    GCACS-IoD: A certificate based generic access control scheme for Internet of drones
    (ELSEVIER, RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2021) Chaudhry, Shehzad Ashraf; Yahya, Khalid O. Moh.; Karuppiah, Marimuthu; Kharel, Rupak; Bashir, Ali Kashif; Bin Zikria, Yousaf
    Internet of drones (IoD) has gained significant importance in recent times due to its applications in several critical domains ranging from commercial to defense and rescue operations. With several drones flying in different zones to carry out specified tasks, the IoD can be beneficial to gather the real time data for interpretation by the users. However, the data access is carried out through an open channel and battery operated drones. Therefore, the drones’ security and privacy are crucial for accomplishing mission-critical, safety-critical, or surveillance operations. In 2020, Bera et al. presented a certificate based access control scheme for securing the IoD access and argued the scheme’s security through formal and informal methods. However, the analysis presented in this paper shows that the scheme of Bera et al. does not provide anonymity and is insecure against multiple threats, including drone impersonation, the man in the middle, and replay attacks. We then designed a generic certificate based access control scheme to provide inter-drone and drone to ground station access control/authentication in the IoD domain (GCACS-IoD). The GCACS-IoD is provably secure against the known attacks and provides anonymity. GCACS-IoD extends security while preserving computation and communication efficiencies.

    Guest Editorial: Introduction to the special section on security and privacy in the big data era (VSI-spbd)
    (PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2022) Karuppiah, Marimuthu; Chaudhry, Shehzad Ashraf; Alsharif, Mohammed H.
    There is a rising need to secure data in the era of big data. But with the rapid development of technologies such as IoT and cloud computing, users’ security and privacy measures are under tremendous pressure. Big data has led the world to an inflection point in machine learning and analytics, where powerful software tools are able to analyze vast amounts of information and often make better decisions than humans can. A major challenge for preserving privacy in the big data era is that it is hard to anonymize data without losing valuable information. Furthermore, big data has huge potential as a force for good, but numerous security and privacy concerns will dramatically reshape how big data is governed in the years and decades to come. Security, privacy, and related issues have become critical because of the wide applications in many areas.
