Secure Cryptographic Technology Framework for Data Element Circulation Transactions

With the rapid development of the data trading market, the challenges to data security are increasingly prominent. This research begins with the entire process of data element circu1ation and transaction, analyzing the security needs of data production, storage, circulation, consumption, and other links, and proposes a comprehensive security cryptographic framework. This framework primarily covers five aspects: storage security, consumption security, transaction security, management security, and privacy security. The study not only thoroughly analyzes the security risks in the entire process of data element circulation and transaction but also proposes solutions based on cryptography, which is of significant importance for guiding practical data transaction security practices. Furthermore, the research delves into how to ensure the flexible use and value mining of data while protecting data security, providing theoretical support and technical guidance for the healthy development of data element circulation and transaction.
