What type of technology is used to ensure user identities and encryption keys are stored securely?

Trusted Platform Modules (TPMs) are cryptographic hardware components designed to securely store sensitive data such as user identities and encryption keys. They are implemented directly onto a device's motherboard and provide a secure environment for performing cryptographic operations.

One of the main functions of a TPM is its ability to generate, store, and manage cryptographic keys in a manner that resists tampering and unauthorized access. By providing a secure element that is resistant to physical and logical attacks, TPMs help ensure that crucial cryptographic material remains protected, thus enhancing the overall security of systems and their data.

In contrast, cloud storage solutions may provide data encryption, but they often store encryption keys in a way that can be vulnerable to attacks. Biometric security systems focus on identity verification rather than key management, while antivirus software is aimed at detecting and removing malware without specific measures for the secure storage of cryptographic information. Therefore, the unique capabilities of TPMs make them the preferred choice for securely managing user identities and encryption keys.
