Abstract

In the context of the development of quantum technology, most asymmetric encryption algorithms managed to be broken using Shor's algorithm, while symmetric encryption algorithms, such as AES-256, are believed to be unbroken for the moment, Grover's algorithm has been able only to reduce AES brute force attack time to its square root. This paper proposes to present how Quantum technology can affect current security algorithms and analyze how it can be used to improve our data protection by developing new algorithms. Quantum cryptography alongside Quantum key distribution could be a deal-breaker by using new encryption algorithms and providing new solutions to different cryptographic tasks that are known to be impossible by using normal computers. In the end, it will be discussed how the concept of quantum teleportation could provide new, faster, and much more secure solutions in telecommunication compared with the ones based on radio technologies.
