Encryption And Portable Data Storage

Abstract

The protection of data is key issue in todays world. The wide of availability and use of portable technologies such as USB flash has increased concern about securing the data resides on these devices. Because USB flash drives are small, relatively inexpensive, and easy to use, the security of the information stored on these thumb drives is on-going concern. A number of approaches to safeguarding the information stored on these drives are available. This paper examines one approach to this goal through the use of encryption. This method encrypts all the data on the drive. In addition the fact the data on the drive is encrypted is not visually obvious when viewing the contents of the disk. The proposed approach uses publically available and free encryption algorithms. A user password is needed to view and access the data that has been encrypted. The proposed methodology is quick and easy to use. Individuals who routinely carry around their USB drives need to be able to decrypt and encrypt the device quickly and conveniently. Furthermore, if the device is lost, it is still possible with the method advocated in this paper to include information about how to return the device to the owner without compromising the secured data on the drive. Without encrypting the data on portable drives, the user risks the disclosure of information. This paper argues that portable storage should be secured and suggests a way to secure the data through password and encryption that further enhances the usability and flexibility of the USB flash drive. The paper includes the results and analysis of an undergraduate student survey that determined what habits and practices they followed with respect to securing their personal data and files. Some of the questions included in the analysis are the following:Do you encrypt your USB flash drive?Do you use any type of security for your USB flash drive?How important do you think security is for a flash drive? (A Likert scale)Do you use passwords to protect your USB flash drive?Do you backup your work?Do you think it is important to use security when using a USB flash drive?The findings of the survey help to understand the perspective of todays students and how to address the critical need to secure their information and data files with them.
