Security Enhanced CLS and CL-AS Scheme Without Pairings for VANETs

IEEE Access
While vehicle ad-hoc networks (VANETs) have many advantages, they also present privacy and security concerns. Certificate management issues have been seen in traditional public key infrastructure-based privacy-preserving authentication schemes, while key

Comment on New Construction of Efficient Certificateless Aggregate Signatures

International Journal of Security and Its Applications, 2015
Aggregate signature can combine n signatures on n messages from n users into single signature, and the verifier should be convinced by the aggregate signature that n users indeed sign n messages. Since aggregate signature can greatly reduce the length of total signature and the cost of verification, it is widely used in environments with low bandwidth ...

Practical Certificateless Aggregate Signatures From Bilinear Maps

Journal of information science and engineering, 2010
Aggregate signature is a digital signature with a striking property that anyone can aggregate n individual signatures on n different messages which are signed by n distinct signers, into a single compact signature to reduce computational and storage costs.

CSAS-V: Certificateless Schnorr Aggregate Signature for VANETs

International Journal of Innovative Research and Scientific Studies
Efficient message authentication mechanisms for securing vehicular message exchange in VANETs are essential for meeting the diverse needs of real-time communication, driver safety, and data integrity. As such, certificateless aggregate signature (CLAS) schemes are widely used in this area, since they can significantly lower the communication and ...

Practical Certificateless Aggregate Signatures From Bilinear Maps

, 2008
In some restrictive environments, such as sensor networks, each sensor submits the newest information to the server, every message must be authenticated to immune forgery and replay attacks. But the regular signatures need to be saved and verified individually, which will heavily add the costs of the computation, storage and communication than the ...
