Abstract

A transponder is embedded in the surface of the compact disk with a photo-diode structure in the surface of the chip which can interpret the modulation of the sequential scanning laser beam. The transmitter, which can be a LCD, forms a reflecting area in the middle of the receiver. Coils embedded in the CD cut the interference magnetic field of the CD drive and supply energy to the chip. Read and write paths to the chip are different.

Description

Auch Read-Write-CD's besitzen heute nicht die Möglichkeit, moderne Authentifizierungsverfahren zu unterstützen. Für solche Verfahren ist es immer notwendig, einen Secret Key nicht lesbar abzuspeichern sowie diesen Secret Key mit einem Crypt-Algorithmus und mindestens einer Zufallszahl zu einer neuen Zufallsfolge zu verarbeiten.Even read-write CDs do not have the option of modern today Support authentication procedures. It is always for such procedures necessary to store a secret key illegibly as well as this secret key a crypt algorithm and at least one random number for a new one Random sequence to process.

Nach dem heutigen Stand der Technik geht man davon aus, solche Verfahren durch Implementation eines zusätzlichen Lesegerätes entweder für Smart-Cards oder für Crypto-Transponder im CD-ROM-Laufwerk zu implementieren. Der notwendige Transponder wird dabei in die Kunststofflayer der CD einlaminiert. Mit der neuartigen Technologie von TeraTron ist dies nicht mehr notwendig. Basis ist die Möglichkeit, mit einem Crypto-Chip auf optischem Wege zu kommunizieren. Dabei wird unterschieden zwischen dem Weg vom CD-Writer zum Chip und zurück vom Chip zum CD-Writer.According to the current state of the art, it is assumed that such procedures are followed Implementation of an additional reader either for smart cards or for Implement crypto transponders in the CD-ROM drive. The necessary The transponder is laminated into the plastic layer on the CD. With the novel Technology from TeraTron is no longer necessary. Basis is the possibility communicate optically with a crypto chip. Doing so differentiated between the way from the CD writer to the chip and back from the chip to CD writer.

Die Oberfläche des Silizium-Chips besitzt eine Foto-Dioden-ähnliche Struktur, die die Modulation des sie sequentiell berührenden Laserstrahles interpretieren kann. Spiegelbildlich zum Zentrum dieses Empfangschips ist der Sendechip untergebracht, möglicherweise ausgebildet als LCD-Struktur. Die Energieversorgung des Chips erfolgt durch eine Spule, die ein wenig außerhalb des Zentrums der CD im Kunststoff untergebracht wird und durch die Rotation der CD durch das Streufeld des Antriebsmotors mit elektrischer Energie versorgt wird.The surface of the silicon chip has a photo-diode-like structure that the Modulation of the sequentially touching laser beam can interpret. The transmitter chip is mirrored to the center of this receiver chip, possibly designed as an LCD structure. The energy supply for the chip is done by a coil that is a little outside the center of the CD in the plastic is housed and by the rotation of the CD through the stray field of the Drive motor is supplied with electrical energy.
