Securing Applications in Personal Computers: The Relay Race Approach.

摘要

This thesis reviews the increasing need for security in a personal computer (PC) environment and proposes a new approach for securing PC applications at the application layer. The Relay Race Approach extends two standard approaches: data encryption and password access control at the main program level, to the subprogram level by the use of a special parameter, the Baton. The applicability of this approach is demonstrated in an original Basic application and an existing Dbase IV application, representing both third generation language (3GL) and fourth generation language (4GL) environments. The Approach can add to overall network security in the PC LAN environment as well. The Approach is successful and proposed enhancements can strengthen the Approach.
