Security of Hard Disk Encryption

Abstract: In order to provide confidentiality to digital information and safety to computer hard disk, encryption is considered to be best solutions. Now a day, several hard disks encryption software’s with a range of different features are commercially available. Majority of the software uses that encryption algorithm, whose cryptanalyses are already known. Now the vital question is that how much these encryption software’s provide security to the data. Any implementation and design flaw leave loop hole or backdoors in these softwares. Either by take the advantage of user unawareness or by using any external hardware, software’s security can be defeated by using smart and easy methods. This thesis will provide possible weaknesses and vulnerabilities of commercially available hard disk encryption software, who offering complete security to the hard disk data. This thesis will also access the real world performance of hard disk encryption softwares.
