Information Leakage Prevented by Data Encryption using Smartcard
Journal Title: International Journal of Engineering, Science and Mathematics - Year 2012, Vol 2, Issue 3
Abstract
Information leakage has recently become a serious problem and most often a result of actions inside rather than outside the system that should be protecting the information. Although system administrators have high access authority, they should not know the disk encryption keys of users because they may not be authorized to read a user's sensitive information. Information leakage from a disk in a managed network (e.g., an enterprise network) is generally prevented by encrypting either the entire disk or just the confidential files stored on it. Since this encryption uses highly secure. Symmetric-key encryption algorithms, however, it is not easy for a user to memorize the random numbers constituting the disk encryption key. So it is important not only to encrypt the disk data but also to store the disk encryption key securely. This can be done by storing the key in a hardware token such as smart card or USB device, but there must also be some way to recover read it If the token is lost. For example, it is necessary to keep a backup copy in a safe place such as another key management server. The encryption key should not be known by the system administrator, however, nor should it be possible for malicious users within the system to recover a user’s encryption key. In this paper we present a scheme that can limit key recovery when a user loses his smart card and can do so.
