A novel multi-carrier visual cryptography scheme based on XOR and OR operations

Journal of King Saud University: Computer and Information Sciences
The conventional Visual Cryptography Scheme (VCS) relying solely on OR operations suffers from poor recovery quality and severe pixel expansion when implemented on physical transparencies.

Time in cryptography

, 2020
Time travel has always been a fascinating topic in literature and physics. In cryptography, one may wonder how to keep data confidential for some time. In this dissertation, we will study how to make private information travel to the future. This dissertation consists of three parts: Timed-release encryption, witness encryption and self-encryption ...

Backdoors in cryptography [PDF]

Diese Arbeit besteht aus zwei Teilen. Im ersten Teil erfolgt eine Systematisierung von Backdoors für kryptografische Verfahren, welche nur für den Angreifer effizient vom originalen Verfahren unterschieden werden können. Hierbei werden bereits bekannte Backdoors verallgemeinert, indem die Einbettung von Informationen getrennt von der Ausnutzung durch ...
