What is Quantum Encryption?
An overview of quantum-safe encryption technologies and how Bervice uses them to secure your files and passwords against both current and future cyber threats.
Quantum encryption refers to cryptographic methods designed to withstand the power of quantum computers. Unlike traditional algorithms such as RSA or ECC—which could be broken by future quantum attacks—post-quantum cryptography (PQC) and quantum key distribution (QKD) aim to ensure long-term confidentiality of your data.
In the context of Bervice, we focus on post-quantum cryptography, using algorithms that resist both classical and quantum attacks. This means that even if a large-scale quantum computer were built tomorrow, the encryption protecting your stored files and passwords would remain secure.
Our PQC implementation uses the - key encapsulation mechanism (selected by NIST as a quantum-safe standard) for exchanging symmetric keys, combined with - for high-speed encryption of data at rest. Passwords, metadata, and file titles are encrypted individually, so a compromise of one piece of data does not endanger the rest.
Quantum encryption also addresses the problem of harvest-now-decrypt-later attacks, where adversaries collect encrypted data today with the intention of decrypting it in the future when quantum computers are powerful enough. By encrypting with PQC now, we close that window of vulnerability.
While QKD—using quantum particles to share keys—remains experimental and requires specialized hardware, our architecture is designed to integrate with it in the future. This positions Bervice to adopt hybrid encryption models that combine PQC software-based methods with QKD’s physical-layer security.
