Given an n-node undirected simple graph G and a positive integer k, the k-connectivity labeling problem for G seeks short labels for the nodes of G such that whether any two nodes are k-connected in G can be determined merely by their labels. For k = 1, an optimal solution to the problem is to give each node in the same connected component of G a common 驴log2 n驴-bit label, uniquely chosen for this connected component. For k 驴 2, Katz, Katz, Korman, and Peleg gave the first nontrivial solution to the problem, requiring O(2 k logn) bits per node. The best previously known solution, due to Korman, requires O(k 2logn) bits per node. We give the first asymptotically optimal solution to the problem, requiring only $(2k-1)\left\lceil\log_2 n\right\rceil$ bits per node, which matches a lower bound 驴(klogn) proved by Katz, Katz, Korman, and Peleg.
