CC2538: preventing Denial-of-Service attack on zigbee devices

Guru 14820 points
Part Number: CC2538


Hello,

Denial-of-Service There are numerous methods other than the one mentioned above to disrupt the ZigBee network thereby rendering it unsafe. Signal jamming, reflexive jamming, maximization of frame counter , reflexive jamming, maximization of frame counter are to name a few. Maximizing the frame counter is one of the most common examples of DOS in a ZigBee network, where the MIC is not verified and the frame counter is set to the maximum possible value, thus using the frame counter to ignore legitimate data packets. In this case, even if the contents of a packet transmitted are unintelligible and meaningless still the frame counter value will be accepted. Now the legitimate data packets received after the malicious packets with lower frame counter value will be ignored

what are the other denial of service attack apart from below mentioned -

1) Signal jamming

2)  reflexive jamming (I don't know what kind of  this attack is and how critical it is) 

3) maximization of frame counter(I don't know what kind of  this attack is and how critical it is)
