The design of an electronic voting system has been a hot research topic in the area of information security. Based on ID-based ring signature, blind signature, multi-verification technology and existed typical electronic voting models, an improved anonymous electronic voting system is designed. We proved that the new system has good properties of security: anonymity, eligibility, fairness, nonr...

We propose a non-divisible electronic cash system that combines the restrictive blind signature technique and a batch signature scheme based upon the binary tree structure. Contemporary electronic cash solutions rely on the divisibility paradigm to achieve significant computational savings, and such techniques are considered to be the most efficient. We demonstrate an alternative approach that ...

Four years have passed since the EU directive on electronic signatures has been enacted by the European Union. By 2002, all EU member countries had to implement local legislation for electronic signatures. Development of products and applications in these countries so far, mainly focuses on signing with desktop PC’s on the basis of smart cards, issued by certification authorities. Several parti...

In paper-based workflow systems, signatures of individuals or groups of people have been used extensively for various purposes. Currently there are numerous studies on computerizing workflow systems. Also there are studies on implementing digital signatures in electronic media. But the diversified purposes of a signature in workflow makes a straight-forward implementation of digital signature s...

background: using primary tumor gene expression has been shown to have the ability of finding metastasis-driving gene markers for the prediction of breast cancer recurrence (bcr). however, there are some difficulties associated with the analysis of microarray data which led to poor predictive power and inconsistency of the previously introduced gene signatures. methods: in this study a hybrid m...

Digital Signature Act has been put into force since July 1999 to prepare a Infrastructure of secure and reliable electronic transaction in Korea. Korea Information Security Agency is the Root Certification Authority, which has four Licensed Certification Authorities subordinately, as of August 2001, approximately 900,000 certificates has been issued to be used in the area of internet banking, e...

With 123 million Internet users, China represents a phenomenal potential market for e-business. The astounding success of China in attracting foreign direct investment (FDI) can be partially explained by a series of reforms of policies, regulations, and laws. Can the introduction of China’s new electronic signatures law produce the same results for e-business in China? This paper analyses the e...
