一个安全可追踪的策略隐藏属性基加密方案
A SECURE AND TRACEABLE ATTRIBUTE-BASED ENCRYPTION SCHEME WITH ACCESS STRUCTURES
摘要
Abstract
Referring to the problem that the traditional attribute-based Encryption schemes could not trace the malicious use and hide access structures at the same time,and the shortage that length of ciphertext and secret key increased with the number of attributes and large computing in decryption,large researches were put into several attribute-based encryption schemes with traitor tracing and hidden access structures separately.Combined with secure signature mechanism and the method of multi attribute value,a ciphertext-policy attribute-based encryption scheme supporting traitor tracing and hidden access structures was proposed.Based on the decisional bilinear Diffie-Hellman (DBDH) assumption,the scheme was proved fully secure.Moreover,it achieves constant size of private key and ciphertext and constant number of pairing computations.关键词
