[SND]Hackable High-Tech Locks Pose National Security Risks - Page 3

post #21 of 22
True that all locks can be compromised, but it is a bit disturbing that there are so many methods, so easily executed to compromise this lock.

A rare earth magnet on the side pops the tumblers? What now?

There are benefits to using an electronic system, but why not have it backed up by a physical system also? Electronic based access to the physical lock. I would hope that any door leading to anything truly important would have several independent deterrent and monitoring systems.

Most fully electronic locks follow simple flaw designs. A lot of them have a problem where they minimize materials, this causes the PCB to be on the outside. The problem with this is that if you know electronics enough there is ALWAYS a 1/0 somewhere that unlocks that device. =( The better ones have the interface on the outside with minimal wiring PCB. By interface I mean anything from a card key to thumb prints. Every tumbler lock can be picked with ease. The bump key is the basic design behind the key gun, kinetic force to separate the tumblers. Standard picking has you align the tumblers one by one and using inherent flaws in the cylinder to be able to align them up one by one.

I used to be huge into cracking locks and safes. Safes work a lot better because the mechanics are secure and you literally have to know where to drill/access the internals if you want to force it. You can listen for the tumblers too though. Dampening helps this and can (in some cases) force you to require extremely sensitive mic equipment. If you couple that with an extremely tough exterior it makes it hard to "crack" the safe.

Basically lock security is terrible these days, the basic design is horrid. The advanced methods work but who's going to spend money on an high end electronic lock? [edit] Double keys work well as a standard deterrent, as well as a lot of car locks. The problem with car locks in terms if ignition is they are extremely easy to hot-wire. The key mechanism though is very craftily made for physical locks. I haven't gotten into picking those, no point as you can wire it. =P
