In this letter, we point out that the privacy-preserving adaptive trapdoor hash authentication tree scheme (published in IEEE TIFS, doi: 10.1109/TIFS.2020.2986879) can be invalidated by an adversarial cloud server: if the outsourced data is arbitrarily modified, the cloud server still can pass the third-party auditor’s auditing.

带有公共隐私保护审核的认证数据结构方案的密码分析

在这封信中，我们指出，对抗性云服务器可能会使保护隐私的自适应陷门哈希认证树方案（在IEEE TIFS，doi：10.1109 / TIFS.2020.2986879中发布）无效：如果对外包数据进行了任意修改，则云服务器仍可以通过第三方审核员的审核。
