Abstract
An apparatus and system provide a tamper-resistant scheme for portability of DRM-protected digital content. According to embodiments of the invention, a portable crypto unit may be utilized in conjunction with a VT integrity services (VIS) scheme as well as a Virtual Machine Manager (VMM) and a TPM to provide a secure scheme to protect digital content. Additionally, in one embodiment, the digital content may be partitioned into blocks comprising multiple segments to further enhance the security of the scheme.
