What distinguishes quantum-safe from quantum-secure?

Quantum-safe cryptographic systems are deemed resistant to both classical and quantum computer attacks based on current mathematical and algorithmic knowledge. However, “resistant” implies that while there are no known methods to break these systems now, future discoveries might reveal vulnerabilities. On the other hand, quantum-secure solutions employ techniques, such as the one-time pad (OTP) encryption method with keys generated using true random numbers derived from quantum sources, designed to be computationally secure against any form of computational attack, including those using quantum computers. Thus, quantum- secure solutions promise enduring security, especially vital for safeguarding critical and long- term data against the anticipated advancements in quantum technology.
