Efficient Identity-Based Signatures Secure in the Standard Model
The only known construction of identity-based signatures that can be proven secure in the standard model is based on the approach of attaching certificates to non-identity-based si...

Strongly Unforgeable Signatures and Hierarchical Identity-Based Signatures from Lattices without Random Oracles
Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...

Secure Identity Based Encryption Without Random Oracles
We construct two efficient Identity Based Encryption (IBE) systems that are selective identity secure without the random oracle model. Selective identity secure IBE is a slightly w...

Anonymous Hierarchical Identity-Based Encryption (Without Random Oracles)
We present an identity-based cryptosystem that features fully anonymous ciphertexts and hierarchical key delegation. We give a proof of security in the standard model, based on the...

Practical Identity-Based Encryption Without Random Oracles
We present an Identity Based Encryption (IBE) system that is fully secure in the standard model and has several advantages over previous such systems
