This paper investigates privacy risks associated with credential disclosure in the upcoming EU Digital Identity Wallet, demonstrating that users tend to overshare information, and proposes a Credentia…

Ciphera proposes a decentralized biometric identity framework that combines facial recognition with DIDs and VCs, achieving feasible sub-second verification while highlighting challenges in revocation…

The paper proposes COD-ssi, a novel framework that achieves mutual privacy in Self-Sovereign Identity (SSI) credential exchanges, ensuring that neither the Holder nor the Verifier can learn unnecessar…

The paper proposes bPk#, a distributed architecture for pseudonyms that enhances privacy and availability in national eID systems by delegating pseudonym computation rights to users and service provid…

The paper introduces the Unicity Execution Layer, a secure, modular component that enables trustless off-chain transactions while guaranteeing double-spending prevention and enhancing user privacy.

This paper analyzes the Loki e-voting protocol, demonstrating that while it attempts to solve coercion-resistance without pre-agreed secrets, it remains vulnerable to specific attacks, suggesting that…

The paper introduces a novel, scalable, and provably secure biometric authentication system designed to authenticate millions of users against cloud databases without requiring auxiliary identifiers.

The paper proposes a canonical, end-to-end validation framework to ensure secure integration of Alternative Data Availability (AltDA) systems with Ethereum Layer 2s, demonstrating that L2 integration…

The paper systematically analyzes 36 existing and proposed digital payment system designs to identify recurring patterns, technical trade-offs, and implementation challenges relevant for future Centra…

BIDO introduces a device-free, NIST AAL2-compliant biometric authentication standard that deterministically generates ephemeral ECDSA keys from live biometric measurements, eliminating the need for st…

The paper introduces PASS, a Provenanced Access Subaccount System that replaces traditional key-based control with verifiable provenance-based control for blockchain wallets, enabling secure, multi-ac…

The paper proves that standard account-based ledgers cannot non-custodially enforce asset disposition, and introduces a novel commitment-based ledger structure, the 'envelope,' that achieves this capa…

The paper proposes a revocation-ready key management layer for blockchain-based IoT data sharing that replaces online key release with ciphertext key publication, enabling local, policy-based decrypti…

The paper proposes a RADIUS-based framework to maintain persistent device identity for Network Access Control (NAC) despite modern operating system MAC address randomization, ensuring regulatory compl…

The paper proposes the User Data Sharing System (UDSS), a hardware-anchored middleware that securely manages PII exchange across diverse consumer electronics devices, significantly reducing onboarding…

SILMARILS presents a quantum-secure, information-theoretic designated-verifier (DV) signature scheme built on a minimal algebraic core, suitable for lightweight blockchain authentication.

The paper introduces the concept of 'authenticity debt'—the institutional liability from deploying unverified AI content—and proposes a layered reference architecture combining cryptographic provenanc…

zk-X509 is a privacy-preserving identity system that uses zero-knowledge proofs to prove ownership of standard X.509 certificates on a public blockchain without revealing private keys or personal data…

The paper analyzes the 'decentralisation paradox' in digital identity, arguing that user-centric designs merely redistribute central control rather than eliminating it, requiring a holistic approach b…
