Detecting DDoS Attacks in IoT-Based Networks Using Matrix Profile by Mohammed Ali Alzahrani, Ali M. Alzahrani, Muhammad Shoaib Siddiqui

“…However, most of these devices use cheap hardware and lack a concrete security defence system. This may encourage hackers to recruit these devices and use them to launch Distributed Denial of Service (DDoS) attacks, which is one of the main causes of concern among security engineers. …”

Security estimation of LWE via BKW algorithms by Yu Wei, Lei Bi, Xianhui Lu, Kunpeng Wang

“…We introduce the framework and key techniques of BKW algorithms and make comparisons between different BKW algorithms and also with lattice methods by estimating concrete security of specific LWE instances. We also briefly discuss the current problems and potential future directions of BKW algorithms.…”

Security issues and system structure of internet of vehicles by Liang-min WANG, Ting-ting LI, Long CHEN

“…Instead of focusing on concrete security requirements of each IOV applying scenario,the architecture characteristics of the IOV networking systems were summarized,and the main security problems were extracted by analyzing the connotation and network architecture of IOV in different development stages.Then an identity authen-tication based three-tier security architecture over the clearly analyzed concept and structure was proposed,and the related IOV security research with the view of the presented three-tier security architecture were surveyed.Finally,some new developments and progresses over security of IOV were presented.…”

Secure Accelerometer-Based Pairing of Mobile Devices in Multi-Modal Transport by Bogdan Groza, Adriana Berdich, Camil Jichici, Rene Mayrhofer

“…The main goal of our work is to establish the amount of entropy that can be collected from these environments in order to determine concrete security bounds for each environment. We test several signal processing techniques on the extracted data, e.g., low-pass and high-pass filters, then apply sigma-delta modulation in order to expand the size of the feature vectors and increase both the pairing success rate and security level. …”

A Secure and Lightweight Fine-Grained Data Sharing Scheme for Mobile Cloud Computing by Haifeng Li, Caihui Lan, Xingbing Fu, Caifen Wang, Fagen Li, He Guo

“…Different from the current schemes, our novel scheme can enjoy the following promising merits simultaneously: (1) Supporting verifiable outsourced decryption, i.e., the mobile user can ensure the validity of the transformed ciphertext returned from the cloud server; (2) resisting decryption key exposure, i.e., our proposed scheme can outsource decryption for intensive computing tasks during the decryption phase without revealing the user’s data or decryption key; (3) achieving a CCA security level; thus, our novel scheme can be applied to the scenarios with higher security level requirement. The concrete security proof and performance analysis illustrate that our novel scheme is proven secure and suitable for the mobile cloud computing environment.…”
