You can not insert the random bytes from outside the source. The block of bytes itself must be present in the source files, and inserted at compile time. Every coder and reviewer will see the bytes.Rahul Mehta wrote: BEL says that only 3-5 people know the code. Also, code review would mostly involve source code review and not the compiled code and surely not the random bytes.
There is no way around it.
You can not send material "off the record". The shipper, customs, local shipper, receiving stores, accounts, everyone verifies the received quantity against the purchase order.errr ... the 100k tempered chips are sent "off the record". I did not say that Hitachi sent two boxes marked as "good chip - to be used for testing" and "tempered chip - to be used in PCBs".
Where? His house? How will the shipping and import documents will be made? Who will do the clearing? In whose name? Do you know that the chips are packaged 1000 to a box, each of them more than a cubic foot in size? So, the courier guy will deliver the 100 boxes to the BEL chief's home, and he will carry them in his pocket?And the tempered are not sent directly to BEL but sent to BEL chief.
This is moving from ridiculous to bizzare. Enough said.And later he got actual boxes replaced with tempered chips with the help of key people in the store area. Only 3-4 people are needed here. The people in store are wont even notice which boxes go and come, as long as they have gate passes.
No need to take things out of context. The original point was it is detectable. All you need is to hit ONE tampered machine to find it.Possible? Pls get Supreme Court order to examine some 10000 EVMs' gate level design. Is that possible for you?
The chips, whatever comes to the stores, are sample tested, so any modified chips are going to get caught.Power is tested during chip testing and NOT after PCB is made. After PCB is made, there are too many components that draw power and so unless something is way too much off, no one will bother. And also, power testing is done, but if addition in circuit is just 1%, then increase in power will be also just 1% and will pass within tolerable limits. So unless gate level design was tested, power test will not give any indications.
You continue to make out of the world claims that 100 boxes full of chips will be sent to BEL chief, and he will bring them into the stores. All those are IMPOSSIBLE. There is only one way to get the chips in, and that is through the normal channel. All those chips are going to get sample tested.
It is physically impossible to send, recieve, transport, and insert the huge quantity of chips clandestinely. We are talking about 100 boxes, each 1 cuft in volume.1. ??? CIA made duplicate chips and sent them to BEL chief. Big deal !!
It is logistically impossible to send a shipment to a person, without a logistics trail, including PO, import and shipping documents etc.
It is systematically impossible for the top guy of abig company to walk in into a stores with some material.
That is the big deal.
The titles (also known as designations) are given. Their job functions are self explanatory from the title. Use them.2. In the process babal you posted, you have not posted people in-charge of store area. Also, you have only mentioned titles and salaries, not given job descriptions. Essentially, the person in storage area have to change the boxes. I dont know the exact designations BEL uses for them
You don't need to know the BEL designations. We are debating based on the system I posted. Use them.
The truth is, you say numbers like 3-4, 6-8, but when it comes to real situation where actual job specifications are involved, the actual counts go way overboard. So, you are trying to make feeble excuses of not having "designations", where you yourself mentions "titles" are given.
Own up, man. You lost it.
No, they do not, and they can not.Once again, I want to re-confirm : Do chips have serial numbers inside them?
