| Summary: | An efficient user revocable multi-authority ABE scheme was proposed,a “hybrid decryption key” for each user isused to achieve efficient user revocation.Comparing with the existing schemes,this scheme is more effective in user revocation.In addition,the scheme can also achieve user dynamic privileges management,partial data outsource encryption and ciphertext partially decrypted in the cloud server and shared data self-destruction after expiration. |
