%X <p>A scheme decentralizing multi-authority attribute based encryption DMA-ABE was proposed. In this scheme, the multiple attribute authority was used to issue users' keys without any coordination of central authority. Any linear secret sharing schemes access structure was supported, which is efficient, flexibility and fine-grained. The proxy re-encryption was used to realize on-demand attribute revocation and authorization. A security analysis was given to verify the scheme is secure against chosen plain-text attack.</p>
