1. Method for transmitting information (20) with access control via a network (3) utilizing an IP type protocol. According to the invention, at transmission: scrambling a first datagram (23); defining a header (24) comprising at least one datum identifying the access control means; concatenating this header (24) with the first scrambled datagram (23) in order to create a data block (26); encapsulating the data block (26) in a second IP datagram (30); transmitting this second IP datagram (30) over the network; at reception: extracting the data block (26) from the datagram received; extracting the header (24); descrambling the first datagram (23) if access to this data is authorized; delivering the descrambled data.
