Post Quantum Cryptography

Most of us have little or no knowledge of how information on our web browsers is protected. Whenever you are using online services such as emails, bank accounts, or credit cards, a web protocol encrypts and saves the data. These encryption protect all types of electrical communication, including health records, passwords, and digital signatures.
Cryptography protects all information on transit or in the storage on the internet. It operates on asymmetric and symmetric logarithms. However, in recent years, there has been an increasing fear of the emergence of quantum computers that might undermine these defenses. Therefore, as a precaution, researchers and security firms have come up with Post Quantum Cryptography.

So, What Exactly Is a Post Quantum Cryptography?

Post Quantum Cryptography (PQC) refers to new measures put in place to protect data and sensitive information from future quantum computers mounted by hackers. These computers could allow hackers to access the data through algorithmic trapdoors faster, with their superposition ability. Besides, the phenomenon known as entanglement enables them to communicate with one another from a distance. Therefore, due to their processing power, quantum computers can generate and test all possible cryptographic keys within a short time.

How The PQC Works?

As an effort to stop the risks that technology poses to data storage, new kinds of encryption approaches have been implemented with the current computers. These more robust defenses will be impenetrable to future attacks. DigiCert, in collaboration with other security players, is creating new PCQ to secure database encryption.

The first defense is to increase the number of encryption keys. This move increases the size of the permutations significantly. Therefore, even with a quantum machine that uses Grover’s algorithm, it will be nearly impossible to search through. Surveys show that the quantum threat is looming, and you need to start replacing database encryption solutions and SSL certificates.

Another practical approach is creating a more complex trapdoor function. Cyber security firms are working on various strategies like super singular isogeny and lattice-based cryptography for key exchange. They are very complex that not even a powerful quantum computer with a super algorithm would easily crack it.


When quantum computers become a reality, the elliptic curves, RSA, and cryptographic measures will be of no use. However, PQC provides a secure means to protect yourself.
Using Digicert pro SSL Certificates gives you ease and convenience of having all your data and sub-domains under one binding cryptographic key. Besides, it provides for a secure connection from a web server to a browser.

Furthermore, you can stay ahead of the curve by using a secure site pro. It provides the highest level of authentication and extra features. These further give robust protection and comprehensive security against targeted attacks.

Which Digicert SSL Certificate Offers Post Quantum Cryptography?

The Digicert Secure Site Pro and Secure Site pro EV are the only SSL Certificates that provides Offers PCQ?

Final Thoughts

It takes time to develop and deploy cryptography techniques. Therefore, even though we think that we still have time to create cryptography defenses, we need to start working now to get ahead of the quantum threat. Experience the convenience on your data using Digicert SSL. Digicert provides PQC through hybrid SSL certificates, secure site pro, and CT Log monitoring.
