Post-Quantum Security refers to the development of cryptographic systems that are secure against the potential threats posed by quantum computers. Traditional encryption methods, such as those based on RSA or Elliptic Curve Cryptography, could be easily broken by sufficiently powerful quantum computers, which use quantum bits or qubits to perform calculations at unprecedented speeds. To address this vulnerability, researchers are working on new algorithms that can withstand attacks from quantum computers. These algorithms are part of a broader effort to ensure that sensitive data remains protected in a future where quantum computing is more prevalent, thus maintaining the integrity of digital communications and transactions.
