Top 3 Most Quantum-Vulnerable Encryption Methods

The transition to post-quantum cryptography is necessitated by the inherent weakness of widely used asymmetric encryption algorithms against Shor's algorithm.

The top 3

  1. RSA Cryptography: RSA relies on the difficulty of factoring large integers, a problem easily solved by a sufficiently powerful quantum computer running Shor's algorithm. RSA Cryptography
  2. Elliptic Curve Cryptography (ECC): Widely used in Bitcoin wallet addresses, ECC provides high security on classical computers but is rendered entirely insecure by quantum decryption. Elliptic Curve Cryptography
  3. Diffie-Hellman Key Exchange: This foundational method for secure data transmission is susceptible to quantum-based 'harvest now, decrypt later' attacks. Diffie-Hellman
