“…In 2015, Malhi et al [29] showed a CL-AS scheme for vehicular ad hoc networks. Kumar et al [30] found the security loophole of Malhi et al 's scheme and gave an improvement scheme. However, Yang et al [31] indicated that the improvement scheme is still insecure, and they proposed a new improvement scheme.…”

Certificateless aggregate signatures aggregate signatures from different users into one signature. Therefore, a verifier can judge whether all signatures are valid by verifying once. With this advantage, certificateless aggregate signatures are widely used in the environment of limited computing resources. Recently, a novel certificateless aggregate signature scheme was proposed by Kumar et al. This scheme's security was claimed to be secure against two types of attackers under the random oracle model. In this paper, we indicate that their scheme is unable to achieve this security goal. We show an attack algorithm that the second type of attacker could forge a valid signature under an identity without the private key of the target user. Moreover, we demonstrate that the second type of attacker could forge a valid aggregate signature.

“…Lots of existing studies on the CPPA schemes in VANETs have been carried out in recent years. We can broadly categorize these schemes into public key infrastructure-based (PKI-based) schemes [ 1 ], identity-based (ID-based) schemes [ 11 ], and certificateless schemes [ 12 , 13 , 14 , 15 ].…”

“…Despite having solved the key escrow problem in ID-based schemes and the public key certification management problem in PKI-based schemes, the certificateless schemes are still unsuitable for the VANETs. The reason is that such schemes [ 12 , 13 , 14 , 15 ] have poor performances due to the requirements of map-to-point hash and bilinear pairing operations. Compared to other cryptographic operations, these two operations are complex and time-consuming.…”

“… The performance in computation and communication cost is evaluated through quantitative calculations. Experimental results depict that PCPA is more efficient than other schemes in [ 12 , 13 , 14 , 15 ]. An extensive simulation is performed and the results display that PCPA is more feasible and achieves the low average message delay and message loss ratio.…”

Vehicle ad hoc networks (VANETs) is a promising network scenario for greatly improving traffic efficiency and safety, in which smart vehicles can communicate with other vehicles or roadside units. For the availability of VANETs, it is very important to deal with the security and privacy problems for VANETs. In this paper, based on certificateless cryptography and elliptic curve cryptography, we present a certificateless signature with message recovery (CLS-MR), which we believe are of independent interest. Then, a practical certificateless conditional privacy preserving authentication (PCPA) scheme is proposed by incorporating the proposed CLS-MR scheme. Furthermore, the security analysis shows that PCPA satisfies all security and privacy requirements. The evaluation results indicate that PCPA achieves low computation and communication costs because there is no need to use the bilinear pairing and map-to-point hash operations. Moreover, extensive simulations show that PCPA is feasible and achieves prominent performances in terms of message delay and message loss ratio, and thus is more suitable for the deployment and adoption of VANETs.
