Lattice-based Revocable (Hierarchical) IBE with Decryption Key Exposure Resistance
RIBE DKER
2018/5/11
Revocable identity-based encryption (RIBE) is an extension of IBE that supports a key revocation mechanism; an indispensable feature for practical cryptographic schemes. Due to this extra feature, RIB...
Lattice-based Revocable Identity-based Encryption with Bounded Decryption Key Exposure Resistance
RIBE DKER
2017/4/17
A revocable identity-based encryption (RIBE) scheme, proposed by Boldyreva et al.\ (CCS'08), provides a revocation functionality for managing a number of users dynamically and efficiently. To capture ...
