Threshold secret sharing and its typical application
摘要
Abstract
Since secret sharing technology is an important branch in cryptography,it has plenty of research results in theory and application currently. (k,n) threshold secret sharing scheme divides secret information into n meaningless sub⁃secrets. Threshold secret information owns at least k sub⁃secrets,secret information can be recovered and its security can be enhanced greatly. On the basis of introducing the basic threshold secret sharing schemes,the typical applications in several important branches of cryptography,such as digital signature,based on identity encryption,based on attribute encryption and image en⁃cryption are concluded and summarized completely. Current problems of these applications are analyzed,and future research trends are prospected.关键词
