摘要 伴随着云计算和存储技术的发展,越来越多的用户把自己的敏感数据存储在云服务器上,与此同时,用户的数据面临安全的考验,针对这种情况,为了更好的实现数据完整性验证技术,帮助用户更好的使用云存储服务,提出一种支持合作方式的数据完整性验证方法,通过引入分布式多TPA系统可以同时处理不同用户的数据验证请求,运用代数签名和同态标签的性质对数据进行审计,并且支持公开可验证。最后实验结果显示了该方法在数据完整性验证方面的性能和高效性。 More and more have chosen cloud for their storage demands for its low cost, high availability and reliability. In the meantime, a great challenge for data security is also brought in the spotlight, and some security incidents have decreased users＇ trust in cloud services. For this kind of situation, in order to better implement the data integrity verification technology, help us- ers to better use cloud storage service, In the paper, Put forward a way to support the cooperation of data integrity verification method, by introducing a distributed multiple TPA system can handle data validation request of different users at the same time, using algebra signatures and homomorl0hism tags to the nature of the audit data, and support the publicly verifiable.
