Exascale isn’t the only international computing race currently underway. Around the world national interests are also scrambling to build quantum computers capable of making and breaking amazingly-complex codes. Take China for example. Already home to the most powerful supercomputer in the world, Tianhe-2, researchers in China have set their sites on the holy grail of Read more…
Documents made public by former intelligence analyst Edward Snowden reveal that the National Security Agency (NSA) has thwarted or circumvented many of the privacy safeguards of the Internet as part of a highly classified program codenamed Bullrun…

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/GPU_cluster_for_password_cracking_2012_200x.jpg” alt=”” width=”101″ height=”77″ />Today’s notion of safe passwords may soon be a thing of the past. Thanks to cheaper hardware, cloud software, and free password cracking programs, it’s easier than ever to hack these digital keys. Just how easy? Earlier this week, a custom-built GPU cluster tore through 348 billion password hashes per second during the Passwords^12 Conference in Oslo, Norway.
Blind quantum computing protocol preserves the privacy of user data in the cloud.
Members of the Microsoft Research Cryptography Group describe the complexities of building a secure cloud storage service on top of a public cloud infrastructure, which is often not fully trusted by the user. Dr. Kamara and Dr. Lauter also shed light on key architectures that combine recent and non-standard cryptographic primitives and survey the benefits such rchitectures would provide to both cloud providers and their end users.
Despite numerous advances, practical quantum computing still five decades out.
The civil engineer Konrad Zuse was born in Berlin exactly 100 years ago. In 1941, he built the world’s first computer. And thanks to his pioneering work, the scientists at the Jülich Supercomputing Center have now succeeded in setting a world record by simulating the largest quantum computer system with 42 qubits.
