摘要

摘要现有的大多数强指定验证者签名（SDVS）方案的安全性都是基于单个密码难题。尽管这些方案在今天看来是安全的，但对手在未来有可能找到解决这个问题的方案，如果发生这种情况，那么这种SDVS方案将不再安全。我们开发了一个新的基于混合问题的SDVS方案；因子分解和离散对数。新开发的方案比以前指定的SDVS方案提供了更高的安全级别，并满足SDVS方案的安全特性和要求。

A Strong Designated Verifier Signature Scheme with Hybrid Cryptographic Hard Problems

Abstract The security of the most of the existing strong designated verifier signature (SDVS) scheme are based on a single cryptographic hard problem. Although these schemes seem secure today, there is a possibility for an adversary to find a solution for this problem in the future and if this happens, then such SDVS schemes will no longer be secure. We develop a new SDVS scheme based on hybrid problems; factorization and discrete logarithm. The new developed scheme provides a greater security level than those previous designated SDVS schemes and satisfies the security properties and requirements of a SDVS scheme.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
