    A secure demand response management authentication scheme for smart grid
    (ELSEVIER, RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2021) Irshad, Azeem; Chaudhry, Shehzad Ashraf; Alazab, Mamoun; Kanwal, Ambrina; Zia, Muhammad Sultan; Bin Zikria, Yousaf
    The electricity demands are floated through smart grid (SG) devices to a remote power management system and utility center (UC) for utilizing energy-based services, while the UCs manage the distribution of power. Nevertheless, in smart grid systems, the communication messages are susceptible to various threats, since the information related to power consumption is communicated over an unsafe public channel. Therefore, a secure authenticated key agreement scheme is crucial for dispensing energy-based services to legal subscribers. In this regard, Yu et al. designed a secure authentication scheme for smart grid-based demand response management. Nevertheless, we discover that Yu et al.’s protocol is prone to replay attack, denial-of-service attack, and many technical defects in the protocol. Thus, we propose an anonymous and lightweight authenticated key agreement protocol for smart grid-based demand response management countering the limitations in Yu et al.’s scheme. Our scheme may withstand known security attacks, and also supports privacy as well as mutual authentication. We evaluate the security properties of contributed protocol employing informal security analysis and proved the security of session key between the utility center and smart grid using Burrows Abadi Needham (BAN) logic analysis and ProVerif automated simulation. The achieved results sufficiently advocate the practical implementation of the scheme.

    Sixth Generation (6G) Wireless Networks: Vision, Research Activities, Challenges and Potential Solutions
    (MDPI, ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND, 2020) Alsharif, Mohammed H.; Kelechi, Anabi Hilary; Albreem, Mahmoud A. M.; Chaudhry, Shehzad Ashraf; Zia, Muhammad Sultan; Kim, Sunghwan
    The standardization activities of the fifth generation communications are clearly over and deployment has commenced globally. To sustain the competitive edge of wireless networks, industrial and academia synergy have begun to conceptualize the next generation of wireless communication systems (namely, sixth generation, (6G)) aimed at laying the foundation for the stratification of the communication needs of the 2030s. In support of this vision, this study highlights the most promising lines of research from the recent literature in common directions for the 6G project. Its core contribution involves exploring the critical issues and key potential features of 6G communications, including: (i) vision and key features; (ii) challenges and potential solutions; and (iii) research activities. These controversial research topics were profoundly examined in relation to the motivation of their various sub-domains to achieve a precise, concrete, and concise conclusion. Thus, this article will contribute significantly to opening new horizons for future research directions.
