Firstly, a shared data integrity verification sheme which supports public verifiability in the cloud is analyzed. The analysis shows that the sheme is vulnerable to data recovery attack and integrity forgery attack, which bring the risk of privacy disclosure and integrity deception. Then, on the basis of this analysis, an improved sheme with security enhancement is proposed. Finally, the security analysis and performance analysis of this improved sheme are made. The results indicate that this sheme can keep the security and privacy of data storage while implement shared data integrity verification efficiently. Thus this scheme provides a higher level of security along with high efficiency.
