Our Core Technologies & Standards

View all Technologies

Block Integrated Trust (BIT)

Brings trusted computing principles to block-level storage, enabling integrity, attestation, and protection of data blocks at the device layer.

Cyber Resilient Technologies (CyRes)

TCG's cyber-resilience technology for protecting persistent code, detecting unexpected states, and recovering platforms to a known trusted state.

Device Identifier Composition Engine (DICE)

Device Identifier Composition Engine establishes a unique cryptographic identity for resource-constrained devices and IoT systems with minimal hardware.

Platform Certificates

TCG's provenance artifacts asserting Roots of Trust, Trusted Building Blocks, and component composition for supply-chain assurance and attestation appraisal.

Reference Integrity Manifest (RIM)

Signed, machine-readable reference measurements used to verify a device boots and runs in its expected, trusted state.

Storage Security

TCG's architecture for interoperable security on trusted storage devices: self-encrypting drives, access control, locking, and Opal, Ruby, and Opalite classes.

TPM Software Stack (TSS)

A consistent software interface that lets applications and operating systems interact with TPM hardware across vendors, architectures, and platforms.

Trusted Platform Module (TPM)

Hardware-based root of trust that securely generates and stores cryptographic keys, attesting to the integrity of the platform it runs on.

The PC Client Platform Specific Profile for TPM 2.0 systems defines the requirements for platform firmware to initialize and interact with a TPM 2.0 device in a PC Client platform. This specification should be used in conjunction with the TCG UEFI Protocol Specification Family 2.0, the TCG Physical Presence Interface Specification, and the TCG ACPI Specification to design and implement a PC Client TPM 2.0-enabled platform. This specification replaces the requirements defined in the PC Client Implementation Specification for Conventional BIOS and the PC Client UEFI Platform Specification for systems with TPM 2.0 devices.
