Abstract.
This chapter describes two protocols for the secure download of content
protection software to mobile devices. The protocols apply concepts from
trusted computing to demonstrate to the source of the software that a
platform is in a suffciently trustworthy state before any application or
associated keys are securely downloaded. The protocols are described at an
abstract level before being mapped on to specific trusted platform
architectures. The protocols are designed to allow mobile devices to receive
broadcast content protected by proprietary conditional access applications.
They may also be applied in the general case where demonstration of a secure
execution environment is required before an application is downloaded.
