Endorsement Key (EK)

An Endorsement Key (EK) is a unique digital identifier embedded in a computer’s security chip, known as a Trusted Platform Module (TPM). Think of it as a digital fingerprint that ensures the device can securely prove its identity. This key helps establish trust when communicating with other systems, verifying that the device is genuine and hasn't been tampered with. EKs are crucial for secure transactions, digital rights management, and safeguarding sensitive information by providing a hardware-based foundation for security.
