Synopsis

Reports remote services that do not offer post-quantum ciphers.

Description

This plugin reports network services that do not offer post-quantum ciphers. Tenable makes no attempt to determine whether the remote service would be vulnerable to a post-quantum attack.

However, cryptography that depends on the classic difficulty of solving the discrete logarithm problem or on the classic difficulty of large prime factorization is broken by Shor's algorithm. Examples of this are RSA asymmetric encryption and Diffie-Hellman key exchange.
