Signal Raises the Bar: Post-Quantum Cryptography Enhances Messaging Security in 2025
In October 2025, Signal deployed a groundbreaking update to its secure messaging protocol, introducing a post-quantum cryptographic architecture known as the Sparse Post Quantum Ratchet (SPQR). Developed in collaboration with PQShield, AIST, and NYU, this implementation combines classical elliptic-curve cryptography with a new quantum-resistant Key Encapsulation Mechanism (KEM). The protocol uses both the classical Double Ratchet and the new KEM-based ratchet in parallel, mixing their outputs to derive message encryption keys. This hybrid approach ensures that even if one cryptographic system is compromised—by quantum or conventional means—messages remain protected by the other system, significantly enhancing Signal’s defense against future quantum-enabled attacks. Signal’s quantum-safe upgrade sets a precedent as quantum and post-quantum threats become increasingly realistic, with other messaging and critical infrastructure providers closely monitoring and evaluating similar migration paths. The move signals a wider trend toward proactive cryptographic agility and future-proofing, in line with regulatory and industry pressures to stay ahead of emerging attack vectors.
