Privacy-preserving certificateless provable data possession scheme for big data storage on cloud, revisited
作者：
Highlights：
• In this paper, we revisit the CL-PDP scheme proposed by Wang et al. in 2017 since their protocol is attacked in recent work of Liao et al. We modify their original scheme and hence obtain a twisted one.
• We also find out Want et al.'s security model is not proper because they merged the CSP and KGC into one entity. In our new security model, we prove that the twisted HKWWC-protocol is secure.
