Actions

TF-M has been under active development since it was launched in Q1'18. It is being designed to include

1. Secure boot ensuring integrity of runtime images and responsible for firmware upgrade.
2. Runtime firmware consisting of TF-M Core responsible for secure isolation, execution and communication aspects. and a set of Secure Services providing services to the Non-Secure and Secure Applications. The secures services currently planned to be supported are Secure Storage, Cryptography, Audit Logs, Attestation, Provisioning and Platform Services
   
   Roadmap below shows when the services are getting supported and then enhanced.
