WebDec 5, 2024 · Proof of Retrievability (PoR) Many people outsource storage by uploading their data (like music, photos, and documents) to remote servers for reliability and easy accessibility from many devices, including mobile phones and laptops. These users are at the mercy of their storage providers and have to trust the servers. Web几乎与POR同时,Ateniese等人提出了可证明数据持有(Provable Data Possession,PDP)模型[2].PDP通过检查一个小的采样数据块完整性,来判断更大数据的完整性.但是,此方案计算开销较大.在数据异地容灾能力验证过程中,可能需要对较大的数据进行完整性验证,采用PDP方法会消 …
