Abstract
Personal Video Recorders (PVR) are attractive to users because they enables us to watch content without facing time-restrictions. On the other hand, enterprises want to store content safely by using a proper encryption method to prevent a loss of their profits due to the leakage of content through PVR. Thus, it is necessary for enterprises to apply a method that effectively hinders the leakage of content while guaranteeing a certain level of QoS (Quality of Service). In this paper, we proposed a secure PVR method which uses a chipset-pairing, a form of advanced CAS. The proposed scheme has its merit in the fact that it can be directly usable for systems which use a chipset-pairing. Also, it generates a reasonable overhead to users and is effective to the leakage of content.
