Is Information On Secure Hard Disk Drive Only Yours?

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
