An activeX control may be implemented using java, and imply
all the assurances of the users java virtual machine.
I would agree that its important for any user/buyer of crypto
to know and trust the source of his/her virtual machine,
as much as the operating system. In some implementations,
the viritual machine and OS are one and the same. The
assurances, due to evaluation, of the OS kernel
and reference monitor (e.g. NT) and reliance on
CPU-based privilege mode enforcement can carry over to
assure the VM to the same level as the OS, to all intents and
purposes.
This is a distinguishing factor of OS and non-OS
java clients for serious users of actual internet security
technology.
A site's firewall can scan the activeX control's java
opcodes and ensure they meet "security requirements"
beyond mere well-formedness, before the control enters
the enclosure for execution. And this is not theory...
