iSACA Cybersecurity Fundamentals Certification Practice Exam

What is Quantum Cryptography primarily designed to address?

1. Enhancing the computational power of encryption

2. Solving key generation and secure distribution issues

3. Reducing costs related to key management

4. Improving the speed of symmetric encryption

The correct answer is: Solving key generation and secure distribution issues

Quantum cryptography is primarily designed to address the issues related to key generation and secure distribution. At the core of quantum cryptography is the concept of using quantum mechanics to ensure that any attempt to eavesdrop on the key exchange process can be detected. This is achieved through principles like quantum superposition and entanglement, which allow two parties to generate a shared, secret key with a level of security that is theoretically unbreakable given perfect conditions. The process of quantum key distribution (QKD) allows for the secure distribution of cryptographic keys between parties, ensuring that any interception or tampering can be identified. This unique approach addresses the challenges that classical cryptographic methods face, especially as computational power increases and traditional encryption can potentially be compromised by advancements in technology. Hence, the focus on solving key generation and secure distribution issues makes this option the most relevant in the context of quantum cryptography.
