CCA-Secure Leakage-Resilient Identity-Based Key-Encapsulation from Simple (not $\mathtt{q}$-type) Assumptions
public-key cryptography leakage-resilient identity-based encryption
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...
SAT-attack is known to successfully decrypt a functionally correct key of a locked combinational circuit. It is possible to extend the SAT-attack to sequential circuits through the scan-chain by selec...
Trustless, Censorship-Resilient and Scalable Votings in the Permission-based Blockchain Model
DAO voting functional encryption
2019/6/4
Voting systems are the tool of choice when it comes to settle an agreement of different opinions. We propose a solution for a trustless, censorship-resilient and scalable electronic voting platform. B...
Tight Leakage-Resilient CCA-Security from Quasi-Adaptive Hash Proof System
public-key encryption leakage-resilience CCA security
2019/5/21
We propose the concept of quasi-adaptive hash proof system (QAHPS), where the projection key is allowed to depend on the specific language for which hash values are computed. We formalize leakage-resi...
In the past 15 years, cryptography has made considerable progress in expanding the adversarial attack model to cover side-channel attacks, and has built schemes to provably defend against some of them...
Lower Bounds for Leakage-Resilient Secret Sharing
Lower Bound Secret Sharing Leakage-Resilience
2019/3/1
Threshold secret sharing allows a dealer to split a secret into nn shares such that any authorized subset of cardinality at least tt of those shares efficiently reveals the secret, while at the same t...
TEDT, a Leakage-Resilient AEAD mode for High (Physical) Security Applications
Authenticated encryption re-keying tweakable block cipher
2019/2/26
We propose TEDT, a new Authenticated Encryption with Associated Data (AEAD) mode leveraging Tweakable Block Ciphers (TBCs). TEDT provides the following features: (i) It offers asymptotically optimal s...
Leakage-resilient Identity-based Encryption in Bounded Retrieval Model with Nearly Optimal Leakage-Ratio
Leakage-resilience Bounded retrieval model Identity-based Encryption
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...
Leakage-Resilient Group Signature: Definitions and Constructions
group signature full anonymity full traceability
2019/1/9
Group signature scheme provides group members a way to sign messages without revealing their identities. Anonymity and traceability are two essential properties in a group signature system. However, t...
Stronger Leakage-Resilient and Non-Malleable Secret-Sharing Schemes for General Access Structures
Non-malleable secret sharing Leakage-resilient secret sharing Non-malleable extractors
2018/12/3
In this work we present a collection of compilers that take secret sharing schemes for an arbitrary access structures as input and produce either leakage-resilient or non-malleable secret sharing sche...
A secret sharing scheme allows a dealer to share a secret among a set of nn parties such that any authorized subset of the parties can recover the secret, while any unauthorized subset of the parties ...
Efficient Fully-Leakage Resilient One-More Signature Schemes
leakage resilient signature schemes
2018/11/30
In a recent paper Faonio, Nielsen and Venturi (ICALP 2015) gave new constructions of leakage-resilient signature schemes. The signature schemes proposed remain unforgeable against an adversary leaking...
In this work, we consider the natural goal of designing secret sharing schemes that ensure security against a powerful adaptive adversary who may learn some ``leaked'' information about all the shares...
Strong Leakage Resilient Encryption by Hiding Partial Ciphertext
Leakage Resillient Encryption Steal Resillient Encryption Secret Sharing
2018/11/16
Leakage-resilient encryption is a powerful tool to protect data confidentiality against side channel attacks. In this work, we introduce a new and strong leakage setting to counter backdoor (or trojan...
Public Key Encryption Resilient to Post-Challenge Leakage and Tampering Attacks
After-the-Fact Post-challenge Entropic PKE
2018/11/13
In this paper, we introduce a new framework for constructing public-key encryption (PKE) schemes resilient to joint post-challenge/after-the-fact leakage and tampering attacks in the bounded leakage a...
