TL;DR: A detailed investigation of key challenges that constitute an efficient RRM framework is presented and an overview with a classification of recent solutions, in terms of decision making, is provided along with the discussion.

TL;DR: This paper argues that in addition to allowing a device to find other appropriate devices with which to interact, while detecting those that are malicious, the proposed probabilistic trust management scheme is also capable of allowing a devices to judge the trustworthiness of another device it interacts with.

TL;DR: A robust user authentication and key agreement scheme suitable for ubiquitous computing environments and can preserve the privacy of the client's secret key even if the secret information stored in a smart card is compromised.

TL;DR: A novel form of centrality is introduced: the second order centrality which can be computed in a distributed manner which provides locally each node with a value reflecting its relative criticity and relies on a random walk visiting the network in an unbiased fashion.

TL;DR: A robust and efficient authentication scheme based on strong-password approach to provide secure remote access in digital home network environments and it can be validated that the proposed scheme is more robust authentication mechanism having better security properties.

TL;DR: This paper proposes a new approach for detecting and clustering botnet traffic on large-scale network application communities, in which a novel decision tree model is used to classify those traffic to be unknown by the payload content into known application communities.

TL;DR: This study demonstrates that Chen et al.'s RFID authentication scheme does not provide location privacy and suffers from replay attacks, and an improved scheme is also proposed which can prevent possible attacks and be applied in environments requiring a high level of security.

TL;DR: The power consumption of base stations for mobileWiMAX, fixed WiMAX, UMTS, HSPA, and LTE is modelled and related to the coverage, and the influence of MIMO is investigated.

TL;DR: This work does the statistic work on vulnerabilities of three famous vulnerability databases and analyzes the distribution of vulnerabilities to expose the differences among different vulnerability rating systems, and proposes VRSS for qualitative rating and quantitative scoring vulnerabilities, which can combine respective advantages of all kinds ofulnerability rating systems.

TL;DR: In this paper, the authors proposed an Android/OSGi platform for vehicular telematics applications, which includes remote management, rich class-sharing, proprietary vehicular applications, security policies, easy management of Application Programming Interface (APIs), and an open environment.
