Quantum-Safe Encryption

Every notification sent through Smooven is protected by quantum-safe encryption. This is not a premium feature or an optional add-on. It is built into every tier, for every customer.

Most internet encryption today relies on RSA and Elliptic Curve cryptography. These algorithms are secure against classical computers but vulnerable to quantum computers running Shor’s algorithm.

The threat is not hypothetical. Adversaries are already practising “harvest now, decrypt later”: recording encrypted traffic today with the intention of decrypting it once quantum computers are powerful enough. For any data that needs to remain confidential for years (medical records, financial transactions, identity data), this is a real risk today.

Smooven uses a hybrid key exchange that combines:

  1. Classical ECDH (Elliptic Curve Diffie-Hellman) for proven, battle-tested security against today’s threats
  2. CRYSTALS-Kyber (ML-KEM) for resistance against quantum attacks

Both key exchanges run in parallel. The resulting session key is derived from both, meaning an attacker would need to break both classical and quantum-resistant algorithms simultaneously.

Smooven implements the post-quantum cryptographic standards finalised by NIST in August 2024:

AlgorithmStandardPurpose
ML-KEM (CRYSTALS-Kyber)FIPS 203Key encapsulation (secure key exchange)
ML-DSA (CRYSTALS-Dilithium)FIPS 204Digital signatures for API authentication
SLH-DSA (SPHINCS+)FIPS 205Hash-based signature alternative

API keys and session tokens are derived using quantum-resistant key derivation functions. This ensures that the Dual-Key paradigm (App ID + Secret Key) maintains its security properties even in a post-quantum world.

  • No code changes required. Quantum safety is handled at the transport layer. Your API calls work exactly the same way.
  • No performance penalty. The hybrid key exchange adds negligible latency (under 1ms) to connection establishment.
  • No extra cost. Quantum safety is included in every plan, from Developer (free) through Enterprise.

Governments and regulators worldwide are mandating quantum-safe cryptography:

RegionMandate
United StatesFederal systems must adopt PQC by 2035 (NSM-10)
European UnionENISA recommending hybrid approaches starting 2025
United KingdomNCSC advising preparation for PQC migration
AustraliaASD updating ISM guidance for quantum readiness

By using Smooven, your notification infrastructure already meets these emerging requirements.
