Zero-Knowledge: Proton Drive practices zero-knowledge encryption, where Proton does not have access to the encryption keys or the content of your files, providing you with absolute privacy.
Implementation of Zero-Knowledge End-to-End Encryption by Proton Drive:
- File Encryption:
- Elliptic Curve Cryptography (ECC Curve25519): Proton Drive employs the latest high-performance elliptic curve encryption to protect your files. This advanced encryption is secure against all known attacks while requiring less computational power.
- OpenPGP Standard: Using the open-source and battle-tested OpenPGP standard, each Proton user has a public key for encryption and a private key for decryption. Since only you have access to your private key, only you can view your data.
- Large File Encryption:
- Proton Drive's unique technology splits large files into 4MB chunks for client-side, high-performance end-to-end encryption. Each chunk is signed with a hash to prevent tampering or reordering, ensuring data integrity upon access or download.
- Digital Signatures:
- To maintain the integrity of your data, Proton Drive uses cryptographic signatures. This allows you to detect any attempt at tampering with your files or folders immediately.
- Censorship Circumvention:
- Alternative Routing: Proton Drive's alternative routing feature helps bypass government or ISP censorship, automatically detecting when your connection is censored and rerouting traffic to ensure access.
- Tor Onion Site: For enhanced anonymity and to overcome advanced censorship, you can access Proton Drive via the Tor network. This is achieved using the Tor Browser or Proton's VPN over Tor feature for better protection against surveillance.
- Open Source and Security Audits:
- As an organization founded by scientists, Proton believes in transparency and peer review. All applications and encryption libraries are open source, enabling independent verification by researchers and security experts.
