CASTOR
Continuum of Trust: Increased Path Agility and Trustworthy Device and Service Provisioning
Improving digital communications safety and trustworthiness
As cloud-centric services struggle to meet emerging user needs, computing has shifted closer to the edge or far-edge, forming a 'compute continuum'. This continuum faces challenges in securely supporting end-to-end information sharing due to untrusted hardware and software infrastructures with changing trust states. The EU-funded CASTOR project aims to enable trustworthy communications across this continuum by capturing (security, privacy, trust) service requirements as CASTOR policies enforced in the traffic engineering process. CASTOR focuses on distributed attestation, optimal path computation based on trust properties, and vendor-agnostic trusted path establishment across domains. Its technologies will be tested in four use cases involving security-critical information providing insights to enhance trust-related standards and demonstrate CASTOR’s effectiveness in diverse environments.
