Software Architecture of JTAG Security System
Authors: , ,
Abstract: The issue of JTAG security has recently become of interest not only to academic researchers but also to industrial entities. As a response to this security need, several security approaches using fuses, key matching, and three-entity authentication approaches have been proposed. However, each of those solutions only provides the idea of the security mechanism or implementation of the hardware part of the security solution without thinking of how the user can access such a solution in an effective manner in terms of ease of use, administration, and practicality. In this paper, we share our experience in developing a real-life complete software solution for a JTAG security system. The proposed software solution provides benefits such as ease of use/administration, complete functionality, scalability, maintainability, and practicality. This work also shows how a user-specific software solution can overcome the limitations of commercial applications and improve the efficiency of special processes.
