Along with variant advantages, cloud storage also poses new security challenges. Potential users are reluctant to move important and sensitive data to cloud unless security challenges have been well addressed. This paper reports our on-going efforts to address three data security issues in cloud storage: repudiation, fairness, and roll-back attacks. We proposed a novel fair multi-party non-repudiation (MPNR) protocol, which provide a fair non-repudiation storage cloud and is capable of preventing roll-back attacks.
