2. MHP-PKI
Responsible for MHP application security. DVB-MHP PKI (Public Key Infrastructure, Public Key Infrastructure) provides the backbone for applications and files that authorize verification broadcast to MHP receivers. This authorization process is designed to ensure that the application code is executed on devices connected to the broadcast network without being modified by the author after development, the application can only access restricted resource sets that have been authorized to access.
DVB-MHP PKI depends on the integrity of the certificate, which is used to authenticate the identity of the entity, and the entity is marked to the file tree of the application. The certificate of the highest level, the so-called "Root Certificate", is embedded into each MHP receiver by its manufacturer and used to identify the next level of certificate in the hierarchy. Authentication is a repetitive process until you encounter a leaf certificate and authenticate it. Therefore, the user can ensure that the application is not modified and the application only uses the desired resources.
DVB-MHP PKI is established and operated by wisekey SA, representing DVB business SARL.
