What Is the Purpose of Post-Quantum Cryptography?
Purpose of Post-Quantum Cryptography The purpose of post-quantum cryptography is to secure digital communications and data against the potential threats posed by quantum computers. These powerful machines have the potential to break widely used cryptographic algorithms, such as RSA and ECC, which form the foundation of current internet security. In essence, post-quantum cryptography (PQC) seeks to future-proof digital systems against the quantum computing revolution. As quantum computing technology evolves, it becomes increasingly crucial to develop and implement cryptographic systems that can withstand quantum attacks. Without a proactive shift to quantum-resistant algorithms, sensitive data could become vulnerable, including financial transactions, healthcare information, government records, and corporate secrets. Why Quantum Computers Threaten Current Cryptography To understand the purpose of post-quantum cryptography, it helps to first explore why quantum computers are a thre...
