Abstract

In the twenty-first century, people are accustomed to using computers to deal with their daily work and personal affairs. However, in an increasing number of computer applications in various fields, the security issue has become very important. By "secure", we mean secrecy and tampering detection. Therefore, the issue of how to guaranty the security of computer applications comes up naturally. We need more secure and dependable software systems to provide stronger protection of our sensitive data. This thesis presents CINDI Secure File System (CSFS), which is based on the implementation of two secure systems. One is a simple Secure Database Management System (SGDBM), which deal with data and metadata uniformly. The Secure DBMS is based on the GNU Database Management System (GDBM) in Linux. The GDBM is transformed to be a secure database system by embedding encryption and hashing. The other is a Secure File System that is based on SGDBM previously mentioned. CSFS uses the SGDBM to store file passwords for the encrypted files. It provides a number of commands, which can be used in the same way as other basic commands in Linux, and a simple GUI application for the secure file operations.
