Deleting Secret Data with Public Verifiability

A Joint Random Secret Sharing Scheme with Public Verifiability

In this paper, we propose a joint random secret sharing scheme with public verifiability. It is practical in distributed environment. Utilizing additive homomorphism, a random secret will be corporately constructed by some participants, which avoids the need for a mutually trusted dealer. In addition, we explore the technique of homomorphic verification and that of bilinear pairing to allow eac...

Improvements on Efficient Dynamic Provable Data Possession scheme with Public Verifiability and Data Privacy

An efficient Dynamic Provable Data Possession scheme with Public Verifiability and Data Privacy was recently published in ACISP’15. It appears that three attacks menace this scheme. The first one enables the server to store only one block of a file m and still pass the data integrity verification on any number of file blocks. The second attack permits the server to keep the old version of a fil...

Efficient Dynamic Provable Data Possession with Public Verifiability and Data Privacy

We present a Dynamic Provable Data Possession (PDP) system with Public Verifiability and Data Privacy. Three entities are involved: a client who is the owner of the data to be stored, a server that stores the data and a Third Party Auditor (TPA) who may be required when the client wants to check the integrity of its data stored on the server. The system is publicly verifiable with the possible ...
