spectrum frequency [15].…”

VANET has attracted a good deal of attention owing to its wide range of important applications. VANET is a special kind of mobile ad hoc network, in which most of the nodes are spatio-temporally volatile fast-moving vehicles. Hence, it is extremely difficult to provide resilient end-to-end communications in VANET, although it is a cornerstone for the wider deployment of VANET applications. In VANET, the network and upper layers often fail due to frequent link disruptions caused by the highly dynamic environment. In view of this, we propose MOCA, a M echanism for cOnnectivity management in C ognitive vehiculAr networks, which make use of cognitive radio (CR) technology, to overcome frequent link disruptions and achieve greater resilience for end-to-end data delivery. MOCA benefits from the flexibility and adaptability of CR, which opportunistically accesses the best available licensed channel frequencies. The selection of the best available links is determined by values from observable parameters related to channels and nearby vehicles, such as bit error rate (BER), node speed and driving direction, as well as on the unique application requirements. As the VANET environment can be highly dynamic, MOCA carries out a periodic re-evaluation of the quality of the available channels. Our simulation results show that MOCA outperforms all the other representative alternatives in the literature in terms of throughput and jitter. To the best of our knowledge, MOCA is the first application-independent strategy to provide VANET with resilient end-to-end communications.
