Advanced Key Management with Client-Side Keyring

Overview

[Placeholder: Specific content for "Advanced Key Management with Client-Side Keyring" to be updated once provided from security.html.]

The Advanced Key Management with Client-Side Keyring feature empowers UnoLock CybVault users to securely generate, store, and manage encryption keys entirely on their local device, reinforcing the zero-knowledge security model. By maintaining a client-side keyring, UnoLock ensures that cryptographic keys, used for encrypting sensitive data like cryptocurrency wallets, documents, or personal records, never leave the user’s device or are exposed to servers. This feature provides robust key management capabilities, including key generation, rotation, and backup, while protecting against unauthorized access and ensuring user control over their digital assets.

How It Works

  • Key Generation: The client-side keyring generates cryptographic keys (e.g., AES-256 keys) locally on the user’s device, using secure random number generation to ensure key strength.
  • Local Storage: Keys are stored in a secure client-side keyring, protected by device-level security (e.g., secure enclave or encrypted storage), ensuring they never leave the device.
  • Key Rotation: Users can periodically rotate keys to enhance security, with UnoLock facilitating seamless re-encryption of data using new keys without exposing them to servers.
  • Backup and Recovery: The keyring supports secure key backup options, such as encrypted exports or integration with hardware tokens, allowing users to recover keys without compromising security.

Security Implications

  • Zero-Knowledge Privacy: By keeping keys client-side, UnoLock ensures that servers, third parties, or attackers cannot access or misuse encryption keys, maintaining user privacy.
  • Protection Against Server Breaches: Since keys are never stored on UnoLock’s servers, a server compromise cannot expose user keys or decrypt data.
  • User Control: The client-side keyring gives users full control over their keys, enabling secure management without reliance on external systems.

Use Cases

  • Cryptocurrency Wallet Security: Users can manage encryption keys for cryptocurrency wallets within the client-side keyring, ensuring secure storage and access.
  • Sensitive Data Protection: Individuals or businesses handling confidential data, such as legal or financial records, can use the keyring to securely manage encryption keys.
  • Multi-Device Key Management: Users accessing their vault from multiple devices can synchronize encrypted keyring backups, maintaining consistent security across platforms.

Why It Matters

Effective key management is critical to maintaining the security of encrypted data. The client-side keyring ensures that users retain full control over their cryptographic keys, protecting against server-side vulnerabilities and reinforcing UnoLock’s commitment to zero-knowledge privacy. This feature provides a robust, user-centric solution for safeguarding digital assets in an increasingly threat-prone environment.

FAQs

What is a client-side keyring?

A client-side keyring is a secure, local repository on the user’s device that stores and manages cryptographic keys, ensuring they never leave the device or are exposed to servers.

Can UnoLock access my encryption keys?

No, UnoLock operates a zero-knowledge model, meaning that all keys are generated and stored locally in the client-side keyring, inaccessible to UnoLock’s servers.

What happens if I lose access to my device?

The keyring supports secure backup options, such as encrypted exports or hardware token integration, allowing key recovery without compromising security.

Compliance & Privacy Regulations

  • GDPR & HIPAA Compliance: The client-side keyring ensures that encryption keys remain private and secure, supporting compliance with GDPR, HIPAA, and other data protection regulations by preventing unauthorized access.

Integration with Other Features

  • Client-Side Encryption Using AES-256 GCM: The keyring manages the keys used for client-side encryption, ensuring secure encryption and decryption of data locally.
  • FIDO2 Authentication with WebAuthn: Integrates with FIDO2 authentication to protect access to the keyring, ensuring only authorized users can manage or use the keys.
