… In this paper, the Aggregate Certificateless Signature Scheme is proposed as aggregate
signatures have the advantage of verifying all the signatures received from the other vehicles …

… In summary, the followings are the important contributions of this work: (1) we devise an
efficient V2R authentication scheme based on an anonymous signature scheme, which prevents …

… of ad hoc group signature. This new notion bridges the gap between the ring signature and
group signature schemes. It … it by DKNS scheme and our ad hoc group signature scheme with …

… In this paper, the scheme was analyzed and found to be insecure under existing … signature
scheme for VANETs applications based on elliptic curve cryptography. The proposed scheme …

… It is followed by the description of the security model of a LSAG signature scheme in Sec. 3.
Our LSAG signature scheme is then described in Sec. 4 and the security analysis is given in …

… cut the length of signature, certificateless aggregate signature (CL-AS) is used to achieve
improved performance in resource-constrained environments like vehicular ad hoc networks (…

… In order to cope up with such attacks, various efficient signature schemes have been … by
proposing a blind signature scheme in a certificateless setting. The scheme does not require …

… The proposed signature scheme only requires a general one-way hash function, which
consumes less computing time than a special one-way hash function (MapToPoint). …

… -preserving certificateless public key signature scheme based on the blockchain. Firstly,
our scheme provides support for batch verification and aggregation of the signatures, and has …

… makes traditional signature schemes are not suitable for VANETs. Identity-based signature
can … However, there is a key escrow problem in identity-based signature schemes. That is, a …
