Secure Cloud Storage: A Protocol for Remote Data Integrity Checking
Abstract
The integrity of files stored on servers is
crucial for many applications running on the internet.
Recently, many works provide data dynamics and/or
public verifiability to this type of protocols. Remote
data possession checking protocols permit checking
that, a remote server can access an uncorrupted file in
such a way that a verifier does not need to know
beforehand the entire file. In addition, both data
dynamics operations and public verifiability are
supported. Token pre-computation algorithm is used to
generate tokens. Challenge-Response protocol is used
for communication between the challenger and the
responder. Through a formal analysis, the correctness
and security of the protocol is shown. After that,
through theoretical analysis and experimental results,
we demonstrate that the proposed protocol has a good
performance.
