چکیده

Recently, Liaw et al. proposed a hash based electronic traveler’s check system. They claimed that their scheme is secure. However, after analyses, we found that their scheme is vulnerable to key compromise impersonation and parallel session attack. Further, we will improve their scheme to avoid such an attack.

A NEW SECRET SHARING SCHEME ADVERSARY FUZZY STRUCTURE BASED ON AUTOMATA

In this paper,we introduce a new verifiable multi-use multi-secretsharing scheme based on automata and one-way hash function. The scheme has theadversary fuzzy structure and satisfy the following properties:1) The dealer can change the participants and the adversary fuzzy structure without refreshing any participants' real-shadow. 2) The scheme is based on the inversion of weakly invertible fin...

Digital Coins based on Hash Chain

We propose three digital coin schemes for doing electronic transactions over the Internet. These schemes are based on one-way hash functions. The rst scheme uses an ordinary one-way single hash function chain, which forms the basis of a simple micropayment scheme. The second scheme is based on a new technique called double-locked hash chain technique which overcomes some of the drawbacks found ...

An Improved Hash Function Based on the Tillich-Zémor Hash Function

Using the idea behind the Tillich-Zémor hash function, we propose a new hash function. Our hash function is parallelizable and its collision resistance is implied by a hardness assumption on a mathematical problem. Also, it is secure against the known attacks. It is the most secure variant of the Tillich-Zémor hash function until now.

A Universally Composable Scheme for Electronic Cash

We propose a scheme for electronic cash based on symmetric primitives. The scheme is secure in the framework for universal composability assuming the existence of a symmetric CCA2-secure encryption scheme, a CMA-secure signature scheme, and a family of one-way, collision-free hash functions. In particular, the security proof is not in the random-oracle model. Due to its high efficiency, the sch...
