• W1601791261 abstract "Storing data in the cloud offers a scalable and easy way to handle large amounts of data guaranteeing availability and scalability by the hosting Cloud Service Providers. The price for the gained availability is uncertainness about the integrity and confidentiality of the data. Even if common approaches provide high availability and end-to-end encryption necessary to achieve Availability and Confidentiality as security goals, other security requirements like Integrity and Accountability are neglected. The key management of those clients for encrypting data to satisfy Confidentiality must furthermore support join-/leave-operations within the client set. This work presents an architecture for a secure cloud gateway satisfying the common security goals Availability, Confidentiality, Integrity and Accountability. Mapping these security goals, XML as storage base is equipped with recursive integrity checks, encryption and versioning based on the native XML storage Treetank. A Key Manager extends this approach to provide the deployment of multiple clients sharing keys to the storage in a secure way. New key material is pushed to a server instance deployed as Platform-as-a-Service (PaaS) propagating this update to the clients. The server furthermore applies integrity checks on encrypted data within transfer and storage. Any communication between client, server and Key Manager relies on fixed defined workflows based upon web services. The proposed architecture called SecureCG thereby enables collaborative work on shared cloud storages within multiple clients ensuring confidentiality, consistency and availability of the stored data. I. MOTIVATION OF SECURE CLOUD STORAGE The flexibility of Cloud Based Services offers great possibilities to store any data in a guaranteed available and scalable manner. All data peculiarities ranging from block based byte chunks to Microsoft Word-documents are thereby persisted in the cloud. Cloud Storage Gateways represent convenient applications mapping such interfaces to common Cloud Service Providers. Most Cloud Storage Gateways thereby appear as standalone clients or centralized web applications. Even if Cloud Storage Gateways enable the power of Cloud Based Services to different kinds of clients, the gained Availability comes at a price. While Availability and Confidentiality are provided by the hosting of the encrypted primary data on Cloud Service Providers, Integrity, Confidentiality and Accountability are not sufficiently considered in existing approaches. Another drawback of current approaches is the dependency of Cloud Storage Gateways to the platform they run on, e.g. they are shipped as complete operating system images, hard coded in routers or delivered as platform dependent applications. Flexible usages representing libraries, server based infrastructures or user specific clients are not supported. A more flexible usage includes collaborative use cases and related distributed environments. Even if Availability and Confidentiality are already provided, the related key management must be adapted to satisfy this usage. Common centralized access controls use the same key for all authorized clients which complicate modifications on the set of authorized clients. Besides the necessary protection of the data from unauthorized access of excluded clients, updated key material must be propagated to the valid clients in a scalable and secure manner. An XML based architecture as Cloud Storage Gateway named SecureCG satisfies all security requirements, platform independence and flexible key management. Based upon the native XML storage Treetank [3], any data is wrapped on demand into XML[13] and persisted afterwards in the cloud. The underlaying tree structure enables SecureCG to provide easy ways of integrity checks supporting the security goal of Integrity. The Accountability is guarded through the native versioning of XML within Treetank. Encryption on the data satisfies the goal of Confidentiality whereas the underling tree structure of the XML plus the provided versioning functionality is exposed. SecureCG supports flexible handling of multiple Treetank clients with unique de-/encryption keys using a standalone Key Manager and the VersaKey approach[12]. Equipped with the platform independent, block based interface jSCSI [7], and the adaptive REST based interface JAX-RX[4], the client provides a flexible and secure storage interface. The storage itself is encapsulated by a server deployed as Platform as a Service(PaaS) implementation. The PaaS implementation provides own integrity checks to ensure Integrity within the transmission and the storage of the data. Even if the server only stores encrypted data to ensure Confidentiality on Cloud Based Services, the server also checks and propagates new encrypted keys within the authorized client set. Communication between client, server and Key Manager relies on web services with defined workflows. Within this distributed architecture and as a consequence thereof the scattered functionality, SecureCG fulfill the security requirements even on untrusted storage while working with all different types of data. Treetank as the base of SecureCG implements already the Accountability and partly the Confidentiality and the Integrity." @default.
