Trusted computing

(also TC)

Trusted computing definition

Trusted computing is a computing structure created to boost the security of computers or networks by forming a foundation of trust. Trusted computing guarantees that hardware, software, and firmware elements function as designed, delivering a safer environment for users by thwarting unauthorized access, manipulation, and security incidents.

Trusted computing examples

  • Trusted Platform Module (TPM): A dedicated microcontroller that securely stores encryption keys, passwords, and digital certificates. TPMs can be found in many modern computers, ensuring data protection and platform integrity.
  • Hardware Security Module (HSM): A physical device that safeguards and manages digital keys, performs encryption and decryption, and provides strong authentication for critical applications and services.
  • Intel Software Guard Extensions (SGX): A set of security-related instruction codes that enable applications to create a protected area of memory called an enclave, which is inaccessible to other processes running on the same system.

Trusted computing vs. secure computing

Trusted computing focuses on providing a root of trust and ensuring the integrity of hardware, software, and firmware components. Secure computing encompasses a broader range of security measures, including encryption, access control, and vulnerability management, aimed at protecting sensitive data and ensuring confidentiality, integrity, and availability.

Pros and cons of trusted computing

Pro:

  • Enhanced security, prevention of unauthorized access and tampering, protection of sensitive data.

Con:

  • Potential privacy issues, increased complexity, and possible vendor lock-in.

Trusted computing tips

  • Use hardware components with built-in trusted computing features.
  • Keep your software and firmware up-to-date.
  • Implement strong access controls and authentication mechanisms.
  • Consider using a VPN like NordVPN to encrypt your internet connection and protect your data from eavesdropping.
