Security Contexts

C-Trust enables you as developer to use Preconfigured Security Contexts, ensuring that you remain in control of system operation today, and into the future. With Embedded Trust, companies are able to define custom Security Contexts, which uniquely service their specific needs.

Security Contexts define the configuration of the trusted execution environments. Security Contexts enable organizations to simplify:

  • Complex cryptographic device identities and ownership structures
  • Creation of a robust Root of Trust, ensuring device authentication, authorization and attestation, the core proofs of identity
  • Implementation of security hygiene, dependant on device hardware support
  • Secure Boot Manager extensions to support core boot functionality
  • Application of patches, updates, and other lifecycle management criteria
  • Delegation of identity for onboarding into cloud infrastructure applications

These Security Contexts provide the foundation for a set of core security concepts, enabling Security From Inception, including protection of Intellectual Property, which is about inhibiting IP theft and malware injection, and Production Control, which is about protecting keys across development and production.

Security Contexts

The IP Protection and Production Control Security Contexts have been designed to enable developers to rapidly protect the high value and critical IP that organizations create, and to provide reassurance that only authorized and authenticated IP can be installed on devices.
