Identity-Based Hierarchical Key-Insulated Encryption Without Random Oracles
Key-insulated encryption is one of the effective solutions to a key exposure problem. Recently, identity-based encryption (IBE) has been used as one of fundamental cryptographic p...

Identity-Based Cryptosystems and Quadratic Residuosity
Abstract. Three approaches are currently used for devising identitybased encryption schemes. They respectively build on pairings, quadratic residues (QR), and lattices. Among them,...
