Undoing Complexity - From Paper Clips to Ball Point Pens

Presented at The Last HOPE (2008), July 18, 2008, 6 p.m. (60 minutes)

This talk will be a systematic approach to dissecting and disabling multiple layers of physical security in locks. In this presentation, the focus will be on embedded design defects in high security locks, and how their discovery translates into security vulnerabilities and the disclosure of such flaws. The attack methodology for high security locks will be reviewed. Demonstrations will include case examples, examining tolerance exploitation, code design analysis, and leveraging the interaction of internal components within a locking system to achieve different types of bypass. The application of this program in the development of covert, surreptitious, and forced methods of entry will be examined. Also discussed will be the concept of responsible disclosure upon the discovery of security vulnerabilities, and how this concept applies to both those who discover flaws and to the manufacturer that produces them, and why the same concept becomes a technical, logistical, legal, and financial minefield for manufacturers.
