LECASC: A framework for secure and anonymous e-bidding using lightweight signcryption atop blockchain

This research paper introduces LECASC, a framework designed to make e-bidding (online auction bidding) secure and anonymous using lightweight signcryption (a cryptographic technique that combines encryption and digital signatures) built on blockchain (a distributed ledger technology where transactions are recorded across many computers). The framework aims to protect bidders' identities and ensure the integrity of bids in online auction systems.
