Challenge of encryption technology for self-governing openness of data

Abstract

Data box is the basic data unit opened to the data users in self-governing openness of data,so the prevention for the degradation of data scarcity and the disclosure of privacy is mainly aimed at the data box.A data box may contain photos,videos,text and structured data,etc.The traditional data encryption technology cannot be effectively applied.The requirement of data encryption for data box and the challenges of traditional data encryption technologies were analyzed,and the prospect of new encryption technologies for self-governing openness of data was discussed.
