CCA-Secure Leakage-Resilient Identity-Based Key-Encapsulation from Simple (not $\mathtt{q}$-type) Assumptions
public-key cryptography leakage-resilient identity-based encryption
font style='font-size:12px;'>
2019/8/30
In this paper, we propose a new leakage-resilient identity-based encryption (IBE) scheme that is secure against chosen-ciphertext attacks (CCA) in the bounded memory leakage model. It is the first CCA...

2019/8/14
As an extension of identity-based encryption (IBE), revocable hierarchical IBE (RHIBE) supports both key revocation and key delegation simultaneously, which are two important functionalities for crypt...

We design a suite of protocols so that a small tamper-resistant device can be used as a biometric identity document which can be scanned by authorized terminals. We target both strongly secure identif...
A Generic Construction for Revocable Identity-Based Encryption with Subset Difference Methods

2019/3/21
Revocable identity-based encryption (RIBE) is an extension of IBE that supports a key revocation mechanism, which is important when deployed an IBE system in practice. Boneh and Franklin presented the...
Identity-Based Higncryption
Identity-based cryptography Signcryption Identity-concealment
font style='font-size:12px;'>
2019/2/27
After two decades of research on signcryption, recently a new cryptographic primitive, named higncryption, was proposed at ACM CCS'16. Higncryption can be viewed as privacy-enhanced signcryption, whic...
Leakage-resilient Identity-based Encryption in Bounded Retrieval Model with Nearly Optimal Leakage-Ratio
Leakage-resilience Bounded retrieval model Identity-based Encryption
font style='font-size:12px;'>
2019/1/26
We propose new constructions of leakage-resilient public-key encryption (PKE) and identity-based encryption (IBE) schemes in the bounded retrieval model (BRM). In the BRM, adversaries are allowed to o...
Deterministic Identity-Based Encryption from Lattice-Based Programmable Hash Functions with High Min-Entropy
deterministic identity-based encryption adaptively secure auxiliary-input
font style='font-size:12px;'>
2019/1/26
There only exists one deterministic identity-based encryption (DIBE) scheme which is adaptively secure in the auxiliary-input setting, under the learning with errors (LWE) assumption. However, the mas...
Tightly secure hierarchical identity-based encryption

font style='font-size:12px;'>
2019/1/26
We construct the first tightly secure hierarchical identity-based encryption (HIBE) scheme based on standard assumptions, which solves an open problem from Blazy, Kiltz, and Pan (CRYPTO 2014). At the ...
A Revocable Group Signature Scheme with Scalability from Simple Assumptions and Its Application to Identity Management
Group Signatures Anonymity Revocation
font style='font-size:12px;'>
2019/1/26
Group signatures are signatures providing signer anonymity where signers can produce signatures on behalf of the group that they belong to. Although such anonymity is quite attractive considering priv...
Identity-based Broadcast Encryption with Efficient Revocation

2019/1/18
Identity-based broadcast encryption (IBBE) is an effective method to protect the data security and privacy in multi-receiver scenarios, which can make broadcast encryption more practical. This paper f...
