Quantum-safe protocols

Definition

Quantum-safe protocols are cryptographic algorithms designed to be secure against the potential threats posed by quantum computing. These protocols use mathematical structures that remain secure even when faced with the advanced computational power of quantum computers, which could easily break many traditional encryption methods. By ensuring data protection in a future where quantum computers become prevalent, quantum-safe protocols play a crucial role in safeguarding sensitive information and maintaining trust in digital communications.

5 Must Know Facts For Your Next Test
