【摘要】 关键字可搜索的公钥加密是对基于身份加密方案的直接应用,是一种具有特殊功能和全新应用环境的方案。2005年Abdalla等人首次提出了具有临时关键字可搜索的公钥加密的原型方案。在该原型方案的基础上,研究了该方案存在的效率问题,提出了一种更高效的实例方案,并从中抽象出更高效的原型方案。在原型方案的基础上,提出了两种扩展的原型方案,从而进一步丰富了该方案的应用环境。更多还原

【Abstract】 Public-Key Encryption with Keyword Search is an application of Identity-Based Encryption scheme,and an interesting scheme with special functions and new application.In 2005,Abdalla et al.firstly proposed a prototype scheme of Public-Key Encryption with Temporary Keyword Search,based on it,researched the efficiency of it,proposed a more efficiently instantial scheme,and extracted a more efficient prototype scheme from this instantial scheme.Based on this proposed prototype scheme,proposed two kinds of expansions,and then enriched the applications of this prototype scheme.更多还原
