Attribute-Based Access Control for Multi-Authority Systems with Constant Size Ciphertext in Cloud Computing被引量：16
《China Communications》2016年第2期146-162,共17页CHEN Yanli SONG Lingling YANG Geng 
supported by National Natural Science Foundation of China under Grant No.60873231;Natural Science Foundation of Jiangsu Province under Grant No.BK2009426;Major State Basic Research Development Program of China under Grant No.2011CB302903;Key University Science Research Project of Jiangsu Province under Grant No.11KJA520002
In most existing CP-ABE schemes, there is only one authority in the system and all the public keys and private keys are issued by this authority, which incurs ciphertext size and computation costs in the encryption an...
