Privacy of Stateful RFID Systems with Constant Tag Identifiers
RFID scheme security privacy
2019/7/18
There is a major interest in designing RFID schemes based on symmetric-key cryptography and ensuring efficient tag identification. These requirements taken together often lead to a decrease in the deg...
Code Constructions for Physical Unclonable Functions and Biometric Secrecy Systems
Information theoretic security key agreement physical unclonable functions
2019/7/8
The two-terminal key agreement problem with biometric or physical identifiers is considered. Two linear code constructions based on Wyner-Ziv coding are developed. The first construction uses random l...
Two-Party ECDSA from Hash Proof Systems and Efficient Instantiations
threshold cryptography two-party ECDSA
2019/5/21
ECDSA is a widely adopted digital signature standard. Unfortunately, efficient distributed variants of this primitive are notoriously hard to achieve and known solutions often require expensive zero k...
On the Efficiency of Privacy-Preserving Smart Contract Systems
privacy-preserving smart contracts zk-SNARKs UC-security
2019/5/14
Along with blockchain technology, smart contracts have found intense interest in lots of practical applications. A smart contract is a mechanism involving digital assets and some parties, where the pa...
Starkad and Poseidon: New Hash Functions for Zero Knowledge Proof Systems
snark stark bulletproofs
2019/5/13
The area of practical proof systems, like SNARKs, STARKs, or Bulletproofs, is seeing a very dynamic development. Many use-cases of such systems involve, often as their most expensive apart, proving th...

A New Approach to Modelling Centralised Reputation Systems
group signatures direct anonymous attestation reputation systems
2019/5/9
A reputation system assigns a user or item a reputation value which can be used to evaluate trustworthiness. Bl{\"o}mer, Juhnke and Kolb in 2015, and Kaafarani, Katsumata and Solomon in 2018, gave for...
Updatable Anonymous Credentials and Applications to Incentive Systems
anonymity anonymous credentials incentive systems
2019/2/25
In this paper, we introduce updatable anonymous credential systems (UACS) and use them to construct a new privacy-preserving incentive system. In a UACS, a user holding a credential certifying some at...
XMSS and Embedded Systems - XMSS Hardware Accelerators for RISC-V
XMSS hash-based signatures post-quantum cryptography
2019/1/2
We describe a hardware-software co-design for the hash-based post-quantum signature scheme XMSS on a RISC-V embedded processor. We provide software optimizations for the XMSS reference implementation ...
The Jevil family of encryption systems is a novel set of real-world encryption systems based on the promising foundation of witness encryption. The first Jevil encryption systems comprise of Pentomino...
AuthCropper: Authenticated Image Cropper for Privacy Preserving Surveillance Systems
Privacy Authentication Forward-secure signature
2018/12/19
As surveillance systems are popular, the privacy of the recorded video becomes more important. On the other hand, the authenticity of video images should be guaranteed when used as evidence in court. ...
The 3rd Generation Partnership Project (3GPP) recently proposed a standard for 5G telecommunications, containing an identity protection scheme meant to address the long-outstanding privacy problem of ...
Aggregate Cash Systems: A Cryptographic Investigation of Mimblewimble
Mimblewimble Bitcoin commitments
2018/11/2
Mimblewimble is an electronic cash system proposed by an anonymous author in 2016. It combines several privacy-enhancing techniques initially envisioned for Bitcoin, such as Confidential Transactions ...
Issue, Trade, Redeem: Crossing Systems Bounds with Cryptocurrency-Backed Tokens
Bitcoin Ethereum blockchain
2018/7/9
The ecosystem of cryptocurrencies has been steadily growing since the introduction of Bitcoin, the first decentralised digital currency. While the notion of trustless asset exchange lies at the core o...
Fine-Tuning Decentralized Anonymous Payment Systems based on Arguments for Arithmetic Circuit Satisfiability
