Verifiable attribute base encryption scheme with multi-authority
|
Abstract:
Aiming at the security issues caused by the central authority in attribute base encryption, this paper proposed a noble multi-authority verifiable attribute base encryption scheme. Compared with other schemes, the central authority was omitted in this scheme which solved the problem that the whole system would crash once the central authority was destroyed, using the technology of making each authority to generate their own master keys parts as well as their public and private keys independently. So the security of the system was improved. At the same time,it verified the correctness of the ciphertext and the keys. In addition, it gave the verification and security analysis.
