Quantum technologies have developed rapidly in recent years, introducing risk of rendering traditional cryptographic systems vulnerable, while also offering promising solutions for strengthening data protection.In this talk, you will learn:
- What quantum technologies might be used in present cryptographic solutions
- How quantum computers will impact cryptography and data security in our digital landscape and how we can prepare for this.
Along with the idea of building quantum computers, algorithms designed for implementation on these computers were created. Some of these algorithms pose a threat to data security. An example of such an algorithm is the quantum Shor algorithm created in 1994, which allows finding the prime factors of an integer in a much shorter time than previously known classical algorithms. Shor's algorithm therefore poses a real threat to asymmetric cryptography algorithms, which are used daily in systems around the world and are resistant to attacks using classical computers. At the moment, there is no generally known quantum computer that would be advanced enough to break an algorithm such as RSA with a suitably long key, but further development of quantum computers may cause the currently commonly used public key cryptography algorithms to cease to be secure. We cannot be sure how quickly and whether quantum computers will develop to such a level that classical algorithms used today will be broken, but we should prepare for this. Therefore, new algorithms are being created, and prepared for implementation on classical computers, which are resistant to known attacks using classical and quantum computers and are an alternative to algorithms susceptible to quantum attacks. These algorithms are classified as Post Quantum Cryptography (PQC).
