Quantum-secure message authentication via blind-unforgeability
Formulating and designing authentication of classical messages in the presence of adversaries with quantum query access has been a longstanding challenge, as the familiar classical notions of unforgeability do not directly translate into meaningful

This paper presents a lightweight mutual authentication protocol for VANETs that integrates SDN, edge computing, and ECC to achieve low‐latency, scalable, and privacy‐preserving vehicle communication. The proposed system reduces authentication delay and computational overhead while supporting batch verification and conditional identity traceability ...

Token‐Guided Flow Tracing for Auditable Zero‐Knowledge Smart Contract Transfers
Private transfers on public smart contract blockchains hide transaction values and private transfer links, but accountable privacy requires controlled auditability. Existing auditable zero‐knowledge transfer systems make per‐transaction audit information available to an authorized auditor, but their audit model may allow the auditor to inspect ...

Two‐Party Adaptor Signature: New Definition and Efficient Constructions From ECDSA
Adaptor signature (AS) has gained increasing popularity lately due to its widespread adoption in different Blockchain applications such as atomic swaps and payment channels. Two‐party AS enhances the security of the signing key by splitting it into two parts. Erwig et al.

MPC‐Facilitated Adaptive Security Framework for BFT Protocols
The growing use of blockchain and distributed systems requires Byzantine fault tolerant (BFT) protocols that remain secure under dynamic adversaries. However, existing BFT protocols often rely on static assumptions and lack clear mechanisms to detect and remove malicious or denial‐of‐service (DoS) nodes during execution.

A Group Proxy Signature Scheme Based on Key Matrix
:In order to overcome the problems that the existing group proxy signature schemes do not have strong unforgeability and can not resist collusion attack by proxy themselves, a group proxy signature scheme of resisting collusion attack based on key matrix
