CRISC Exam 2025 – 400 Free Practice Questions to Pass the Test

Quantum Cryptography is fundamentally rooted in the principles of quantum mechanics, a field of physics that focuses on the behavior of matter and energy at the smallest scales. This technology exploits quantum phenomena, such as superposition and entanglement, to create communication systems that are theoretically secure against eavesdropping.

Quantum key distribution (QKD), a primary application of quantum cryptography, enables two parties to generate a shared secret key while ensuring that any attempt at interception can be detected. This security feature is a direct consequence of the properties of quantum mechanics, distinguishing it from classical cryptography, which relies on computational difficulties rather than physical laws.

The other options do not accurately capture the essence of quantum cryptography. Classical mechanics is not the framework it operates within; it does not solely depend on mathematical problems, nor does it primarily utilize digital signatures, which are more aligned with conventional cryptographic methods. The unique attributes of quantum mechanics are what make quantum cryptography a significant advancement in secure communication technology.
