Security News > 2022 > July > Q-Day: The problem with legacy public key encryption

Why legacy public key cryptography is exposing data to risk.

In public key encryption, two parties that wish to share a secret need to exchange pairs of keys.

Using the public key in conjunction with the private key, each entity can either encrypt or decrypt the secret.

Other estimates measure the time to execute brute force attacks on today's public key encryption in decades.

What will this mean for cryptography? The best estimates available today predict that quantum computers will be able to crack public key encryption in a matter of hours using what is known as Shor's algorithm.

The updgrade to PQC from legacy public key cryptography should start right away.
