A Novel Physical Layer Key Generation and Authenticated Encryption Protocol Exploiting Shared Randomness
… the physical-layer. The topic of physical layer authenticated encryption using high rate key generation through shared randomness is investigated in this work. First, a physical layer secret key generation scheme is discussed exploiting channel reciprocity in wireless systems. In order to address …

Analysis and Design of Symmetric Cryptographic Algorithms
… In the second part of the thesis, we focus on authenticated encryption schemes. While regular ciphers only protect privacy of processed data, authenticated encryption schemes also secure its authenticity and integrity. Many of these ciphers are additionally able to protect authenticity and …

DEFY: A Deniable File System for Flash Memory
<p>While solutions for file system encryption can prevent an adversary from determining the contents of files, in situations where a user wishes to hide even the existence of data, encryption alone is not enough. Indeed, encryption may draw attention to those files, as they most likely contain …
