Encrypted File Systems
Hlavinka, Michal ; Nagy, Jan (referee) ; Hanáček, Petr (advisor)
This thesis is about encrypted filesystems and is aimed mainly for Linux solutions. At first there is explained why is it necessary to encrypt your data at all. Next is written about pros and cons of encrypting methods such as whole disk encryption, partition encryption, container encryption and file encryption. After the introduction there are mentioned most common security issues which can help attacker to decrypt your data or modify them. Furthermore this thesis contains short description about the most often used encrypted filesystems. There is also small how-to for the most important encrypted filesystems available in Linux and comparison of their speed. Next part of this thesis contains dm-crypt and LUKS description. In the last chapter all information are concluded. There is also mentioned benefit of this work and possibilities, what can be done in future.

Is Information On Secure Hard Disk Drive Only
Yours?
Arm, Jakub
This paper focuses on security of information saved on hard disk drives using encryption. The posibilities of information protection are outlined. Security of using AES cipher algorithm is discussed and some possible attacks are described. Regarding these attacks, some of them are serious threat, for instance, side channel attacks. Some possibilities how to avoid these attacks are demonstrated. Cipher filesystem, as the file cipher tool, is also presented. Among them, EncFS is introduced in greater detail and its use on cloud server is pointed out.
