Algorithm 3. Pseudo code for CON authentication

INPUT: Number of nodes, Target security level each node 1  iterate (node size increases): 2    set target security levels for all nodes 3    // each group of target levels has 4    // the same number of nodes of the ones of DAM4SNC’s) 5  while (until all nodes reach the target security level and transmit data): 6    randomly choose N (nodes to be authenticated) 7    Tn = Tn + 1 8    if Tn == target_level: 9     transfer datan OUTPUT: Latency
