An ECDSA Nullifier Scheme and a Proof of Identity Application
ZK-SNARKs (Zero Knowledge Succinct Noninteractive ARguments of Knowledge) are one of the most promising new applied cryptography tools: proofs allow anyone to prove a property about some data, without revealing that data. Largely spurred by the adoption of cryptographic primitives in blockchain …

Two-Party and Threshold ECDSA constructions with bandwidth efficient instantiations from Class Groups of Imaginary Quadratic Fields
ECDSA è uno standard di firma digitale molto utilizzato nella pratica. Per quanto concerne le varianti distribuite di ECDSA, è difficile costruire soluzioni che non richiedano l'utilizzo di dimostrazioni a conoscenza zero costose necessarie a fronteggiare avversari malevoli. In questo manoscritto …

Formally Verifying Secure and Leakage-Free Systems: From Application Specification to Circuit-Level Implementation
… implement and verify several HSMs, including an ECDSA certificate-signing HSM and a password-hashing HSM, on top of Ibex and PicoRV32-based hardware platforms. Parfait provides strong guarantees for these HSMs: for example, it proves that the ECDSA-on-Ibex implementation—2,300 lines of code and …

Energy-harvested Lightweight Cryptosystems
… for Elliptic Curve Digital Signature Algorithm (ECDSA) with different security levels. The implementation of Elliptic Curve Cryptography (ECC) on small microcontrollers is challenging. Most of the earlier literature has considered optimizing the performance of ECC (with respect to cycle count and …

Performance Optimization of Public Key Cryptography on Embedded Platforms
… the Elliptic Curve Digital Signature Algorithm (ECDSA), the Lamport-Diffie one-time hash-based signature scheme (LD-OTS) and the Winternitz one-time hash-based signature scheme (W-OTS). We demonstrate that there’s a trade-off between energy needs, security level and algorithm selection. However, …

Secure Computation in Decentralized Systems
… We develop a highly efficient Threshold ECDSA protocol that runs in the server-aided MPC model. Perhaps more importantly, we revisit the server-aided MPC model itself, which sits somewhere between the dishonest and honest-majority MPC paradigms, and show that a confidential smart contract …

Design and Implementation of PUF Based Protocols for Remote Integrity Verification
In recent years, there has been a drastic increase in the prevalence of counterfeiting within the electronics supply chain. At the same time, high-end commercial off-the-shelf components like FPGAs and expensive peripherals are making their way onto printed circuit boards. Manufacturers of such …
