Abstract

Data integrity and source origin authentication are essential topics for real-time multimedia systems. But the traditional methods are not very applicable to overcome the distortion introduced in multimedia data transportation. In this thesis some security mechanics are proposed, which rely on authentication rather than on encryption methods. The highly asymmetric architectures found in ubiquitous computing applications are exploited to provide a protection of the transmitted multimedia data by means of well-known digital watermarking techniques. The advocated approach adopts public key encryption to efficiently generate non-repudiate multimedia data, whereas both the digital watermark generation and the authentication algorithms are public.

Fragestellungen der Datenintegrität und Datenquelle-Authentisierung r¨¹cken in den Mittelpunkt des Interesses f¨¹r die Echtzeit-Multimedia-Systeme. Aber die traditionellen Methoden sind nicht sehr anwendbar, die Verzerrung zu ¨¹berwinden, die im Multimediadatentransport eingef¨¹hrt wird. In die Arbeit wird ein neues Verfahren zur Sicherung von Multimediadaten vorgestellt, das auf Authentifizierung anstatt auf Verschl¨¹sselung der Rohdaten beruht. Zur Erzeugung sicherer digitaler Wasserzeichen, die in den Datenstom eingef¨¹gt werden, kommen jedoch Public Key Verschl¨¹sselungsverfahren zum Einsatz. Die besonderen Anforderungen der Verarbeitung und ¨¹bertragung in Echtzeit werden von der vorgestellten Authentifizierungs-methode geeignet ber¨¹cksichtigt.German
