Abstract : Privacy, Security and Access Control are some of the challenges while sharing of physical resources among un trusted tenants. An anonymous authentication in cloud ensures that cloud users remain anonymous while getting duly authenticated. We propose a digital signature based authentication scheme with key management where Key Distribution Centers are decentralized in manner. A Key Policy Attribute based encryption scheme along with asymmetric key cryptosystem is used for encrypting the data that is stored in the cloud. To provide access policy Extended Attributed Control Markup Language (XACML) is used. Moreover, data stored in cloud is vulnerable to losses or corruption in order to overcome this, an automatic retrieval mechanism is used. Keywords: Cloud Computing, Data Storage XACML Access Policy Decentralized Key Distribution Center
