“…The scheme's superior security is demonstrated by rigorous security proofs that are based on the default cryptographic assumption. Cahyadi et al [19] proposed an authentication method with the potential to boost safety, confidentiality, and productivity by employing the certificateless aggregate signature approach to ensure that no private data is divulged during message transmissions from devices onboard the unit. Nath et al [20] proposed a reciprocal authentication technique for group communication in VANET that protects users' privacy without requiring them to establish a direct connection to a central authority.…”

Vehicular networks with Fifth-Generation (5G) are a new form of wireless communication that could greatly benefit society by lowering the number of preventable car accidents and entertaining passengers in a variety of ways. Security threats can compromise the communications transmitted by a vehicle in a vehicular network because of the open nature of these networks. This means that there are potential security and privacy concerns with VANET. Many methods for fixing VANET's issues have been offered recently. Unfortunately, most of them suffer from significant overhead and security concerns such as Sybil attacks. Therefor, this paper proposes a novel fog computing-based lightweight Sybil resistant attacks, called FC-LSR in 5G-enabled vehicular networks. The proposed FC-LSR scheme makes use of Modified Merkle Patricia Trie (MMPT) in conjunction with Merkle Hash Tree (MHT) to securely store the 'current status' values of cars while protecting the anonymity of the data. In the proposed FC-LSR scheme, vehicles inside the same fog server's region are more likely to update their anonymity at the same time and on a regular basis when anonymous expiration is enabled.

“…Proof-of-Concepts Various concepts of CLC-based solutions have been proposed, such as for authentication [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58], aggregated signing [44,[59][60][61][62][63][64], key agreement [65,66], and signcryption [67][68][69][70][71][72][73]. However, common for these proposals is that they have either been tested in a controller lab environment [42,47,48,59,64,74]…”

Cooperative Intelligent Transport Systems (C-ITSs) are an important development for society. C-ITSs enhance road safety, improve traffic efficiency, and promote sustainable transportation through interconnected and intelligent communication between vehicles, infrastructure, and traffic-management systems. Many real-world implementations still consider traditional Public Key Infrastructures (PKI) as the underlying trust model and security control. However, there are challenges with the PKI-based security control from a scalability and revocation perspective. Lately, certificateless cryptography has gained research attention, also in conjunction with C-ITSs, making it a new type of security control to be considered. In this study, we use certificateless cryptography as a candidate to investigate factors affecting decisions (not) to adopt new types of security controls, and study its current gaps, key challenges and possible enablers which can influence the industry. We provide a qualitative study with industry specialists in C-ITSs, combined with a literature analysis of the current state of research in certificateless cryptographic in C-ITS. It was found that only 53% of the current certificateless cryptography literature for C-ITSs in 2022–2023 provide laboratory testing of the protocols, and 0% have testing in real-world settings. However, the trend of research output in the field has been increasing linearly since 2016 with more than eight times as many articles in 2022 compared to 2016. Based on our analysis, using a five-phased Innovation-Decision Model, we found that key reasons affecting adoption are: availability of proof-of-concepts, knowledge beyond current best practices, and a strong buy-in from both stakeholders and standardization bodies.

“…On the one hand, the failure of a centralized institution can bring the entire trading system to a standstill and also bring about a massive leakage of personal information, making it difficult to guarantee the security of the system [6]. On the other hand, compared with cash transactions, financial asset transactions have special data characteristics, and the imitation of data products is indistinguishable [7]. Registration data and transaction data are stored in a centralized database, which makes it easy to forge once the database is attacked, leaving the security of financial consumers and financial institutions unprotected in Internet financial transactions [8].…”

The rise of Industry 5.0 has led to a smarter and more digital way of doing business, but with it comes the issue of user privacy and security. Only when privacy and security issues are addressed, will users be able to transact online with greater peace of mind. Thus, to address the security and privacy problems associated with industry blockchain technology, we propose a privacy protection scheme for online financial transactions based on verifiable ring signatures and blockchain by comparing and combining the unconditional anonymity provided by ring signatures with the high integrity provided by blockchain technology. Firstly, we present an algorithm for verifying ring signature based on distributed key generation, which can ensure the integrity of transaction data. Secondly, by using the block chain technique, we choose the proxy node to send the plaintext message into the block chain, and guarantee the security of the asset transaction. On this basis, the designed scheme is subjected to a security analysis to verify that it is completely anonymous, verifiable and unerasable. The protection of user privacy can be achieved while enabling online transactions. Finally, it is shown that the proposed method is more effective and practical than other similar solutions in performance assessment and simulation. It is proved that the scheme is a safe and efficient online financial transaction ring signature scheme.
