PURPOSE: A method and a system of encrypted data delivery are provided to perform multipoint delivery of encrypted digital data to specific destinations. CONSTITUTION: A digital data is delivered over a high-speed multipoint delivery network(3) suitable for delivering large quantities of data at high speed in a broadband environment. A content producer(1) sends digital data content to an electronic delivery operator(2) from which the content is delivered to specific destinations(A,B), over the high-speed multipoint delivery network(3). The high-speed multipoint delivery network(3) is a broadband network which includes a broadcasting satellite, optic fibers and/or other resources. Such a network is capable of transmitting large quantities of data at least in the downward direction. Alternatively, the network has bidirectional capabilities permitting mass data transmission in both the upward and the downward directions.
