Abstract (en)
[origin: FR2774187A1] System comprises a reader (LCL) with a network interface creating an upper communications layer for exchange of data with the protected applications, a micro-controller (100) programmable only once which integrates two separate circuit parts on a silicon chip that are separated by an interface and a portable device (CL) able to store a large number of access authorizations. Both reader and portable device are protected both logically and physically against non-authorized access. Any user wishing to use software that is protected by the system must first possess a license card (CL) on which are recorded the user authorizations he has for the software protected with the system. The license card is read by the reader (LCL).
