Energy-Efficient Hash Chain Traversal
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2011 A hash chain H for a one-way hash function h(·) is a sequence of hash values , where vn is a secret value, vi is generated by vi=h(vi+1) for i=n-1,n-2,...,0 an0d v0 is a public value. A hash chain traversal algorithm T computes and outputs the hash chain H, returning vi in time period (called round) i for 1≤i≤n.
