基于广播加密的多策略非对称叛逆者追踪方案
A multi-policy asymmetric traitor tracing scheme based on broadcast encryption
摘要
Abstract
It was found that the scheme could not resist collusion attack and is similar to most schemes,its efficiency is very low because of relating to the quantity of users.In order to improve safety performance and to reduce the amount of computation,storage,communication,based on discrete logarithm problem,a new multi-policy multi-service asymmetric public-key traitor tracing scheme is proposed.The new scheme can be used flexibly in all kinds of domain because multi-policy broadcast has been realized by using different threshold value t.Compared to most typical schemes,the scheme has higher computation efficiency and shorter cipher text length,it also has stronger safety features since multi-service oriented, collusion resistance,full revocation,full recoverability,and black-box traceability can be realized.关键词
