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.
