基于联盟区块链的高校数据平台安全共享研究OA北大核心CSTPCD

In order to break the data island and ensure that colleges and universities data sharing between various departments will not be accessed illegally,a method of colleges and universities data platform secure sharing based on alliance blockchain is proposed.After analyzing the technical architecture of colleges and universities data platform sharing under the alliance blockchain mode,a colleges and universities data platform secure sharing mechanism based on alliance blockchain smart contract is designed.In this mechanism,a method of data secur sharing based on improved RSA encryption algorithm is used to provide data encryption services for data publishers and data decryption services for data demanders.The data sharing transaction between both parties is mainly completed by means of the alliance blockchain smart contract.The smart contract can conduct data sharing transactions without third-party intervention in accordance with the authorization results of encryption and decryption information and sharing constraints of the affairs data sharing.After testing,it is found that when the proposed method is used for the colleges and universities data sharing,the data transmission rate can be increased and the number of illegal extraction of school affair data is 0.
