Hello my friends, I have new idea how to in certain cases lift this already perfect solutions level up in term of security. I have question to you more experienced lock experts, what if…..
What if we will made small mod to this Polish Combination Lock based on build in small traditional lock (tubular, pintumbler or any other). Can you imagine for a moment that we will treat Open Close knob as plug and the masking part as a case of this lock?
The masking part will have such a shape that it will not rotate at all. It will be fixed in the body of this padlock. There will be key hole in front of the open close knob and lets say 5 pins lock any type is proper here.
In order to rotate the Open Close you will need to insert the key and then after setting proper code just rotate and open. This additional lock could be very simple lock , chepest and simplest on the planet.
The beautiful part is that the attacker will need to pick this lock any time before checking the one code. In our case almost 10 000 000 Times picking :). This solution will protect this mechanism even more than now it is protected already with all features.
Of course this key lock will be additional option we will not replace any features like magnetic joint etc. All the previous features remain as on this video.
So the mod needs 1. Changing the masking internal shape, not full rounded but mounted in the body. 2. Adding some kind of small lock using OpenClose knob as Plug and the masking as the case of this lock.
This solution will rise this mechanism to TOP NOTCH and so secure that all attackers will not start even the picking. If you will know that each time you like to probe the code you need first to pick this small lock then you will not try it I think.
I need your help here to understand which type of lock should be mounted there as an ultimate security option. Thanks again for your feedbacks, Zbigniew
PS. This mod is just in the future locks maybe in doors and safes. Additional benefit of such a mod is more secure integration of the OpenClose with the rest of the lock.
I am very glad that the lock has been shipped so quickly. Now Swynndla has 7 days for playing with the lock and try to decode it using all methods he wants including cardboard and laser beam method.
I am pretty sure he will have fun and will check carefully if this time the upgraded mechanism is really decoding proof. In this case with 10 000 000 unique combinations really doesn’t matter if this is 7 days or more. Here is important that Swynndla can check new design and “make certification” of the security level of this lock.
As he mentioned in this video the lock is very scalable and it can have 7 or less wheels but in real world the attacker will rather try to open using brute force and destruction instead of decoding.
This is exactly my goal to design the lock that can be open only by destruction. That is pick and decode proof.
This is important as if this will be true we will have one of the most secure solution available on the market soon.
I wish Swynndla good luck as he has most experience in decoding my design. I am waiting for final review and judgment.
Here you can watch my new video showing 10 000 000 combinations padlock.
This prototype is ready for next decoding challenge. I claim that this padlock cannot be decoded even with laser not mention standard free hand methods.
I would like to announce next round of worldwide decoding challenge. The rules are the same as before. I count on Swynndla to take the challenge (he has priority) as he was the winner of first edition.
Please let me know Swynndla and I will send you this padlock for your attempt and review. You will have full 7 days to open this 10 000 000 combinations padlock :).
Today I have received the last model of my unique Polish Combination Padlock. It has been printed at Warsaw University of Technology in Rapid Prototyping Laboratory on Formiga P100 SLS printer.
Here is first picture of this 10 000 000 combinations padlock.
I need to adjust all details now to make them work smooth and it will be ready for testing.
After assembly I realized that this padlock is super complicated and very difficult to operate as you need to allign all 7 wheels. I think this is maximum security level (not necessary good for padlock) and next variants whould have less wheels. Nevertheless I made this one to proof that 7 wheels are possible to made.
The body of the padlock is very compact but massive and allow to use different shackles up to 14mm thickness. Current one has 10mm.
The numbers are very badly visible and need to be painted but are too small (concave) to do it correctly so I need to leave them as they are for testing. For sure the metal version must have super visible numbers.
The open/close knob is very tiny comparing to last models and this will complicate the operation and decoding as well. I think the user will use this just in case of opening/closing but attacker will have real pain to operate many times such a small knob.
I will make soon next video to show you this super secure padlock with all protection features inside incl. neodymium magnets.
Hello, today I found finally the way to protect the mechanism against laser or cardboard decoding attack.
You can see below the mechanism that will be use in the first full metal prototype of my Polish Combination Lock. It will be inside 10 000 000 combo padlock (7×10 numbers).
There will be two neodymium small cylinder magnets mounted inside the mechanism. They will work as an magnetic force joint between red wheel and green shaft. The red wheel will be not fixed with green shaft with the thread.
First one 4mm in diameter and 5mm height will be placed inside the central open/close shaft (green).
Second one with 3mm in diameter and 3mm height will be placed inside the new designed wheel (red one) half gear , half cylinder.
Both magnets will work together during normal operation however when you will try to use some extra force i.e. during the decoding attack they will dissconnect or misslead the attacker and the open/close shaft will rotate freely 360 degree. They will start dissconnect slowly so the laser method will show inconsistent results. This solution eliminate any rubber need or super accurate machine tollerances inside the gates.
This small mod solve in my opinion all potential decoding known attacks and make this mechanism top-notch secure.
