ย The current state of encryption is based on difficult mathematical problems that traditional computers have a hard time solving. Quantum computers, on the other hand, may use techniques like Shorโs Algorithm to crack these codes far more quickly. The data we encrypt now, like healthcare and government information, might be at risk if attackers were to intercept encrypted transmissions for eventual decoding, even if fully operational quantum computers are still decades away.

The four quantum-resistant algorithmsโCRYSTALS-Kyber, CRYSTALS-Dilithium, FALCON, and SPHINCS+โwere disclosed by the National Institute of Standards and Technology (NIST) in 2022. Data security in the quantum age is guaranteed by these algorithms, which can survive assaults from both classical and quantum realms.

Yet, before QKD can be extensively adopted, we still need to solve practical issues including distance constraints and the requirement for additional infrastructure.
ย Companies need to start incorporating algorithms that are resistant to quantum assaults and determine what data is susceptible to these attacks. To make the transition easier and more compatible, a hybrid technique is recommended, which incorporates conventional and post-quantum cryptography.
