Why Apple added protection against quantum computing when quantum computing doesn’t even exist yet

Apple released a new update for nearly all its devices that provides an all-new type of encryption for its iMessages to the point that, in theory, iMessages are now protected against attacks from quantum computers. This is a little tricky because, as weve covered before, quantum computers dont...

Quantum Computing Skeptics

Interesting article. I am also skeptical that we are going to see useful quantum computers anytime soon. Since at least 2019, I have been saying that this is hard. And that we dont know if its "land a person on the surface of the moon" hard, or "land a person on the surface of the sun" hard. They...

Starting your journey to become quantum-safe

There’s no doubt we are living through a time of rapid technological change. Advances in ubiquitous computing and ambient intelligence transform nearly every aspect of work and life. As the world moves forward with new advancements and distributed technologies, so too does the need to understand...

Post-Quantum Cryptography: Finally Real in Consumer Apps?

Most people are barely thinking about basic cybersecurity, let alone post-quantum cryptography. But the impact of a post-quantum world is coming for them regardless of whether or not it's keeping them up tonight. Today, many rely on encryption in their daily lives to protect their fundamental...

Breaking RSA with a Quantum Computer

A group of Chinese researchers have just published a paper claiming that they can--although they have not yet done so--break 2048-bit RSA. This is something to take seriously. It might not be correct, but its not obviously wrong. We have long known from Shors algorithm that factoring with a quant...

How can we Prevent an Internet of Compromised Things?

The shape of things to come An increasing array of physical household and business objects now come with a plethora of sensors, software, and processing abilities, connecting to like-minded devices and swapping data with additional systems via the internet or across networks. These objects and...

Gain valuable insight into the emerging world of post-quantum computing. Understand the threats attackers with access to quantum computers pose. Learn how harnessing the power of cloud security posture management CSPM can mitigate these looming dangers...

What is Quantum Computing, and Why Should Security Professionals Care?

Quantum computing basics Quantum computing embraces the laws of quantum mechanics to solve those problems that are currently too challenging for even the most high-performance modern computers. Across the board, it is a fundamental shift in computing with the potential to alter the way business i...

NIST’s Post-Quantum Cryptography Standards

Quantum computing is a completely new paradigm for computers. A quantum computer uses quantum properties such as superposition, which allows a qubit a quantum bit to be neither 0 nor 1, but something much more complicated. In theory, such a computer can solve problems too complex for conventional...

A New Attack Easily Knocked Out a Potential Encryption Algorithm

SIKE was a contender for post-quantum-computing encryption. It took researchers an hour and a single PC to break it...

Prepare for a New Cryptographic Standard to Protect Against Future Quantum-Based Threats

The National Institute of Standards and Technology NIST has announced that a new post-quantum cryptographic standard will replace current public-key cryptography, which is vulnerable to quantum-based attacks. Note: the term “post-quantum cryptography” is often referred to as “quantum-resistant...

Is quantum teleportation the future of secure communications?

“Beam me up Scotty” will always remain my first association with teleportation. And as it stands now, we are still a long way from teleporting matter, but the teleportation of information has recently made a huge step forward. Researchers in Delft say they have succeeded in teleporting quantum...

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...

Interview with the Head of the NSA’s Research Directorate

MIT Technology Review published an interview with Gil Herrera, the new head of the NSAs Research Directorate. Theres a lot of talk about quantum computing, monitoring 5G networks, and the problems of big data: The math department, often in conjunction with the computer science department, helps...

How Quantum Computers Can Impact Security

While it might be too early to completely overhaul security protocols to prepare for quantum computing — not to mention that there is currently no post-quantum cryptographic standard existing at the moment — it would be a good idea for organizations to start planning for the future...

Chinese Breakthrough in Quantum Computing a Warning for Security Teams

China’s top quantum-computer researchers have reported that they have achieved quantum supremacy, i.e., the ability to perform tasks a traditional supercomputer cannot. And while it’s a thrilling development, the inevitable rise of quantum computing means security teams are one step closer to...

Factoring 2048-bit Numbers Using 20 Million Qubits

This theoretical paper shows how to factor 2048-bit RSA moduli with a 20-million qubit quantum computer in eight hours. It's interesting work, but I don't want overstate the risk. We know from Shor's Algorithm that both factoring and discrete logs are easy to solve on a large, working quantum...

Presidential Candidate Andrew Yang Has Quantum Encryption Policy

At least one presidential candidate has a policy about quantum computing and encryption. It has two basic planks. One: fund quantum-resistant encryption standards. Note: NIST is already doing this. Two, fund quantum computing. Unlike many far more pressing computer security problems, the market...

Quantum Computing and Cryptography

Quantum computing is a new way of computing -- one that could allow humankind to perform computations that are simply impossible using today's computing technologies. It allows for very fast searching, something that would break some of the encryption algorithms we use today. And it allows us to...
