Sažetak
Quantum cryptography utilizes the fundamental laws of quantum mechanics to establish secure communication channels between different entities. One such use is Quantum Key Distribution (QKD), which facilitates the creation of a confidential shared key for the purpose of encrypting and decrypting messages. The presence of quantum features such as superposition and entanglement makes eavesdropping detectable and prohibits replication of quantum states. Numerous cryptographic techniques in contemporary times rely on the challenge of factoring large numbers and calculating discrete logarithms. However, Shor's algorithm can swiftly factor numbers on a quantum computer, undermining conventional encryption methods like RSA and ECC. The QKD technique has been proposed as a solution to this issue. In the field of post-quantum cryptography, numerous potential algorithms have emerged as candidates that have the ability to withstand attacks from quantum computers. The talk will focus on the difficulties and solutions that quantum computing brings to the world of cryptography.
