Final answer:
If large-scale quantum computing becomes feasible, it could significantly impact InfoSec in terms of breaking current encryption algorithms, compromising the privacy of sensitive data, but also enabling the development of quantum-resistant encryption methods.
Step-by-step explanation:
If large-scale quantum computing becomes feasible, it could significantly impact InfoSec (information security) in several ways. One major impact could be on encryption algorithms. Quantum computers have the potential to break current encryption algorithms that rely on the difficulty of factoring large numbers. They can easily solve complex mathematical problems that classical computers would take an impractically long time to solve.
Another impact could be on the privacy of sensitive data. Quantum computers could potentially break the cryptographic protocols used to protect data during transmission, making it easier for hackers to intercept and read information.
Additionally, large-scale quantum computing could also potentially enable quantum-resistant encryption algorithms. Scientists are already working on developing new encryption methods that would be resistant to attacks from quantum computers.
