Internxt Drive's post-quantum cryptography was made possible by advances in post-quantum cryptography developed in part by the National Institute of Standards and Technology (NIST).
NIST worked with leading cryptographers to create encryption protocols that resist future quantum computing threats.
Internxt uses Kyber 512 encryption, which NIST awarded the best PQE because of its comparatively small encryption keys that two parties can exchange easily, as well as its speed of operation.
Internxt uses this encryption, alongside our current zero-knowledge policies to ensure the security of your files and your privacy against current and future cyber threats.
What is Kyber 512 encryption?
Kyber 512 is a key encapsulation mechanism (KEM) based on the hardness of solving the learning-with-errors (LWE) problem over module lattices.
This lattice-based cryptography is effective because quantum computers cannot solve these types of problems efficiently, making it a secure choice for future-proofing encryption.
Is post-quantum cryptography the most secure encryption?
Most cloud providers use AES-256 encryption, which encrypts data using a 256-bit key. This key transforms your files into unreadable ciphertext that can only be decrypted by authorized users with the correct key.
While AES-256 is secure against current computers, quantum computers could eventually break this encryption. Quantum computers have the power to solve problems that would take traditional computers hundreds of years to crack, making them a potential threat to current encryption methods.
While classical computers use bits to store information as either a zero or a one, quantum computers use qubits, representing both a zero and a one simultaneously. This ability, known as superposition, allows quantum computers to solve complex problems much faster than classical computers.
As a result, the power of quantum computers could potentially break encryption methods like RSA, which are currently used for secure data transmission.
Internxt's post-quantum encryption addresses this concern by relying on mathematical problems that quantum computers cannot solve efficiently.
You don’t need a quantum computer to use this encryption, as the standards developed by NIST are designed to run directly on your device.
