What are the benefits of a delegated Certificate Authority (CA)?
The MTMO allows for the delegation of key management to adopters. The benefit of a delegated CA is that adopters can control the cost structure of key management either by establishing a CA in-house, outsourcing it to a service provider, or leveraging existing systems. This also allows adopters to design their own delegated trust hierarchy to meet individual business needs. For example, a large device manufacturer can design its trust hierarchy to have each geographical division be in charge of its own delegated CA; each geographical division can then delegate the CA responsibility to different sub-product divisions if the adopter chooses to. Alternatively, the device manufacturer can choose to have just one CA for all its devices and order all the device keys from a Listed Trust Service Provider.
