Cloud Data Integrity Verification Algorithm for Accounting Informatization in Shared Mode

In the sharing mode, the research on the cloud data integrity verification algorithm of accounting informatization is mainly to encrypt the data to ensure its security in the transmission process, so as to ensure the safety and reliability of accounting data in accounting informatization. In order to solve this problem, based on PKI technology, a cloud data integrity verification algorithm was proposed. The algorithm encrypts cloud data, and then uses symmetric keys to verify data integrity. The simulation results show that the proposed algorithm has high computing efficiency and strong anti-attack ability.
