Abstract: In cloud computing, users can not ensure that the data stored in the cloud storage server is complete. How to efficiently verify the integrity of user data is a hot topic in academic research. An improved scheme of data integrity verification by manipulating scheme of identity-based aggregate signature is proposed, the secret key of the user is used to compute the file tags, and the private key generated by PKG is used to calculate the signature of the user's encrypted public key and other information. Therefore the credibility and security of data integrity verification are enhanced. Finally, the effectiveness of the scheme is verified through the security and performance analysis.

Key words: data integrity, identity-based encryption, aggregate signature
