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.
