摘　　要：属性基加密方案虽然解决了信息在网络传播过程中出现的接受者身份不确定、人数不确定等问题,但由于在使用过程中每次都需要加密者把访问策略连同密文一起发送给接受者,而访问策略在一定程度上隐含了加密者和解密者的敏感信息。为了保密,本文利用矩阵构造了一个基于矩阵的隐藏访问结构的属性基加密方案。Although attribute based encryption scheme solves the information in the network transmission in the process of the receiver are not identified,the number of uncertain problems,but in use process need bitlocker every time the access strategy together with the ci-phertext is sent to the recipient,but access strategy to a certain extent,implied the bitlocker and decrypt sensitive information.For secrecy, in this paper,the use of matrix to construct a new kind of anonymous access attribute based encryption scheme.
