SIMULTANEOUS PROTECTION FOR SEVERAL TYPES OF SOFTWARE OF SEVERAL SOFTWARE DESIGNERS

摘要

The invention concerns the protection of several types of software against unauthorised use, consisting in an apparatus (licence card reader LCR) for simultaneously protecting several types of software of several software designers and comprising at least one communication peripheral (network, I/S port), a microcontroller programmable only once which integrates on the same silicon chip two parts separated by an interface. The integrated circuit is logically and physically protected against all attempts of unauthorised intrusion. The invention also concerns a portable apparatus of relatively small size with respect to the chip card connected for its use with the LCR apparatus, comprising at least a detachable recording module with high storage capacity, a microcontroller made secure against all attempts at unauthorised intrusion into its internal circuits. Thus the invention provides protection for several types of software independently of their editors with a single apparatus.
