Privacy-preserving auditable token payments in a permissioned blockchain system
cryptographic protocols AML
2019/9/19
Token management systems were the first application of blockchain technology and are still the most widely used one. Early implementations such as Bitcoin or Ethereum provide virtually no privacy beyo...
RAMPARTS: A Programmer-Friendly System for Building Homomorphic Encryption Applications
Homomorphic encryption Automatic arithmetic circuit generation Lattice-based cryptography
2019/9/3
Homomorphic Encryption (HE) is an emerging technnology that enables computing on data while the data is encrypted. A major challenge with homomorphic encryption is that it takes extensive expert knowl...
A hash function family is called correlation intractable if for all sparse relations, it hard to find, given a random function from the family, an input output pair that satisfies the relation. Correl...
Athena: A verifiable, coercion-resistant voting system with linear complexity
cryptographic protocols election schemes
2019/7/8
Seminal work by Juels, Catalano & Jakobsson delivered a verifiable, coercion-resistant voting system with quadratic complexity. This manuscript attempts to advance the state-of-the-art by delivering a...
Design of Anonymous Endorsement System in Hyperledger Fabric
Permissioned Blockchain Hyperledger Fabric Anonymous Endorsement System
2019/6/26
Permissioned Blockchain has become quite popular with enterprises forming consortium since it prioritizes trust over privacy. One of the popular platforms for distributed ledger solution, Hyperledger ...
Improved prover efficiency and SRS size in a Sonic-like system
zk-SNARKs updatable SRS universal SRS
2019/6/3
Using ideas from the recent Aurora zk-STARK of Ben-Sasson et al. [BCRSVW, Eurocrypt 2019], we present a zk-SNARK with a universal and updatable SRS similar to the recent construction of Maller et al. ...
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...
Cryptanalysis of a System Based on Twisted Reed–Solomon Codes
Code-based cryptography McEliece Cryptosystem Subfield Subcodes
2019/4/29
It was recently proved that twisted Reed--Solomon codes represent a family of codes which contain a large amount of MDS codes, non-equivalent to Reed--Solomon codes. As a consequence, they were propos...
PGC: Pretty Good Confidential Transaction System with Accountability
cryptocurrencies confidential transaction accountability
2019/4/1
Due to the public visible nature of blockchain, the seminal cryptocurrencies such as Bitcoin and Ethereum do not provide sufficient level of privacy, i.e., the addresses of sender and receiver and the...
Fully-Featured Anonymous Credentials with Reputation System
Anonymous Credential System Authentication Privacy
2018/11/16
We present CLARCCLARC (Cryptographic Library for Anonymous Reputation and Credentials), an anonymous credentials system (ACS) combined with an anonymous reputation system.
An End-to-End System for Large Scale P2P MPC-as-a-Service and Low-Bandwidth MPC for Weak Participants
cryptographic protocols secure multiparty computation
2018/8/21
Protocols for secure multiparty computation enable a set of parties to compute a joint function of their inputs, while preserving \emph{privacy}, \emph{correctness} and more. In theory, secure computa...
We present Steady: an end-to-end secure logging system engineered to be simple in terms of design, implementation, and assumptions for real-world use. Steady gets its name from being based on a steady...
