大数据环境下支持多关键字的可搜索公钥加密方案
A public key encryption with multiple keywords scheme for big data
摘要
Abstract
The continuous improvement of information technology will inevitably promote the arrival of the era of big data.Cloud computing provides a powerful data processing platform for big data.However,data security and privacy issues have aroused great concern.In this paper,we propose a new certificateless public key encryption scheme with multiple keywords search and free of secure channel for big data.We also prove that the proposed scheme can resist chosen keyword attack in random oracle model.The performance analysis shows that,the proposed scheme reduces the computation cost as well as the communication cost compared with the scheme proposed by Peng et al.in 2014.关键词
