New post-quantum crypto

Without cryptography, the internet privacy that we all rely on for transmitting virtually all forms of digital communication would be insecure from attackers. Our current encryption methods are threatened by the breakthrough in quantum computing. Unless proactive steps are taken to mitigate this threat, large-scale quantum computers will tear down the backbone of the internet, secure communications. The majority of crypto-systems rely on asymmetric cryptography public-private keys and symmetric cryptography public-public key. Both types of cryptography require the sender of information to encrypt the data with a public key.

Post-Quantum Cryptography: A Look At How To Withstand Quantum Computer Cyber Attacks


A quantum computer is a new kind of computing device highly superior to classical computers for specific tasks. Unfortunately, breaking cryptography is one of them. With the rapidly ongoing research in quantum computing, the need for post-quantum security is emerging.

In a world where quantum computing is no longer a mere theory but becoming a reality, the danger of quantum attacks on classical cryptographic mechanisms needs to be taken into account , to ensure a future-proof protection of information assets. This necessity will soon lead to a significant market for post-quantum secure products. Product manufacturers, irrespective of whether they develop a small post-quantum crypto co-processor or a full-fledged, post-quantum security gateway, need to get ready now.

With first PQC algorithms already standardized and more to follow, the good news is that developers can start now. Post-Quantum Cryptography PQC is cryptography running on classical computers , which is secure against quantum computer attacks and classical attacks alike. Thus, no quantum computer is required to develop, implement or use PQC.

There is no time to waste — sufficiently powerful quantum computers will become a reality rather sooner than later and the world needs to be ready by then. All confidential information today, which is transmitted via the Internet or stored in the Cloud, is in danger of being revealed in the future. Compliance with legislation might require a fast transition. Together with the requirement to take the state of the art into account, this leads to the conclusion that PQC must be considered for the protection of personal data.

There are several well-studied post-quantum algorithms available. Standardization for these algorithms is ongoing and first recommendations are already published. Even if no use-case specific recommendation is yet available, hybrid schemes can help to accelerate the transition: By using a combination of a pre-quantum algorithm and a post-quantum algorithm, companies can implement the new algorithms without adding any additional risks.

Cryptographic security does not merely require a secure algorithm design but a secure implementation is equally important. History shows a variety of attacks on implementations of cryptographic algorithms, with side-channel attacks and fault-injection attacks being most difficult to mitigate.

The experience with classical cryptography implementations will help to also securely implement PQC.

Challenges and Business Opportunities of Post Quantum Cryptography

Source: ComputerWorld. Though, do these advances only have negative effects, or can this new type of computer equally be used to develop new encryption methods that will also be secure in the future? Because one thing is certain, private and sensitive data must be protected even in a future where the use of quantum computers becomes commonplace. This is precisely the topic that so-called quantum cryptography is concerned with. Here, an attempt is made to develop an encryption system that cannot be cracked without the sender or recipient of a message noticing.

The threat potential of quantum computing to society should not be underestimated. NXP is leading the way towards new public-key standards.

The Battle For Post-Quantum Security Will Be Won By Agility

In research labs around the world, a race is playing out between engineers building a completely new kind of computer and the cryptographers creating encryption tools to protect us from the superior computing power. Fully scaled quantum computers, which will rip up the computing rulebook, are still some way off: some experts say it will be another 10 years before we see at-scale, error-free quantum computers, while more conservative estimates put this figure closer to A normal bit is 1 or 0, on or off: a qubit is much more complicated. When it is measured it will be either 1 or 0; before that, it exists in a quantum superposition of those two states. Another way of visualising this is that normal bits are like coins lying on a table. They are either heads or tails up: they can be flipped over. A qubit, however, is like a coin spinning in the air. It can interact with other spinning coins, affecting how they spin, but none of them are heads or tails up until the quantum operations are complete. Thus we know many of the things that QC could achieve.


Post-Quantum Cryptography: IT Security in the Era of Quantum Technology

The development of large-scale universal quantum computers would render virtually all of today's public-key cryptography insecure. That's because the underlying mathematical problems i. So far, a quantum computer that can run Shor's algorithm to break public-key cryptography with currently used key lengths does not exist. However, in the recent years, significant progress has been made at least with respect to the relevant basic research.

Quantum Cryptography vs Post-Quantum Cryptography

Startup Europe. Grown up reporting. Monday 30 August The world may be focused on the race to vaccinate — but some necessary sprints should not make us forget about long-term marathons, including post-quantum cryptography PQC. A functioning quantum computer will make all current tools for confidential, secure data and communications — also known as cryptography — obsolete.


Post-quantum Cryptography

Y2Q is approaching — and fast! When Y2Q becomes reality, quantum computers will easily break the outdated cryptographic protocols we currently rely on to protect our systems and data. Currently, the best way to ward off a possible future quantum attack is to develop stronger quantum-resistant encryption aka post-quantum cryptography or PQC. But the truth is, most PQC methods work well only in the lab. In unpredictable real-world environments, they just cannot stand up to scrutiny. Here are the 3 drawbacks of PQC-based systems we need to be aware of. It may even render some parts of the system obsolete, raising the need for replacement hardware and adding to transition complexity. As system complexity increases, it will also increase costs and lengthen timelines.

Our current encryption methods are threatened by the breakthrough in quantum computing. Unless proactive steps are taken to mitigate this threat.

State, Local Govt Can Prepare Now for Post-Quantum Security

Quantum computers are based on the principles of quantum mechanics without being bound by the limits of circuits and electricity, so they can efficiently solve highly complex mathematical problems. Soon, quantum computers will be able to do things that were difficult to achieve with conventional computers. It is expected to play an active role in various fields such as machine learning, security, fraud detection, transaction optimization, new drug research, and space development. Quantum computers will permanently change the security aspect of the Internet.

The views expressed here are solely from the Cyber Centre. While large quantum computers do not yet exist, many researchers believe they could become a reality in the coming decades. This has spurred a significant research effort into PQC which is cryptography that would remain secure even in a world with large quantum computers. The deadline for initial submissions to the standardization process was November , and in December of that year NIST announced that there were 69 valid submissions. This marked the start of the first round of evaluation. In January the field was cut to 26 candidates for the second round, and in July the third round officially began.

What does it really mean to data protection? Is it really the end of encryption as we know it?

With quantum computing looming on the horizon , Cloudflare says it has been trialing the KEMTLS protocol and plans to use post-quantum cryptography for most internal services by the end of this year. The Transport Layer Security TLS protocol, which currently secures most internet connections, consists of a key exchange authenticated by digital signatures used to encrypt data at transport. But, says Cloudflare , with the advent of quantum computing, TLS in its current form will be broken. While various new post-quantum cryptography algorithms have been proposed, their parameters are too large to be used for establishing efficient connections on the web.
