MULTILAYERED SECURITY IN USB DRIVES

Data security in USB or disks has turned out to be an important research issue in recent years, because of lack of efficient algorithms. As the technology is advancing many high performance computer are available in market, using which intruder can change or take the data from a disk or USB. This system is mainly designed for any person or organisation who wants to secure their data in Today’s World. This system mainly concentrates on two steps: first is to combine more than two algorithms for full disk encryption, second is to ask for encryption key or password when someone tries to decrypt it. The success rate has been tested on 5 sets of data entries of different size approximately, though the throughput of our algorithm is less but it is more secure than others. We have used AES with SHA-1 & integrated the BitLocker module along with these 2 algorithms. All these algorithms together provide sufficient security for any disk.
