Revisiting the Security of the Lightweight Stream Cipher Draco: New Observation and TMDTO Attacks
Draco is a lightweight small‐state stream cipher proposed in 2022. It is designed to provide a 128‐bit security level and be provably secure against time‐memory‐data trade‐off (TMDTO) attacks. In this paper, we revisit the security of Draco against TMDTO attacks.

Asymmetric cryptography and practical security
Since the appearance of public-key cryptography in Diffie-Hellman seminal paper, many schemes have been proposed, but many have been broken. Indeed, for many people, the simple fact that a cryptographic algorithm withstands cryptanalytic attacks for ...

This paper addresses the limitations of existing conditional privacy‐preserving authentication (CPPA) schemes in vehicular ad hoc networks (VANETs), which are either computationally heavy or vulnerable to quantum attacks. It proposes a multi‐aggregator lattice‐based CPPA (MA‐LCPPA) framework that distributes verification across multiple roadside units ...

Directed acyclic graph (DAG)‐based blockchain is a promising paradigm of a blockchain system. During DAG‐based consensus processes, nodes generate blocks in parallel, as well as voting YES on the previous blocks. It makes the DAG‐based blockchain a performance advantage in terms of confirmation delay and transaction throughput.

Design and Development of a Blockchain‐Enabled Decentralized Framework for Academic Microcredentials
Traditional higher education faces significant challenges, including rising costs, inflexibility, and a disconnect from workforce demands, while current credentialing systems are often centralized and vulnerable to fraud. Microcredentials have emerged as a solution, yet they lack integration into formal degree pathways and face issues with recognition ...
