Cloud storage accommodations have become increasingly popular. Because of the paramountcy of privacy, many cloud storage encryption schemes have been proposed to forfend data from those who do not have access. All such schemes surmised that cloud storage providers are safe and cannot be hacked; however, in practice, some ascendant entities (i.e., coercers) may force cloud storage providers to reveal utilizer secrets or confidential data on the cloud, thus altogether circumventing storage encryption schemes. In this paper, we present our design for an incipient cloud storage encryption scheme that enables cloud storage providers to engender convincing fake utilizer secrets to forfend utilizer privacy. Since coercers cannot tell if obtained secrets are true or not, the cloud storage providers ascertain that utilizer privacy is still securely forfended.
