PRISMACLOUD Tools: A cryptographic toolbox for increasing security in cloud services. reusable toolbox encapsulating cryptographic functionality from which dependably secure cloud services can be assembled. In order to provide a tangible abstraction of the complexity involved with the construction of cryptographically secured cloud services, we introduce the fourlayer PRISMACLOUD architecture. Top down, it consists of a use cases (application) layer, a services layer, a tools layer, and a cryptographic primitives and protocols layer.

Malleable Signature Library (MSSLib) is a Java library (MSS library) and part of the PRISMACLOUD FLEXAUT cryptographic tool that supports various types of malleable signature schemes for controlled modification of signed data and verifiable computations.

This tool supports the delegation of processing authenticated data in a way that the result can be efficiently verified for correctness. It comprises three different components, being a data originator component, a data processing component, and a verification component. The data originator component provides the input data (and potentially some additional metadata). The data processing component is given a set of input data and a description of the processing rules, and outputs the result of the computation, as well as a proof certifying the correctness of the delegated computation.

SPECS Framework is an open source solution devoted to create a reusable Platform-as-a-Service that offer Services granted by Security Service Level Agreements, Both framework and architecture can be integrated "as-a-Service" into real life Cloud environments, with a emphasis on small/medium/federated CSP and end users for service developers. This allows them to integrate SPECS’ SLA-oriented security mechanisms into existing cloud services.
