Secure and Efficient Personalized Multi-Receiver Data Sharing With Cross-Domain Authentication for Internet of Vehicles

This research paper proposes a new cryptographic method for secure data sharing in Internet of Vehicles (IoV, a system where vehicles communicate with each other and road infrastructure). The method uses Certificateless Signcryption (CLSC, a technique that encrypts data and verifies its authenticity without requiring traditional certificates) to allow one sender to securely share customized data with multiple specific receivers while keeping it hidden from others, even across different geographic regions. The proposed approach reduces computational complexity and includes privacy protections through pseudonym generation (creating fake identities).
