Security Notice

The Stayforge Card utilizes industry-standard technologies to provide a balance of security and convenience. Understanding the security framework is essential for maintaining a robust system.

Authentication Overview

• Technology: The card is based on MIFARE Classic 1K technology.
• Security Mechanism: It uses the CRYPTO1 encryption algorithm and sector-based access control with Key A and Key B.
• Identification: Each card is identified by a 4-byte Unique Identifier (UID).

System-Level Security

The security of an access control system does not rely solely on the card itself but on the entire ecosystem:

• Backend Validation: The Stayforge system validates card UIDs and associated permissions in real-time or via synchronized local databases.
• Encrypted Communication: Communication between readers and the Stayforge server is encrypted to prevent data interception.
• Access Policies: Administrators must implement strict access policies and regularly review permissions.

Important Considerations

• No Guarantee of Absolute Security: While MIFARE Classic is widely used, it has known vulnerabilities to sophisticated attacks. Users requiring high-security environments should consider this when designing their security architecture.
• Complementary Measures: For high-risk areas, consider implementing multi-factor authentication (e.g., card + PIN or card + biometrics).

Stayforge provides the tools for secure operation, but the ultimate responsibility for system security lies with the administrator and the organization.
