SummaryCloud computing is an emerging paradigm that enables on‐demand data storage without considering the local infrastructure limitations of end‐users. The extensive growth in number of servers, resources, and networks intensifies security and privacy concerns in clouds. This necessitates secure mutual authentication and key agreement mechanism to verify the legitimacy of participating entities. In accordance, several authentication protocols have been designed to authenticate end‐users over insecure channels. This article presents security analysis of recent protocols that claim to render security and privacy features. We demonstrate that Kaur et al.'s protocol is vulnerable to replay attack, Dharminder et al.'s protocol is prone to user traceability and known session‐specific temporary information (KSSTI) attacks, and Bouchaala et al.'s protocol is prone to replay and KSSTI attacks. To withstand the aforementioned attacks, we propose an enhanced protocol based on fuzzy verifier and elliptic curve cryptography for clouds. Our protocol safeguards against security attacks while providing privacy functionalities. The security analysis is illustrated under real‐or‐random model, and correctness is verified under the Scyther security verification tool. Finally, comparative analysis with existing protocols shows that our protocol delivers robust security with reasonable computational and communication overheads than state‐of‐the‐art protocols.

educing energy consumption is a pressing issueeducing energy consumption is a pressing issueR in low-power machine-type communication (MTC) networks. In this regard, the Wake-up Signal (WuS) technology, which aims to minimize the energy consumed by the radio interface of the machine-type devices (MTDs), stands as a promising solution. However, stateof-the-art WuS mechanisms use static operational parameters, so they cannot efficiently adapt to the system dynamics. To overcome this, we design a simple but efficient neural network to predict MTC traffic patterns and configure WuS accordingly. Our proposed forecasting WuS (FWuS) leverages an accurate long-short term memory (LSTM)-based traffic prediction that allows extending the sleep time of MTDs by avoiding frequent page monitoring occasions in idle state. Simulation results show the effectiveness of our approach. The traffic prediction errors are shown to be below 4%, being false alarm and miss-detection probabilities respectively below 8.8% and 1.3%. In terms of energy consumption reduction, FWuS can outperform the best benchmark mechanism in up to 32%. Finally, we certify the ability of FWuS to dynamically adapt to traffic density changes, promoting low-power MTC scalability.

“…In certain communication scenarios, such as high-speed trains, convoys, and buses, multiple MTC devices (MTCDs) may move from the coverage area of one base station to another. This occurrence is labeled as a "group handover", necessitating each MTCD to authenticate during the transition [1].…”

In the realm of the fifth-generation (5G) wireless cellular networks, renowned for their dense connectivity, there lies a substantial facilitation of a myriad of Internet of Things (IoT) applications, which can be supported by the massive machine-type communication (MTC) technique, a fundamental communication framework. In some scenarios, a large number of machine-type communication devices (MTCD) may simultaneously enter the communication coverage of a target base station. However, the current handover mechanism specified by the 3rd Generation Partnership Project (3GPP) Release 16 incurs high signaling overhead within the access and core networks, which may have negative impacts on network efficiency. Additionally, other existing solutions are vulnerable to malicious attacks such as Denial of Service (DoS), Distributed Denial of Service (DDoS) attacks, and the failure of Key Forward Secrecy (KFS). To address this challenge, this paper proposes an efficient and secure handover authentication protocol for a group of MTCDs supported by blockchain technology. This protocol leverages the decentralized nature of blockchain technology and combines it with certificateless aggregate signatures to mutually authenticate the identity of a base station and a group of MTCDs. This approach can reduce signaling overhead and avoid key escrow while significantly lowering the risk associated with single points of failure. Additionally, the protocol protects device anonymity by encrypting device identities with temporary anonymous identity markers with the Elliptic Curve Diffie–Hellman (ECDH) to abandon serial numbers to prevent linkage attacks. The resilience of the proposed protocol against predominant malicious attacks has been rigorously validated through the application of the BAN logic and Scyther tool, underscoring its robust security attributes. Furthermore, compared to the existing solutions, the proposed protocol significantly reduces the authentication cost for a group of MTCDs during handover, while ensuring security, demonstrating commendable efficiency.
