Can we integrate post-quantum algorithms into existing protocols? Can new protocols be designed around post-quantum systems? What is the role of double encryption and double signature? What changes do new post-quantum algorithms bring to existing protocols? A report published today seeks to answer these questions.
Quantum-resistant Post-quantum Cryptographic Solutions For Digital Forensics
The transition to post-quantum cryptography (PQC) does not end with the selection and standardization of post-quantum algorithms. Integration with existing systems and protocols is also required. The report focuses on the need for future proofing and knowledge acquisition, not limited to external standards.
Why We Need Quantum Resistant Cryptography Now
This report expands on the initial aspects of post-quantum cryptographic challenges addressed in last year’s paper: Post-Quantum Cryptography: Current Status and Quantum Mitigation.
Scientists generally agree that quantum computers, when they are built, will be able to crack widely used public-key cryptographic schemes. Because in reality, systems using the new technology do not yet exist on a large scale.
The transition to a new quantum-resistant cryptographic algorithm is expected to take several years due to complex processes and financial costs. That is why we must keep reckoning with it and be prepared to face all possible consequences.

This report addresses the difficult questions posed by post-quantum cryptography to overcome the challenges of today’s public-key cryptosystems, e-commerce, digital signatures, electronic identities, and more. The threat would be serious, although this may prove impossible for many systems with limited access, such as satellites, when introducing new cryptographic systems.
If quantum technology is explored, it can provide effective solutions to today’s technological challenges. Unfortunately, however, this new technology also brings new threats to the security of our devices and systems, as quantum computing renders most currently used cryptographic solutions vulnerable and ultimately radically changes the existing threat model. Therefore, we must adapt quickly before this happens to avoid threats to our infrastructure.
The work program envisages activities that support the creation of knowledge of cryptographic algorithms. The Agency works with expert groups to address emerging challenges and promote best practices in cooperation with the European Commission, Member States and other EU institutions.

As the cryptographic capabilities of quantum computing are likely to introduce new emerging risks, the move to quantum-secure cryptography is a countermeasure. Activities in this area are aimed at promoting the EU’s strategic digital autonomy. Lock (lock a locked lock) or https:// means you are securely connected to the .gov website. Only share sensitive information on official, secure websites.
The first four algorithms announced for post-quantum cryptography are based on structured lattices and hash functions, two families of mathematical problems that can withstand quantum computer attack.
Gaithersburg, Md. — U.S. The Commerce Department’s National Institute of Standards and Technology () has selected the first batch of encryption tools designed to withstand future quantum computer attacks that could potentially crack the security used to protect privacy. The digital systems we rely on every day. – such as online banking and email software. Four selected encryption algorithms will form part of the post-quantum cryptographic standard, expected to be finalized within two years.

“Today’s announcement is an important step forward in protecting our sensitive data from future cyber attacks by quantum computers,” said Commerce Secretary Gina M. Raimondo said. “With his expertise and commitment to cutting-edge technology, we can take the necessary steps to secure electronic information so that US businesses can continue to innovate while maintaining the trust of their customers.”
The announcement follows a six-year effort he led in 2016 that asked the world’s cryptographers to develop and then test encryption methods capable of withstanding attacks on future quantum computers that are more powerful than the relatively limited machines currently available. The selection marks the beginning of the final round of the agency’s post-quantum cryptographic standardization project.
“He continues to look to the future to anticipate the needs of US industry and society as a whole, and when they are built, quantum computers powerful enough to break current encryption pose a serious threat to our information systems,” the US deputy secretary said. State Trading Standards and Technology and Director Lori E. locatio. “Our post-quantum cryptography program has used cryptography – worldwide – to create the first set of quantum-resistant algorithms that will become a standard and significantly increase the security of our digital information.”

Four more algorithms are being considered for implementation and the finalists for the round are planned to be announced in the future. It announces its selections in two phases, requiring a wide range of defense tools. As cryptographers have recognized from the beginning, different systems and functions use encryption, and a useful standard will offer solutions designed for different situations, use different approaches to encryption, and offer more than one algorithm for each use. If someone appears to be vulnerable.

Encryption uses mathematical methods to protect sensitive electronic information, including the secure websites we browse and the e-mails we send. Widely used public key encryption systems, which rely on mathematical problems that even fast conventional computers find difficult, ensure that these websites and messages are not accessible to unwanted third parties.

However, a sufficiently powerful quantum computer, which would be based on a different technology than today’s conventional computers, could quickly solve these mathematical problems, defeating encryption systems. To counter this threat, four quantum-resistant algorithms rely on mathematical problems from both traditional and quantum computers, protecting privacy now and in the future.
Algorithms are designed for the two main functions that encryption is typically used for: general encryption, which is used to protect information exchanged over public networks; And digital signatures are used for identity authentication. All four algorithms have been developed by experts from many countries and institutions.
For the general encryption we use when accessing secure websites, you have selected the CRYSTALS-Kyber algorithm. Its advantages include relatively small encryption keys that can be easily exchanged between two parties, as well as operational speed.

For digital signatures, which we use when needed to prove identity in digital transactions or sign a document remotely, he chose three algorithms: CRYSTALS-Dilithium, FALCON and SPHINCS+ (see “Sphincs plus”). Reviewers note the high performance of the first two and recommend CRYSTALS-Dilithium as the primary algorithm, with FALCON for applications requiring smaller signatures than Dilithium can provide. The third, SPHINCS+, is slightly larger and slower than the other two, but it’s valuable as a backup for one main reason: it’s based on a different mathematical approach than the other three options.
Three of the selected algorithms are based on a family of mathematical problems called structured grids, while SPHINCS+ uses hash functions. The other four algorithms still under consideration are designed for general encryption and do not use structured lattices or hash functions in their approaches.
As the standard evolves, he encourages security experts to explore new algorithms and consider how their applications will use them, but not yet incorporate them into their systems, as the algorithms may change slightly before the standard is finalized.
Quantum Key Distribution Versus Post Quantum Cryptography
To prepare, users can list their systems for applications using public-key cryptography that will need to be replaced before cryptographically relevant quantum computers emerge. They can also alert their IT departments and suppliers about the upcoming change. If you are interested in contributing to the development of a guide for the transition to post-quantum cryptography, see the National Cybersecurity Center of Excellence’s project page. Quantum computing accelerates the computation of certain types of algorithms and provides the ability to solve some of the world’s toughest problems—medical treatment, materials science, chemical engineering, pharmacology, and more. However, this huge opportunity comes with an asterisk that cannot be ignored. Quantum computers will be able to crack the encryption currently used in our worldwide digital infrastructure for secure digital interactions with everything from e-commerce to national security.
Both symmetric and public key encryption are widely used in our digital world. Symmetric key encryption, which uses a single key for encryption and decryption, is commonly used to keep data confidential. Public key encryption uses a public key for encryption
Although quantum computers may not be available for years or even decades, the threat to our current digital ecosystem requires immediate action for the following reasons:
