Dynamic Cloud Audit Scheme Based on Homomorphic Hash Function and Virtual Index
摘要
Abstract
Aiming at the issue of cloud data integrity security and low update efficiency,a dynamic audit scheme based on homomorphic hash function construction was proposed.Firstly,the data was blinded to protect the privacy of the original data in the cloud.Subsequently,homomorphic hash algorithm was used to sign the blind data,which was beneficial to the calculation of signature aggregation.Then,the virtual index was introduced,which could be used to search and update specific data blocks quickly without af-fecting other data blocks.Finally,the scheme could be extended to batch verification to improve the effi-ciency of integrity verification in multi-user scenarios.Theoretical analysis showed that the scheme was safe and efficient.关键词
