Inside VaultCore's Secure Architecture

Military-grade technology meets open-source transparency for ultimate crypto protection.

Hardware Module Architecture

Every component engineered for maximum security and reliability.

Secure Element Chip

The heart of VaultCore's security. Our certified secure element (Common Criteria EAL6+) provides hardware-level encryption and tamper detection.

  • • AES-256 hardware encryption
  • • Physical tamper resistance
  • • True random number generator
  • • Side-channel attack protection

Secure Display Module

High-contrast OLED screen directly connected to the secure element ensures transaction details cannot be manipulated by compromised computers.

  • • Anti-tampering verification
  • • QR code transaction display
  • • Address verification interface
  • • Multi-signature confirmation

Physical Confirmation Buttons

Hardware buttons provide tactile confirmation of transactions. No software can simulate button presses, preventing remote exploitation.

  • • Dual-confirmation system
  • • Press sequence protection
  • • Timeout mechanisms
  • • Accidental press prevention

Encryption Protocols & Security Certification

Industry-leading cryptographic standards validated by independent security audits.

Cryptographic Algorithms

VaultCore implements industry-standard cryptographic primitives:

  • AES-256-GCM: Authenticated encryption for data at rest
  • ECDSA: Elliptic curve digital signatures (secp256k1)
  • SHA-256: Secure hashing for transaction verification
  • PBKDF2: Key derivation with 100,000+ iterations
  • BIP32/BIP39/BIP44: HD wallet standard compliance

Key Management

Private keys never leave the secure element:

  • Hardware-generated entropy: True random number generation
  • Seed phrase backup: 24-word BIP39 mnemonic
  • Optional passphrase: 25th word for hidden wallets
  • Multi-signature support: 2-of-3 and 3-of-5 schemes
  • Derivation paths: Unlimited address generation

Common Criteria EAL6+

Secure element certified to the highest commercial security standard. Independently verified by accredited laboratories for resistance against sophisticated attacks.

CE & RoHS Compliance

Full European Union regulatory compliance. Meets all safety, health, and environmental protection standards for consumer electronics in the DACH region.

ISO 27001 Certified

Our development and manufacturing processes follow information security management best practices. Regular audits ensure continued compliance.

Independent Security Audits

VaultCore undergoes continuous security review by leading cybersecurity firms and the open-source community.

Auditor: Trail of Bits

Scope: Complete firmware codebase, bootloader, and secure element integration

Findings: Zero critical vulnerabilities. Two low-priority recommendations implemented in version 2.1.0

Report: Publicly available on GitHub

Auditor: Kudelski Security

Scope: Physical security, side-channel analysis, fault injection testing

Findings: Hardware design validated. Successfully resisted advanced physical attacks including power analysis and electromagnetic probing.

Report: Available upon request

Auditor: NCC Group

Scope: Cryptographic library implementation, key generation, and signature schemes

Findings: All cryptographic implementations follow best practices. No timing vulnerabilities detected.

Report: Publicly available on GitHub

Open-Source Transparency

Complete visibility into every aspect of VaultCore's security implementation.

Open Source Development

Why Open Source Matters

Proprietary security is security through obscurity — a fundamentally flawed approach. VaultCore embraces transparency:

Public Repositories

All firmware, desktop software, and mobile applications available on GitHub. Fork, audit, and contribute to VaultCore's security.

Community Auditing

Security researchers worldwide continuously review our code. Responsible disclosure program rewards vulnerability reports.

Reproducible Builds

Verify that the firmware on your device matches the published source code. No hidden backdoors possible.
