Everything you need to know about the NSA hack (but were afraid to Google)

Posted by in categories: cybercrime/malcode, encryption, information science, privacy

A day in the life of an NSA Hacker.


In what Edward Snowden deems “not unprecedented,” hackers calling themselves the Shadow Brokers have collected NSA-created malware from a staging server run by the Equation Group, an internal hacking team. The Shadow Brokers published two chunks of data, one “open” chunk and another encrypted file containing the “best files” that they will sell for at least $1 million. Wikileaks has said they already own the “auction” files and will publish them in “due course.”

They’ve also released images of the file tree containing a script kiddie-like trove of exploits ostensibly created and used by the NSA as well as a page calling out cyber warriors and “Wealthy Elites.” The page also contains links to the two files, both encrypted. You can grab them using BitTorrent here.

China launches ‘hack-proof’ quantum satellite in world first

Posted by in categories: encryption, quantum physics, security, space

This is so exciting.


The transfer of data using quantum communications is considered impenetrable due to a particle phenomenon known as quantum entanglement, with eavesdroppers unable to monitor the transfer without altering the quantum state and thereby being detected. In theory, two parties can communicate in secret by sharing an encryption key encoded in a string of photons.

China’s big-spending quantum research initiative, part of Beijing’s broader multi-billion dollar strategy to overtake the West in science and space research, is being closely watched in global scientific research and security circles, with groups from Canada, Japan, Singapore and Europe also planning their own quantum space experiments.

Quantum computing and cryptocurrencies: Are Steemit and bitcoin safe?

Posted by in categories: bitcoin, computing, cryptocurrencies, encryption, quantum physics, security

Article repeats a lot of the knowns on QC such as bit v. Qubit; and finally provides some good info on pros and cons of Bitcoin and Lamport signatures technique with QC. However, the author didn’t seem to mention any of the work that D-Wave for example is doing with Block chaining. Also, I saw no mention of the work by Oxford on the logic gate which improve both the information processing performance and the security of information transmissions.


In a classical computer bits are used that can either be 0 or 1. In a quantum computer these bits are replaced with Qubits (quantum bits). These Qubits can be 0 or 1, or both at the same time. This is caused by a phenomenon in the quantum realm called superposition. At scales the size of an atom and small molecules, the spin of particles is not determined until it is observed. A pair of Qubits can be in any quantum superposition of 4 states, and three Qubits in any superposition of 8 states. In general, a quantum computer with n Qubits can be in a superposition of up to 2^n different states simultaneously (this compares to a normal computer that can only be in one of these 2^n states at any one time). Because of this, a quantum computer is able to perform computations at the same time, while classical computers perform computations one at a time.

Researchers Made the First Quantum Enigma Machine

Posted by in categories: encryption, quantum physics

A quantum enigma machine is theoretical device that is able to use photons to encrypt messages using keys that are shorter than the message itself—and now it’s real.

New way to model molecules

Posted by in categories: biological, chemistry, computing, encryption, quantum physics, robotics/AI, solar power, sustainability

Magine a future in which hyper-efficient solar panels provide renewable sources of energy, improved water filters quickly remove toxins from drinking water, and the air is scrubbed clean of pollution and greenhouse gases. That could become a reality with the right molecules and materials.

Scientists from Harvard and Google have taken a major step toward making the search for those molecules easier, demonstrating for the first time that a quantum computer could be used to model the electron interactions in a complex molecule. The work is described in a new paper published in the journal Physical Review X by Professor Alán Aspuru-Guzik from the Department of Chemistry and Chemical Biology and several co-authors.

“There are a number of applications that a quantum computer would be useful for: cryptography, machine learning, and certain number-theory problems,” Aspuru-Guzik said. “But one that has always been mentioned, even from the first conceptions of a quantum computer, was to use it to simulate matter. In this case, we use it to simulate chemistry.”

Quantum computing is getting closer

Posted by in categories: encryption, information science, quantum physics, supercomputing

Electronic computer technology has moved from valves to transistors to progressively more complex integrated circuits and processor designs, with each change bringing higher levels of performance. Now the advent of quantum computers promises a huge step increase in processor performance to solve certain types of problems.

Quantum computers are much faster than the world’s fastest supercomputers for some applications. In 1994 Peter Shor, an applied mathematician at Bell Laboratories, gave the encryption world a shock when he demonstrated an algorithm showing that quantum computers could threaten conventional prime number based encryption methods.

If an adversary conducts successful espionage raids on encrypted information stored in present technology computer installations, possibly through a compromised or issue-motivated individual who transfers it to portable media, it could become vulnerable to decryption by that rival’s quantum computers.

Pass the hash for peace, love and security in the quantum computing age

Posted by in categories: computing, encryption, quantum physics, security

Excellent write up on a paper submitted to the International Association for Cryptologic Research, by a group of UK and Belgian researchers are offering up a dig-sig scheme to assist in the addressing of Digital signatures (one of the fundamental parts of cryptography) in a post-quantum world. Expect the heat to rise on QC security as China’s launch date nears for the new Quantum Satellite.

China’s new quantum satellite paves the way for unhackable satellite internet

Posted by in categories: cybercrime/malcode, encryption, internet, quantum physics, satellites

All that I can say is “WOW!”


CHINA is on the brink of launching a groundbreaking new satellite capable of conducting quantum experiments in space, leading some to predict it will usher in the beginning of a new space race.

The world will be watching very closely after the Chinese-led satellite launches in August. If it proves successful in carrying out the quantum experiments, China is expected to follow it with many more in a bid to create a super secure network that uses an encryption technique based on the principles of quantum communication.

Here’s How Google Is Racing to Protect You From Quantum Hackers

Posted by in categories: computing, encryption, quantum physics

This is a true question especially since China launches their new Quantum Satellite communications in the next few weeks. I do believe some will be protected; however, the broader majority will be a stretch.


The encryption of today will be broken by the computers of tomorrow, even retroactively.
