Certificate Management Overview

Device authentication and security in Peridio relies on X.509 certificates for device identity and communication security.

Core Concepts​

Peridio uses a comprehensive certificate management system that provides:

  • Device Authentication - Cryptographic proof of device identity
  • Secure Communication - TLS/SSL encrypted connections
  • Firmware Validation - Code signing and verification
  • Trust Chain Management - Hierarchical certificate authorities

Certificate Components​

The Peridio certificate infrastructure consists of:

  • Certificate Authorities (CAs) - Root and intermediate trust anchors
  • Device Certificates - Individual device identity credentials
  • Signing Keys - Code signing certificates for firmware
  • Verification Certificates - Platform validation certificates

Getting Started​

  1. Plan Your PKI - Design your certificate hierarchy
  2. Create CAs - Establish root and intermediate authorities
  3. Generate Device Certificates - Issue device credentials
  4. Configure Signing - Set up firmware signing keys
  5. Deploy to Devices - Install certificates securely

Management Options​

Self-Managed​

Full control over your PKI infrastructure:

  • Generate and manage your own CAs
  • Issue device certificates manually
  • Handle rotation and revocation

Platform-Managed​

Let Peridio handle the complexity:

  • Automated certificate generation
  • Built-in rotation policies
  • Integrated revocation management

Security Considerations​

  • Store private keys securely
  • Use hardware security modules when possible
  • Implement regular rotation schedules
  • Monitor certificate expiration
  • Plan for emergency revocation
