Entropy as a Service: Unlocking Cryptography's Full Potential

Entropy-as-a-Service: Unlocking the Full Potential of Cryptography

Securing the Internet requires strong cryptography, which depends on the availability of good entropy for generating unpredictable keys and accurate clocks. Attacks abusing weak keys or old inputs portend challenges for the Internet. EaaS is a novel architecture providing entropy and timestamps from a decentralized root of trust, scaling gracefully across diverse geopolitical locales and remain...

Towards Unlocking the Full Potential of Multileaf Collimators

A central problem in the delivery of intensity-modulated radiation therapy (IMRT) using a multileaf collimator (MLC) relies on finding a series of leaves configurations that can be shaped with the MLC to properly deliver a given treatment. In this paper, we analyse, from an algorithmic point of view, the power of using dual-layer MLCs and Rotating Collimators for this purpose. 1 Radiation thera...

Unlocking the Full Potential of the Cray XK7 Accelerator

The Cray XK7 includes NVIDIA GPUs for acceleration of computing workloads, but the standard XK7 system software inhibits the GPUs from accelerating OpenGL and related graphics-specific functions. We have changed the operating mode of the XK7 GPU firmware, developed a custom X11 stack, and worked with Cray to acquire an alternate driver package from NVIDIA in order to allow users to render and p...

Unlocking diamond's potential as an electronic material.

In this paper, we review the suitability of diamond as a semiconductor material for high-performance electronic applications. The current status of the manufacture of synthetic diamond is reviewed and assessed. In particular, we consider the quality of intrinsic material now available and the challenges in making doped structures suitable for practical devices. Two practical applications are co...
