The paper estimates the quantum resources required to break 256-bit ECC cryptography and warns that fast-clock quantum computers could enable on-spend attacks on modern cryptocurrencies, necessitating…

MEV-ACE introduces a fair ordering protocol that mitigates proposer-controlled MEV by combining authenticated economic identities, auditable commit/open messages, and verifiable delay randomness to en…

This paper provides the first unified, security-focused survey that rigorously maps Layer-2 (L2) blockchain architecture to its underlying cryptographic security assumptions.

The paper introduces MEV non-interference, a formal security notion, to ensure that composing new smart contracts in DeFi does not increase the maximal extractable value, thereby providing a formal fo…

This paper provides a comprehensive, system-level taxonomy for designing quantum-resistant network architectures, moving beyond simple protocol substitutions to address key distribution and management…

This paper analyzes the x402 payment protocol, revealing systemic vulnerabilities in state synchronization and signature design that allow attackers to exploit payment systems for resource leakage in…

This paper analyzes the x402 payment protocol, revealing critical synchronization and security flaws that allow attackers to exploit payment systems and force merchants to subsidize compute costs.

This paper demonstrates that standard binary kP algorithms, even when protected using Chevallier-Mames atomic blocks, remain vulnerable to single-trace Side-Channel Analysis (SCA) attacks.

The paper analyzes Ethereum builder transactions to show that builder centralization is an emergent property of the Proposer-Builder Separation (PBS) architecture, driven by specific order flow and ME…

This paper quantifies the latency impact of increasing certificate chain sizes required by Post-Quantum Cryptography (PQC) on TLS Time to First Byte (TTFB), finding that Merkle Tree Certificates (MTC)…

The paper proposes a layered, modular network architecture combining Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) to achieve scalable, end-to-end post-quantum security in multi-h…

The paper introduces Search-Bound Proximity Proofs (SBPP) to close an authorization provenance gap in encrypted geographic search by binding zero-knowledge proofs to specific search sessions for audit…

The paper proposes a quantum-resilient session-key establishment scheme that fragments a new key across multiple, independently encrypted Tor circuits, requiring an adversary to compromise many circui…

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 introduces a four-stage structural dependency analysis hierarchy that enables scalable, sound first-order masking verification for large, production-level post-quantum cryptographic accelera…

This paper fixes two subtle bugs in Go's extended GCD implementation, which is critical for RSA key generation, and formally proves the correctness and termination of the corrected code.
