  • The safe data sharing in cloud, cipher text policy attribute based encryption is promising as data owner having full control over access policy of shared data. Together with the growth of mobile applications, mobile cloud services have been introduced as a potential trend in cloud computing. Existing research work hardly notices that mobile front-end devices, such as smart phones, are far more vulnerable than servers with respect to privacy protection. Thus, the vulnerability in private key protection may easily lead to the exposure of keys to unauthorized users. In addition, current ABE key management schemes also require much bilinear pairing calculation, exponentiation and multiplication, especially in the decryption step. The resulting run time may be horribly unacceptable. In this paper, we propose a novel collaborative key management protocol in ciphertext policy attribute-based encryption (CKM-CP-ABE) aiming to enhance security and efficiency of key management in cloud data sharing system.
