  • In this article we present a system for sharing a Conditional Access Module among different visualization devices. Current pay-TV systems require having conditional access modules and smart cards replicated at every visualization device willing to access Pay-TV contents. In this article, we show how a home gateway, capable of securely distribute decryption keys to home visualization device, an inexpensive descrambler, and a home network, enable a flexible solution to access Pay-TV.
