The vulnerability of the rweather library and the crypto-based solutions for organizing tactical radio communications in hard-to-access areas like Meshtastic allows attackers to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the rweather library and the crypto-based solutions for organizing tactical radio communications in hard-to-access areas like Meshtastic is related to insufficient entropy during key generation. Exploiting this vulnerability allows a remote attacker to compromise the...

CVE-2025-52464

Meshtastic is an open source mesh networking solution. In versions from 2.5.0 to before 2.6.11, the flashing procedure of several hardware vendors was resulting in duplicated public/private keys. Additionally, the Meshtastic was failing to properly initialize the internal randomness pool on some...

Quantum Enhanced Entropy Pool for Cryptographic Applications and Proofs

This paper investigates the integration of quantum randomness into Verifiable Random Functions VRFs using the Ed25519 elliptic curve to strengthen cryptographic security. By replacing traditional pseudorandom number generators with quantum entropy sources, we assess the impact on key security and...

CVE-2025-52464

Meshtastic versions 2.5.0–2.6.10 expose a vulnerability where flashing procedures can duplicate public/private keys and the RNG may have low entropy, allowing an attacker to decrypt Direct Messages after collecting compromised keys. This is caused by key generation timing and insufficient randomn...

Spanning-Tree-Packing Protocol for Conference Key Propagation in Quantum Networks

We consider a network of users connected by pairwise quantum key distribution QKD links. Using these pairwise secret keys and public classical communication, the users want to generate a common conference secret key at the maximal rate. We propose an algorithm based on spanning tree packing a kno...
