Since the commonly⁃used cloud storage data integrity verification scheme can′t meet the requirement of data vali⁃dation,the cloud storage data integrity verification scheme ECPDP based on elliptic curve is put forward. The elliptic curve schemes of cloud storage data integrity verification with two⁃party participation,three⁃party participation and dynamic verifica⁃tion were designed respectively. And then the performance comparison experiments for the traditional PDP and ECPDP cloud storage data integrity verification schemes were performed based on OpenSSL code library. The experimental results show that the ECPDP scheme is better than the traditional PDP scheme in the aspects of protocol pretreatment performance,verification performance and challenge performance,and has high protocol safety.%针对当前常用的云存储数据完整性验证方案已无法适应数据验证需要的问题，提出了基于椭圆曲线的云存储数据完整性验证方案ECPDP，分别设计了二方参与、三方参与和动态验证的云存储数据验证的椭圆曲线方案。然后基于OpenSSL密码库对传统PDP和ECPDP云存储数据完整性验证方案进行了性能对比实验，实验结果表明，ECPDP方案在协议的预处理性能、验证性能及挑战性能方面均较传统的PDP协议有所提高，且不降低协议的安全性。
