Cloud computing promises significantly change the way we use computers and access and store our personal and business information. With these new computing and communications paradigms arise new data security challenges. Due to the low maintenance, Cloud Computing provides an efficient solution for data sharing among cloud users. But due to frequent change of membership, the sharing data in an un trusted cloud is challenging. We consider the problem of building a secure cloud storage service on top of a public cloud infrastructure where the service provider is not completely trusted by the customer. We are describing several architectures that combine recent and non-standard cryptographic primitives in order to achieve our goal. In addition we analyses the security scheme of our scheme with rigorous proofs and demonstrate the efficiency of our scheme in experiment.
