• Attestation: TPM 2.0 can attest to the integrity of the system’s hardware and software configuration, ensuring that the system has not been tampered with.
• Measured Boot: TPM 2.0 can measure and record the boot process, allowing for the verification of system integrity.

TPM 2.0 and Anti-Cheat: Why It Matters

The inclusion of TPM 2.0 is a cornerstone in ensuring that the PC environment is a legitimate one, and that no malicious third-party software is running during game-play. By leveraging the TPM 2.0 capabilities, anti-cheat systems gain a robust mechanism for:

• Secure Boot Validation: Verify the integrity of the boot process and the operating system, preventing the loading of malicious drivers or modified system files.
• Hardware Identity Verification: Securely identify and verify the hardware configuration of the PC, making it more difficult for cheaters to spoof or change their hardware profiles.
• Secure Key Management: Protect cryptographic keys used by the anti-cheat software, preventing cheaters from manipulating or disabling the system.
• Rootkit Protection: Guard against rootkits that attempt to hide their existence from anti-cheat software.

Secure Boot: Guaranteeing a Verified Boot Process

Secure Boot is a security feature of the Unified Extensible Firmware Interface (UEFI) that ensures only trusted software is loaded during the boot process. Secure Boot uses cryptographic signatures to verify the authenticity of the operating system, boot loaders, and drivers before they are allowed to run.

How Secure Boot Works

1. Key Storage: Secure Boot relies on cryptographic keys stored in the system’s firmware (UEFI).
2. Signature Verification: Before booting, Secure Boot verifies the digital signatures of the boot loader, operating system, and drivers against the trusted keys.
3. Boot Process Control: Only software with valid digital signatures is allowed to load. Any unauthorized software is blocked, preventing the loading of malicious or modified code.

Secure Boot and Anti-Cheat: A Synergistic Partnership

Secure Boot works in tandem with TPM 2.0 to provide a comprehensive security solution, enhancing the effectiveness of anti-cheat systems. Secure Boot ensures that the boot process is tamper-proof. This means that cheaters cannot modify the operating system or load malicious drivers to bypass anti-cheat measures. By requiring Secure Boot, game developers can have greater confidence in the integrity of the system.
