Chain of Trust - Root Certificate Authority

Public Key Cryptography and Digital Certificates that can be used to encrypt or to digitally sign any information such as communication data or device firmware updates. All these processes rely on the concept of “Digital Trust” and “Root of Trust”, as the only way to ensure that data comes from authentic devices, or to safely apply a firmware update that has not been tampered. SEAL SQ allows you to use publicly or privately trusted Root Certification Authorities, and adapt the Trust Model to your business needs.
