Block ciphers can be easily made quantum-safe by doubling the key size (see "Grover's Algorithm"). We might have to update everyone's browser to support extending AES to 512 bits, but it's doable. The real problem is public key ciphers that rely on prime number factorization. Eliptic curves are one solution, but the only people who seem to have in-depth knowledge about them are in the NSA. |
