Digital Rights Management (DRM) is a system to
protect high-value digital assets and control the distribution and
usage of those digital assets. Digital licensing controls the
contents to be accessed by the consumers. One of the major issues
raised by DRM systems concerns the integrity of this license. In
this paper, we propose a threshold based group-oriented
nominative proxy signature scheme (TB-GO-NPSS) which
supports an original provider to delegate his/her signing ability to
the partial members of the proxy group having n members and to
designate the partial members of the verifier group having l
members to verify his/her digital licenses for the mobile users.
The proposed scheme can guarantee that the digital products
come from the authorized providers. A formal security analysis
demonstrates that our scheme is secure enough to be used in
DRM systems.
