* A Trust Domain is the field in which certificates may be validated.

* A client program, or a simple server, would typically have one
|
|
* trust domain. A server supporting multiple "virtual servers" might
|
|
* have a separate trust domain for each virtual server. The separate
|
|
* trust domains might share some modules (e.g., a hardware crypto
|
|
* accelerator) but not others (e.g., the tokens storing the different

|
* servers' private keys, or the databases with each server's trusted

|
|
* operation may be the creation of a signed message, the use of an

* specific trust domain, and it may have associated with it a
