Impossibility Results of Card-Based Protocols via Mathematical Optimization
This paper introduces mathematical optimization as a new method for proving impossibility proofs in the field of card-based cryptography. While previous impossibility proofs were often limited to cases involving a small number of cards, this new approach establishes results that hold for a large number of cards. The research focuses on single-cut full-open (SCFO) protocols, which consist of performing one random cut and then revealing all cards. The main contribution is that for any three-varia…

A Lightweight Authentication and Key Agreement Protocol Design for FANET
The advancement of low-altitude intelligent networks enables unmanned aerial vehicle (UAV) interconnection via flying ad-hoc networks (FANETs), offering flexibility and decentralized coordination. However, resource constraints, dynamic topologies, and UAV operations in open environments present significant security and communication challenges. Existing multi-factor and public-key cryptography protocols are vulnerable due to their reliance on stored sensitive information, increasing the risk of…

Open vs. Closed: The Fight for a New Internet
The Story Behind — A federated internet is forming. It's built on open protocols like ActivityPub & connects services like Mastodon, Threads, Pixelfed, Tumblr, Wordpress and more into a connected network known as the fediverse. And everyone from tech enthusiasts to Mark Zuckerberg and Jack Dorsey seem to want in.

Great article on MIDI and a reminder that open protocols won't easily go obsolete once adopted

DeltaChat is a cool idea but should be cranked to the max. Fuck protocols, instant messaging has never been been about the protocol but the network effect.
Not everyone knows how to login to their email outside of the web browser, a chat client should facilitate speech between you and your friend’s favourite app.
These are all open protocols that allow for direct communication but garden off others: activitypub, email, irc, matrix, xmpp, bluesky, nostr, simplex, theema, tox, jam…

Optimal Computation from Fluctuation Responses
The energy cost of computation has emerged as a central challenge at the intersection of physics and computer science. Recent advances in statistical physics -- particularly in stochastic thermodynamics -- enable precise characterizations of work, heat, and entropy production in information-processing systems driven far from equilibrium by time-dependent control protocols. A key open question is then how to design protocols that minimize thermodynamic cost while ensur- ing correct outcomes. To …

Cheat-Penalised Quantum Weak Coin-Flipping
Coin-flipping is a fundamental task in two-party cryptography where two remote mistrustful parties wish to generate a shared uniformly random bit. While quantum protocols promising near-perfect security exist for weak coin-flipping -- when the parties want opposing outcomes -- it has been shown that they must be inefficient in terms of their round complexity, and it is an open question of how space efficient they can be. In this work, we consider a variant called cheat-penalised weak coin-flipp…

Self-driving cars: Are we there yet?
Autonomous driving remains a highly active research domain that seeks to enable vehicles to perceive dynamic environments, predict the future trajectories of traffic agents such as vehicles, pedestrians, and cyclists and plan safe and efficient future motions. To advance the field, several competitive platforms and benchmarks have been established to provide standardized datasets and evaluation protocols. Among these, leaderboards by the CARLA organization and nuPlan and the Waymo Open Dataset …

Probing Non-Markovian Quantum Channels via Hilbert-Schmidt Speed and Fidelity Enhanced Teleportation Protocols
The reliable transmission of quantum information remains a central challenge in the presence of environmental noise. In particular, maintaining high teleportation fidelity in open quantum systems is hindered by decoherence, which disrupts quantum coherence and entanglement. Traditional noise mitigation techniques often neglect the rich temporal correlations present in realistic environments. This raises a key question: can non-Markovian memory effects be harnessed to improve the performance of …
