A Novel Approach Using Advanced Encryption Standard to Implement Hard Disk Security

摘要

The objective of the paper is to develop an proficient and economical method for Hard Disk Drive(HDD) Security. The task is implemented using Full Disk E ncryption (FDE) with Advanced Encryption Standards(AES) for data security of Personal Computers(PCS) and Laptops . The focus of this work is to authenticate and protect the content of HDD from illegal use. The paper proposes a novel approach for protecting a HDD based on Partial Disk Encryption(PDE) which one of the flavour of FDE. The proposed method is labelled as DiskTrust. FDE encrypts entire content or a single volume on your disk. Symmetric key uses same key for encryption as well for decryption. DiskTrust uses these two technology to build cost effective solution for small scale applications. Finally, the applicability of these methodologies for HDD security will be evaluated on a set of data files with different key sizes
