Quantum attacks on ECC

Definition

Quantum attacks on elliptic curve cryptography (ECC) refer to the potential vulnerabilities that ECC may face due to the advent of quantum computing. As quantum computers evolve, they possess capabilities that can break traditional encryption methods, including those based on the discrete logarithm problem, which ECC relies on. The implications of these attacks raise concerns about the security and longevity of ECC in a post-quantum world, prompting researchers to explore quantum-resistant alternatives.
