Existing encryption systems are designed to protect secret keys or other data under a "black box attack," where the attacker may examine the algorithm, and various inputs and outputs, but has no visibility into the execution of the algotitm itself. However, it has been shown that the black box model is generally unrealistic, and that attack efficiency rises dramatically if the attacker can observe even minor aspects of the algorithm's execution. The invention protects software from a "white-box attack", where the attacker has total visibility into software implementation and execution. In general, this is done by encoding the software and widely diffusing sites of information transfer and/or combination and/or loss. Other embodiments of the invention include: the introduction of lossy subcomponents, processing inputs and outputs with random cryptographic functions, and representing algorithmic steps or components as tables, which permits encoding to be represented with arbitrary nonlinear bijections.

An ST-MRAM structure, a method for fabricating the ST-MRAM structure and a method for operating an ST-MRAM device that results from the ST-MRAM structure each utilize a spin Hall effect base layer that contacts a magnetic free layer and effects a magnetic moment switching within the magnetic free layer as a result of a lateral switching current within the spin Hall effect base layer. This resulting ST-MRAM device uses an independent sense current and sense voltage through a magnetoresistive stack that includes a pinned layer, a non-magnetic spacer layer and the magnetic free layer which contacts the spin Hall effect base layer. Desirable non-magnetic conductor materials for the spin Hall effect base layer include certain types of tantalum materials and tungsten materials that have a spin diffusion length no greater than about five times the thickness of the spin Hall effect base layer and a spin Hall angle at least about 0.05.

Some embodiments provide a novel method for deploying different virtual networks over several public cloud datacenters for different entities. For each entity, the method (1) identifies a set of public cloud datacenters of one or more public cloud providers to connect a set of machines of the entity, (2) deploys managed forwarding nodes (MFNs) for the entity in the identified set of public cloud datacenters, and then (3) configures the MFNs to implement a virtual network that connects the entity's set of machines across its identified set of public cloud datacenters. In some embodiments, the method identifies the set of public cloud datacenters for an entity by receiving input from the entity's network administrator. In some embodiments, this input specifies the public cloud providers to use and/or the public cloud regions in which the virtual network should be defined. Conjunctively, or alternatively, this input in some embodiments specifies actual public cloud datacenters to use.

A single main steel wheel rides on a single main steel rail of a guideway to support and drive a carrier and to facilitate steering and provide a simplified, more compact and less costly construction. The carrier can support a car through a platform having elements and chocks for locking contact with a front bumper and front wheels of the car Auxiliary wheels and rails cooperate to cause nearly all weight to be carried through the single main wheel. Traction is increased when necessary through application of increased upward forces to undersides of auxiliary rails and/or through developing magnetic forces between the steel wheel and steel rail. An AC induction motor is a main source of drive power. Acceleration and braking are assisted through epicyclic gearing, braking means and a DC motor/generator that is connected to a battery and that drives the carrier if supply of AC fails.

TOF system optical power is augmented using auxiliary optical emitter unit(s) that may be a wireless (WOE), or a plug-wired (PWOE). WOE units sense emitted TOF system optical energy S_out and emit optical energy S_out-n preferably dynamically synchronized in frequency and in phase to S_out as received by the WOE. Each WOE includes at least one optical sensor to detect S_out, and internal feedback ensuring that frequency and phase of the WOE emitted S_out-n optical energy are dynamically synchronized with frequency and phase of the TOF emitted S_out optical energy.
