Summary
- IBM is collaborating with Signal and Threema to create messaging systems that are resistant to quantum attacks.
- Ethan Heilman, a cryptographer, believes that encrypted messaging is at a higher immediate quantum risk compared to Bitcoin.
- The rise of quantum computing is prompting developers to focus on post-quantum cryptography.
Quantum computing has been identified as a potential threat to Bitcoin. However, researchers now suggest it could also jeopardize the encrypted messaging systems used by millions globally.
In a recent report, IBM discussed its initiative with Signal and Threema to revamp messaging protocols in anticipation of a future where quantum computers might breach current encryption methods.
Researchers emphasized, “Even the most advanced classical supercomputers cannot break this encryption in a feasible time frame. However, developments in quantum computing may soon change that.”
While there’s been extensive discourse about quantum threats to cryptocurrencies, Ethan Heilman argues that encrypted messaging services might be more vulnerable in the near term. His concern centers on ‘store-and-forward’ attacks, where intercepted communications could be decrypted later using quantum technology.
Signal and Threema offer end-to-end encrypted messaging and calls, storing encryption keys on users’ devices. Current encryption remains secure against classical systems, but quantum advancements pose a different threat.
Signal has started implementing the PQXDH upgrade to bolster defenses against potential quantum attacks. In 2025, they will further enhance security with the Sparse Post-Quantum Ratchet (SPQR) protocol, while Threema is exploring integrating the ML-KEM algorithm to transition to quantum-safe encryption.
