A Consensus Framework for Reliability and Mitigation of Zero-Day Attacks in IoT

Algorithm 1

Strategic decision on retrieved context.

  Input: , , , , , , , ,

  Output: context decision

Register IoT devices with CDS, SDS, LDS

set

  while    do

set a periodic counter for evaluation

Retrieve context from IoT device

Form

Mark input and outputs

Initialize context table

 if    &&    &&    then

Mark the device

Check with CDS, SDS, LDS

Analyze , , , , , ,

Update context table

Generate alert messages (context table)

Follow consensus data sharing protocol

else

Continue

end if

Operate till trust is not ensured

  end while
