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

Efficient Sealed-bid Auction using Hash Chain

2001
This paper proposes the first sealed-bid auction method which uses only hash function. We use a hash chain to commit a bidding price. By using the hash chain, we can drastically reduce the time needed for bidding and opening bids. If we use a practical hash function e.g.

Multi-dimensional Hash Chain For Sealed-Bid Auction

2004
Sealed-bid electronic auction is an electronic auction where each submitted bid can be opened only after the closing time of the bid. A number of hash-based approaches were proposed which have advantages over non hash-based approaches due to the simplicity and efficiency of hash.

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).
