Weighted One-Way Hash Chain and Its Applications

2000
An one-way hash chain generated by the iterative use of a one-way hash function on a secret value has recently been widely employed to develop many practical cryptographic solutions, especially electronic micropayment schemes. In this paper, we propose a new concept called a weighted one-way hash chain. We then proceed to use the new concept to improve

Scalable Hash Chain Traversal for Mobile Devices

2005
Yaron Sella recently proposed a scalable version of Jakobsson's algorithm to traverse a hash chain of size n. Given the hash chain and a computation limit m (k=m+1 and (b = $\sqrt[k]{n}$)), Sella's algorithm traverses the hash chain using a total of kb memory. We improve the memory usage to k(b–1).

On The Computation-Storage Trade-Offs of Hash Chain Traversal

2003
We study the problem of traversing a hash chain with a constant bound, m, on the number of hash-function evaluations allowed per each exposed link in the chain. We present a new, general protocol that solves this problem, and prove that its storage requirements are $k\sqrt[k]{n}$ chain links, where k = m + 1.
