I can see why this would raise Apple's cost per cable/adapter - but why pass that cost on to us? They should eat it. I know ALL costs are passed on to the customer one way or another, but I mean in the cable itself.
This high price gives cloners a huge incentive to find a way around this (if it's possible).
Counterfeit accessories result in house fires and such. We don't want this crap thank you very much.
There's perhaps some wiggle room on things that don't electronically interface with the iphone, ipad, etc, but if it can risk destroying the device at either end, it needs to never leave China.
It won't be long until the tiny chip embedded in the cable will be more powerful than the computer used to land the lunar module (and that pooped out at the last minute or so, due to overload). Amazing.
I don't understand. Don't we WANT 3rd parties to be making accessories for our iPhone 5 and next generation iPads?
Sure, we want third party accessories. All encryption would do is make sure the third parties pay the proper license fees and have proper quality control.
Olivierl is right. CRC isn't a security feature, it's a way of ensuring data integrity. Which is important for a high speed cable whose entire existence is to transmit data from one end to another. As we approach the speed limits of what is possible over copper cable measures like this chip become necessary.
The wikipedia entry on CRC is good enough for introductory purposes.
