“…Furthermore, the authors in [35] showed that the same scheme cannot withstand public key replacement attack and the authors in [36] showed that it cannot withstand the man in the middle attack. In [37], authors achieved superior efficiency to the scheme proposed in [33] by avoiding the use of bilinear pairings, but it was shown that their scheme cannot withstand a malicious KGC attack by [35,38,39]. In [38], a full aggregation pairing-free certificateless scheme was proposed but in [35] it was pointed out that this scheme cannot resist Type I and Type II adversary attacks.…”

“…However, it was shown in [41] that the scheme cannot withstand malicious KGC attack and it was also shown in [42] that the scheme cannot preserve identity privacy. The authors in [30] claimed that their certificateless scheme is more efficient than the one proposed in [40] but it was pointed out in [31,38,39] that the scheme cannot withstand malicious KGC attack. Full aggregation certificateless schemes were also proposed in [31,38,43].…”

Conditional Privacy Preserving Authentication (CPPA) schemes are an effective way of securing communications in Vehicular Adhoc Networks (VANETs), as well as ensuring user privacy and accountability. Cryptanalysis plays a crucial role in pointing out the vulnerabilities in existing schemes to enable the development of more resilient ones. In 2019, Zhang proposed a CPPA scheme for VANET security (PA-CRT), based on identity batch verification (IBV) and Chinese remainder theorem (CRT). In 2023, this scheme was crypt-analyzed by Tao. In this paper we provide our own crypt analysis of Zhang’s scheme and propose counter measures to mitigate Tao’s attacks. Furthermore, in 2021, Xiong proposed a Certificateless Aggregate Signature (CLAS) scheme which was cryptanalyzed by Shim in 2023. Xiong subsequently proposed a modified CLAS scheme which is also cryptanalyzed in this paper.

“…Unfortunately, many of the existing aggregate signature schemes can not resist coalition attacks, which can destroy the aggregate messages' validity and integrity. In recent years, some aggregate signature schemes have been able to resist coalition attacks [13,[33][34][35][36][37]. In 2020, a potential and realistic attack called fully chosen-key attacks was introduced by Wu et al [37].…”

In recent years, deploying Internet of Things (IoT) in electronic healthcare systems (EHS) has made great progress in healthcare detection. It is extremely important to reduce the cost of communication and ensure the authenticity and integrity of data. A linearly homomorphic signature scheme can solve the above problems. However, when the scale of EHS is too large, the transmission, storage and verification of signatures need a high cost. An aggregate signature can combine many signatures generated by many different users into a short one. Therefore, only one aggregate signature needs to be processed during verification, transmission and storage. Combining the advantages of aggregate signature and linearly homomorphic signature, this paper proposes an aggregate signature scheme based on a linearly homomorphic signature for EHS, which has both linear homomorphism and aggregation, and realizes double data compression. Moreover, our scheme can resist a potential real attack, named a coalition attack. The security of this scheme is rigorously demonstrated based on the computational Diffie–Hellman assumption in the random oracle model.

As the power Internet of Things (IoT) enters the security construction stage, the massive use of perception layer devices urgently requires an identity authentication scheme that considers both security and practicality. The existing public key infrastructure (PKI)-based security authentication scheme is currently difficult to apply in many terminals in IoT. Its key distribution and management costs are high, which hinders the development of power IoT security construction. Combined Public Key (CPK) technology uses a small number of seeds to generate unlimited public keys. It is very suitable for identity authentication in the power Internet of Things. In this paper, we propose a novel identity authentication scheme for power IoT. The scheme combines the physical unclonable function (PUF) with improved CPK technology to achieve mutual identity authentication between power IoT terminals and servers. The proposed scheme does not require third-party authentication and improves the security of identity authentication for power IoT. Moreover, the scheme reduces the resource consumption of power IoT devices. The improved CPK algorithm solves the key collision problem, and the third party only needs to save the private key and the public key matrix. Experimental results show that the amount of storage resources occupied in our scheme is small. The proposed scheme is more suitable for the power IoT.
