摘要
Abstract
In the multi-authorization attribute-based encryption scheme, each authority will send a private key to the user.When the user to get all the private key but can not be successfully decrypted, the authority does not know which is the corresponding private key error, it can only ask all authorized agencies to re-send time, so that a waste of time and waste of resources.In order to solve the above problems, a multi-authorization attribute-based encryption scheme with key verification is proposed.This method can verify the correctness of the private key under the matrix access structure,and solves the problem that a large number of authorized institutions need to retransmit the private key when the legitimate user can not decrypt successfully.At the same time, it realizes the anti-collusion attack and improves the security of the system.Finally, it is proved that the proposed scheme achieves the security of selective plaintext attack in the selective-set model.关键词
