Thirty Years Later, a Speed Boost for Quantum Factoring

Posted by in categories: computing, information science, mathematics, quantum physics, security

As Shor looked for applications for his quantum period-finding algorithm, he rediscovered a previously known but obscure mathematical theorem: For every number, there exists a periodic function whose periods are related to the number’s prime factors. So if there’s a number you want to factor, you can compute the corresponding function and then solve the problem using period finding — “exactly what quantum computers are so good at,” Regev said.

On a classical computer, this would be an agonizingly slow way to factor a large number — slower even than trying every possible factor. But Shor’s method speeds up the process exponentially, making period finding an ideal way to construct a fast quantum factoring algorithm.

Shor’s algorithm was one of a few key early results that transformed quantum computing from an obscure subfield of theoretical computer science to the juggernaut it is today. But putting the algorithm into practice is a daunting task, because quantum computers are notoriously susceptible to errors: In addition to the qubits required to perform their computations, they need many others doing extra work to keep them from failing. A recent paper by Ekerå and the Google researcher Craig Gidney estimates that using Shor’s algorithm to factor a security-standard 2,048-bit number (about 600 digits long) would require a quantum computer with 20 million qubits. Today’s state-of-the-art machines have at most a few hundred.

AI researchers expose critical vulnerabilities within major large language models

Posted by in categories: internet, robotics/AI, security

Large Language Models (LLMs) such as ChatGPT and Bard have taken the world by storm this year, with companies investing millions to develop these AI tools, and some leading AI chatbots being valued in the billions.

These LLMs, which are increasingly used within AI chatbots, scrape the entire Internet of information to learn and to inform answers that they provide to user-specified requests, known as “prompts.”

However, computer scientists from the AI security start-up Mindgard and Lancaster University in the UK have demonstrated that chunks of these LLMs can be copied in less than a week for as little as $50, and the information gained can be used to launch targeted attacks.

High-Severity Flaws in ConnectedIO’s 3G/4G Routers Raise Concerns for IoT Security

Posted by in categories: internet, security

Multiple high-severity security vulnerabilities have been disclosed in ConnectedIO’s ER2000 edge routers and the cloud-based management platform that could be exploited by malicious actors to execute malicious code and access sensitive data.

“An attacker could have leveraged these flaws to fully compromise the cloud infrastructure, remotely execute code, and leak all customer and device information,” Claroty’s Noam Moshe said in an analysis published last week.

Vulnerabilities in 3G/4G routers could expose thousands of internal networks to severe threats, enabling bad actors to seize control, intercept traffic, and even infiltrate Extended Internet of Things (XIoT) things.

A Scanner Darkly

Posted by in categories: biotech/medical, government, security

America in the near future has lost the war against drugs. Paranoia reigns as 2 out of every 10 Americans have been hired by the government to spy on the other 8 in the name of national security and drug enforcement. Enter Fred, a reluctant undercover cop recruited by the government. To maintain his cover, Fred regularly ingests the popular Substance D. The drug has caused Fred to develop a split personality, of which he is unaware; his alter ego is Bob Arctor, a drug dealer. Fred’s superiors set up a hidden holographic camera in his home as part of a sting operation to snare Bob. A “scramble suit” that changes his appearance allows Fred to appear on camera as Bob and prevents his colleagues from knowing his true identity. The camera in Fred/Bob’s apartment reveals that Bob’s friends regularly betray one another for the chance to score more drugs.

A Day Without Space: GPS Is Ground Zero For The New Space Race

The 2 SOPS or 2nd Space Operations Squadron commander, Lt Col Robert Wray… More.


Of all the missions the Space Force performs daily for a grateful nation, there is none more ubiquitous and essential than GPS. Today’s soldiers and sailors depend on reliable, accurate, and secure GPS as much as they do any weapon they employ. Meanwhile, the rest of the world is just as dependent on GPS to enable basic mobility and underpins every other sector of the modern global economy. The criticality of secure global navigation and timing to both warfighting and the national economy makes it unique – we simply could not go a day without space. In so few words, GPS’ future is ground zero for the new space race.

The 2 SOPS or 2nd Space Operations Squadron commander, Lt Col Robert Wray reminds me that “14 of the 16 critical infrastructures designated by the Department of Homeland Security rely on 24/7 GPS to operate for the country.” But the newest GPS satellites in use today are the same school bus sized ones Gen. Hyten has lamented are, “juicy targets” for our adversaries – marvels of modern engineering, yes, but no longer sufficient to meet modern needs.

Chi-Nu experiment ends, bolsters nuclear security and energy reactors

Posted by in categories: nuclear energy, physics, security

The results of the Chi-Nu physics experiment at Los Alamos National Laboratory have contributed essential, never-before-observed data for enhancing nuclear security applications, understanding criticality safety and designing fast-neutron energy reactors. The Chi-Nu project, a years-long experiment measuring the energy spectrum of neutrons emitted from neutron-induced fission, recently concluded the most detailed and extensive uncertainty analysis of the three major actinide elements—uranium-238, uranium-235 and plutonium-239.

“Nuclear and related nuclear chain reactions were only discovered a little more than 80 years ago, and experimenters are still working to provide the full picture of fission processes for the major actinides,” said Keegan Kelly, a physicist at Los Alamos National Laboratory. “Throughout the course of this project, we have observed clear signatures of fission processes that in many cases were never observed in any previous experiment.”

The Los Alamos team’s final Chi-Nu study, on the isotope uranium-238, was recently published in Physical Review C. The experiment measured uranium-238’s prompt fission spectrum: the energy of the neutron inducing the fission—the neutron that crashes into a nucleus and splits it—and the potentially wide-ranging energy distribution (the spectrum) of the neutrons released as a result. Chi-Nu focuses on “fast-neutron-induced” fission, with incident neutron energies in millions of electron volts, where there have typically been very few measurements.
