Description

Strategic Intelligence: Post-Quantum Cryptography

Summary

The biggest cyber risk in the future will be from quantum computers. Quantum computers undermine the basis of the existing cryptography landscape. This risk stems from the ability of a powerful quantum computer to solve mathematical problems far faster than classical computers, thereby enabling it to break public-key encryption.

Key Highlights
  • Quantum computers will soon be able to hack digital infrastructure. Q-Day is the future date when cryptographically-relevant quantum computers (CRQCs) will be able to break public-key encryption. Even the latest asymmetric public-key encryption technologies are at risk from CRQCs. Bad actors are already harvesting encrypted data for future decryption, threatening the security of corporations and governments.
  • Post-quantum cryptography (PQC) standards will help secure online data in the future. The US National Institute of Standards and Technology (NIST) has approved three PQC algorithms, with a fourth under review. The standards together establish a global baseline for quantum-safe cryptography, enabling companies to secure their online data against hacks by quantum computers.
Scope
  • This report highlights how quantum computers threaten today's digital infrastructure by undermining the basis of the existing cryptography landscape.
  • It examines how post-quantum cryptography has become a strategic imperative and provides recommendations for both enterprises and investors.
  • It looks at the impact of quantum key distribution on security and outlines a vision for the quantum internet, which could deliver quantum-safe, secure communications at scale.
Reasons to Buy
  • Quantum computers could threaten many online assets. The cybersecurity risks span everything from encryption and authentication to national security. In other words, each key layer of digital security built on public-key cryptography must be updated to remain secure in the quantum era. Banks, personal data, and government databases are all at risk. This report gives a clear and easy-to-understand overview of this highly disruptive theme.

How Do Licenses Work?

How Do Licenses Work?

The primary function of a report license is to define how many people within a company are authorized to use the purchased report. This is separate to how a report might be delivered. Unless specifically identified otherwise, the purchase option is Single User. Below is a helpful description of that license, along with a sampling of others most commonly offered.

  • This license allows only one user to have access to and to use/read the report. It is not one user at a time or one user group; it is an individual who will be reading and utilizing the report.

  • This license allows for the entire purchasing company to read and use the report. This is the license level that would allow for a report to be placed on an internal company shared drive for access by all employees of that direct company. This license does not extend to parent or sister company use.

  • This license is designed to allow an entire department within a company full access to a report. The departmental license is a great option for companies that have more than one location and the department is spread out all over the country/world

  • This license is for companies that have one location where they want the report to be accessible by all employees within that physical location.

  • This is the most flexible of the licensing options. Some publishers will allow you to get a license for a preset number of people (typically 5). These licenses are ideal for small work groups.

License options are at the discretion of each publisher. As such, not all licenses indicated above are available for every product. If you are uncertain of the best license for your needs or would like a license that is not proactively available, please contact us and we will be happy to assist.
