The data security exchange system should not only provide users with as much convenience as possible, but also ensure the security of the network system. In this paper, the network security data exchange management system is studied and designed by using blockchain. Combining data exchange with blockchain can prevent data from being maliciously tampered with, and can effectively solve the single point of failure caused by centralized management of data in the current data exchange scheme. The overall technical architecture of the network security data exchange management system is divided into application layer, contract layer, data management layer and blockchain layer to realize the integration of security protection and supervision. Because the Internet data set occupies a large space, this storage method brings a problem, that is, the data may be stolen by some hackers with ulterior motives. Therefore, this paper uses the key conversion mechanism of proxy re-encryption to avoid generating a new key for each data exchange. Through the system test, the function of the whole network security data exchange management system based on blockchain meets the system function design objectives and application requirements, and the performance meets the technical requirements of system operation.
