Research Directions in Quantum Computer Cybersecurity

This document presents a concise overview of the contemporary research directions in quantum computer cybersecurity. The aim of this document is not to be a survey, but rather a succinct summary of the major research directions in quantum computer cybersecurity at the end of the first half of the...

No, The Chinese Have Not Broken Modern Encryption Systems with a Quantum Computer

The headline is pretty scary: "China's Quantum Computer Scientists Crack Military-Grade Encryption." No, it's not true. This debunking saved me the trouble of writing one. It all seems to have come from this news article, which wasn't bad but was taken widely out of proportion. Cryptography is...

Signal Messenger Introduces PQXDH Quantum-Resistant Encryption

Encrypted messaging app Signal has announced an update to the Signal Protocol to add support for quantum resistance by upgrading the Extended Triple Diffie-Hellman X3DH specification to Post-Quantum Extended Diffie-Hellman PQXDH. "With this upgrade, we are adding a layer of protection against the...

Breaking 256-bit Elliptic Curve Encryption with a Quantum Computer

Researchers have calculated the quantum computer size necessary to break 256-bit elliptic curve public-key cryptography: Finally, we calculate the number of physical qubits required to break the 256-bit elliptic curve encryption of keys in the Bitcoin network within the small available time frame...

A week in security (September 23 – 29)

Last week on Labs, we highlighted an Emotet campaign using Snowden’s new book as a lure, discussed how 15,000 webcams are vulnerable to attack, how insurance data security laws skirt political turmoil, and how the new iOS exploit checkm8 allows permanent compromise of iPhones. Other cybersecurity...

Post-Quantum Algorithms

NIST has organized a competition for public-key algorithms secure against a quantum computer. It recently published all of its Round 1 submissions. Details of the NIST efforts are here. A timeline for the new algorithms is here...

Google Testing Post-Quantum Cryptography in Chrome

Plenty has been speculated since the Snowden documents were made public about the NSA’s interest in building a quantum computer that could break current encryption securing communication worldwide. Quantum computing on a practical scale is a distant goal, but some do exist that leverage some...

It Works! Google's Quantum Computer is '100 Million Times Faster' than a PC

Announcing the results of its experiment, Google says Quantum Computer is More than 100 Million times faster than a regular PC. Two years ago, Google and NASA National Aeronautics and Space Administration bought a D-Wave 2X quantum computer, which they have been experimenting at the U.S. space...

Unbreakable Encryption inspired by Human Biology

When we talk about security, only one thing cames to our mind – ENCRYPTION. Encryption of our online messages, encryption of our emails, encryption of our voice call, encryption of our every personal data and communication that we have to keep away from cybercriminals and, if I am not wrong, also...

NSA will not stop spying on us, next move Quantum computer to break strongest Encryption

--- Image Credit: The guardian If I say that NSA National Security Agency will never stop spying on us then it won’t be wrong. After the exposure of the large number of surveillance scandals including PRISM, DROPOUTJEEP, XKeyscore and many many more which are now publicly known as well as unknown...
