Abstract
A system for securely storing CD-ROM data including a CD-ROM having data encrypted at least in part with a cryptographic algorithm having a decryption key K, a CD-ROM drive for receiving the CD-ROM, an electronic decryption microcircuit embedded in the CD-ROM, means for exchanging information between the CD-ROM drive and the electronic decryption microcircuit embedded in the CD-ROM, and a chip card containing at least a part K1 of the decryption key K, any remaining part K2 of the decryption key K being in the electronic decryption microcircuit embedded in the CD-ROM. Also included is a secure means for securely exchanging information between the chip card and the electronic microcircuit embedded in the CD-ROM. Further, the electronic decryption microcircuit embedded in the CD-ROM includes an antenna which provides, without the presence of contact, both an electrical power supply to the decryption microcircuit from an external source and exchanges of information with the external source.
