Improved Prototype Scheme of PETKS and its Expansion
Lei Feng-yu · 2009
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.
