Attestation

A process of verifying and validating the identity and attributes of non-human entities.

Description

Attestation in the context of Non-Human Identities (NHIs) refers to the methods and processes used to confirm the identities of entities that are not human, such as devices, applications, or automated systems. This verification may involve the use of cryptographic techniques to ensure that the identity of the NHI is legitimate and that it possesses certain attributes that can be trusted. Attestation is crucial in environments where NHIs interact with human users or other systems, as it helps to establish a level of trust and ensures the integrity of transactions. Various attestation protocols exist, including remote attestation, where the state of a system can be verified remotely. This process is essential for security in Internet of Things (IoT) applications, blockchain systems, and other automated environments where trust is a critical factor. By ensuring that NHIs can be reliably identified and their claims verified, organizations can mitigate risks associated with unauthorized access and ensure compliance with security policies.

Examples

  • A smart thermostat that verifies its identity to a home automation system before allowing it to communicate.
  • A cloud service that uses attestation to confirm the identity of a virtual machine before granting it access to resources.

Additional Information

  • Attestation can be performed using various standards, such as TPM (Trusted Platform Module) or DAA (Direct Anonymous Attestation).
  • The process of attestation often includes checking for compliance with policies and regulations related to security and data protection.
