We agree that authorized distirbutors should be the first place buyers go for components. However, recently there was a situation where a franchise distributor shipped suspect counterfeit parts to two separate customers. It turns out the franchise distrubutor shipped parts that another customer had RMA'd - those parts were suspect counterfeit.

 

At the end of the day there is no way to eliminate human error. With that said, buyers and managers can make sure that they stay current with their audit schedules, utilize authorized suppliers and when parts are not available through authorized suppliers engage a broker who has been AS6081 certified or approved by the DLA.

On the surface, this integrated identifier seems like a good idea and one that has been tested in other industries for security. I find myself wondering, though, how long it will take the counterfitters to replicate the identifier to push through fake components. The problem always remains that the bad guys have the same technology as the good guys so they can stay a step ahead. Anyone one to take a guess and start a pool?

Adeniji: I completely agree. In fact, I think most buyers do rely on recommended suppliers -- or those that they know already.  The counterfeiting problem is so insidious that it goes much deeper than that.


Every once in a while, I get a $100 bill in my hands. Not often. But when I do, I realize I would never know whether or not it is counterfeit. And there are millions of those in circulation. There are probably hundreds of thousands of counterfeits. If people can't spot funny money, how is a fast-paced industry supposed to spot well designed counterfeit electronic components?

This is an interesting comment.

One approach to cut counterfeiting would be to adopt a business process that says that all parts must be sourced from authorized distributors. But counterfeits can be difficult to spot. They could be failed parts from an approved supplier that weren't destroyed and then diverted by criminals into the supply chain. Or, they could be lower-grade components repackaged to resemble more expensive devices.

Make it simple, to start, use Authorized Distributors and Manufactures. don't let CM's buy from where ever they want. We can't control the CM's owned by CHINA. Stop purchasing COTS product not made from an Authorized manufacturer. Start publishing where counterfeit units have been purchased from. 

They could be failed parts from an approved supplier that weren't destroyed and then diverted by criminals into the supply chain. Or, they could be lower-grade components repackaged to resemble more expensive devices. This statement is not likely, but I would be willing to this chance. The Authorized Distributor or Manufacture is not going to re-package the units. START SIMPLE. Remmber a shake of the hand, a non-disclosure agreement or sign Purchasing Agreement mean nothing to CHINA.

@tirlapur

Don,t you think its better to ask forthe list of highly recomemded suppliers than to ask for the list of high-risk suppliers.

It's a bit risky if you do not have access to the names of suppliers to be avoided especially  if you could not enlist all of them but a list of good suppliers will do a better job.

This is an interesting concept. I think other issues need to be taken into consideration, such as the distribution of the verifying software/tools has to be done via some secure channel as well.

That's a smart way to comabat counterfeiting. Can we do it for all the electronic devices? How about passives??

However the software which does the authentication could be vulnerable to tampering by malware.

@prabhakar_deosthali, I am not sure if software will have any impact on this.  I think its hard to mimic PUFs because they take advantage of inherent variations in manufacturing processes. I dont see how malwares can impact such inherent variations.

Must chips be powered-up in order to verify authenticity?

@owen, I think the chips must be powered-up else SRAM chips wont generate required patterns which is must to check the authenticity of the product.

 the number of high-risk suppliers increased by over 60 percent between 2002 and 2011.

@Peter, thanks for the post. I am curious to know where can companies find the list of high-risk suppliers so that they can avoid such suppliers ? Do we have any ratings given to the suppliers based on the risk factor ?
