Abstract: Systems and methods for providing an S-box. The methods comprise: implementing a plurality of layers on a field programmable gate array, wherein each of the layers comprises a substitution sublayer and a mixing sublayer. The substitution sublayer comprises a plurality of ?-boxes that are each configured to perform a different randomly chosen non-linear bijective mapping from GF(24) to GF(24). The mixing sublayer is configured to (i) compute a plurality of product terms each representing a product of an element of a maximum distance separable matrix M and an output from one of the plurality of ?-boxes, and (ii) compute a plurality of column vector elements each comprising a sum of respective ones of the plurality of product terms.

Abstract: A method and a system to create a software test environment on demand are described. An example system includes a dependency module to, upon receiving a command identifying a primary function to be created in a test environment, identify one or more dependencies of the primary function. The dependencies are other functions or databases that the primary function depends upon. The dependency module generates a topology of the test environment that indicates the relationship of the dependencies to the primary function. A provisioning module provisions a plurality of pools based on the topology. An enterprise service bus (ESB) routing module updates ESB routing of the primary function to route to the plurality of pools in the test environment. A credentials module provides credentials of the pools in the test environment.
