The Quantum Threat

Why Post-Quantum Security Matters

Quantum computers are advancing rapidly. Today's encryption could be broken tomorrow. We're preparing your privacy for the future.

The Quantum Threat

Quantum computers can break RSA and elliptic curve cryptography—the backbone of today's secure communications. When large-scale quantum computers arrive, messages encrypted today could be decrypted tomorrow.

Harvest Now, Decrypt Later

Adversaries are already collecting encrypted data today, waiting for quantum computers to decrypt it. Your private messages sent now could be exposed in the future unless protected with quantum-resistant encryption.

Future-Proof Protection

Froorio implements NIST-standardised post-quantum algorithms. Your messages and calls are protected not just from today's threats, but from tomorrow's quantum-powered attacks as well.

Understanding the cutting-edge algorithms that protect your communications from both classical and quantum computing threats.

Kyber (ML-KEM)

Post-Quantum Key Encapsulation

Kyber is a lattice-based key encapsulation mechanism selected by NIST for post-quantum standardisation. It enables two parties to establish a shared secret key over an insecure channel, even in the presence of quantum adversaries.

  • Lattice-Based Security: Based on the hardness of the Module Learning With Errors (MLWE) problem, which remains secure against quantum attacks.
  • NIST Standardised: Selected as the primary post-quantum key encapsulation mechanism (ML-KEM) in the NIST post-quantum cryptography standardisation process.
  • Froorio Uses Kyber768: We implement Kyber768 for key exchange, providing approximately 192 bits of security against both classical and quantum attacks.
  • Efficient Performance: Compact key sizes and fast operations make it practical for mobile devices without compromising battery life.

Dilithium (ML-DSA)

Post-Quantum Digital Signatures

Dilithium is a lattice-based digital signature scheme, also selected by NIST. It ensures message authenticity and integrity, verifying that messages truly come from who they claim to be from.

  • Authentication Guarantee: Provides cryptographic proof that messages haven't been tampered with and genuinely originate from the sender.
  • NIST Standardised: Selected as the primary post-quantum digital signature algorithm (ML-DSA) by NIST.
  • Non-Repudiation: Ensures senders cannot deny having sent a message, crucial for secure communications.
  • Perfect Complement to Kyber: Together with Kyber, provides complete post-quantum security for both key exchange and authentication.

Post-quantum cryptography refers to cryptographic algorithms designed to be secure against attacks by both classical computers and quantum computers. Traditional encryption methods like RSA could be broken by sufficiently powerful quantum computers using algorithms like Shor's algorithm. Post-quantum algorithms, such as Kyber and Dilithium, are based on mathematical problems that remain hard even for quantum computers to solve.

While large-scale quantum computers don't exist yet, the "harvest now, decrypt later" threat is real. Adversaries, including nation-states, are collecting encrypted communications today with the intention of decrypting them once quantum computers become available. If you value long-term confidentiality of your communications, you need post-quantum encryption today.

Froorio uses a layered approach: Kyber768 for quantum-resistant key exchange, Dilithium for digital signatures and authentication, and AES-256-GCM for actual message encryption. This combination ensures your messages are protected from interception, tampering, and future quantum attacks. All encryption happens on your device—we never have access to your unencrypted messages.

Yes, absolutely. All voice and video calls in Froorio use WebRTC with the same post-quantum encryption layer. Your calls are end-to-end encrypted, meaning the audio and video data is encrypted on your device and only decrypted on the recipient's device. We operate TURN servers solely for connectivity—we cannot access call content.

Froorio is designed with privacy by default. We collect the absolute minimum data necessary to operate the service: your phone number for account verification, and some metadata required for message routing. We cannot read your messages, see your files, or listen to your calls. For complete details, please review our Privacy Policy.

We believe in transparency. Our cryptographic implementations are based on well-audited, open-source libraries. We're committed to security through openness rather than obscurity. Details about our cryptographic protocols and security architecture are available for review.
