An Agricultural Traceability Permissioned Blockchain with Privacy-Aware

As the blockchain technology maturing, data publishing platform based on blockchain also more and more. However, the privacy of the blockchain becomes one of the key problems. In order to solve the problem of privacy protection, the paper proposed a privacy-awake aggregate signature scheme based on the bilinear mapping. This signature scheme aggregates the signatures of multiple users, shortens the signature verification time and reduces the use of memory space. At the same time, in order to protect the privacy of users, this signature scheme uses pseudonyms to protect the real identity of users. In this paper, the privacy-awake aggregate signature scheme is applied to the permissioned blockchain, and a traceable permissioned blockchain data publishing platform with privacy-awake is designed. The platform can be applied to agricultural product traceability, realizing product traceability and the anonymous release of agricultural product and trading records.
