Other Parts Discussed in Thread: CC2650, Z-STACK
Hello,
Physical Attacks -
This type of attack is the most common and involves tampering with the devices in the ZigBee devices by locating it. In fact, hard coded encryption key which might be loaded into the RAM memory are often employed by many radios operating on the ZigBee network, once the device is powered. Now, as these devices in the network are distributed and flashed, the probability of replacing these keys are very less and having known these issues, the attackers can set up special serial interfaces in order to intercept the encryption key in the ZigBee device when the power rises from flash to RAM. There are various low-cost devices like Bus Pirate and GoodFet which can be used for the above-mentioned exploit, thus proving the entire ZigBee network detrimental.
How to prevent cc2538 and cc2650/2652 based devices from these kind of attacks?
