Performance Overhead: Encryption processes can slow down devices, especially with resource-intensive algorithms. Data Recovery Issues: Loss of encryption keys can make data permanently inaccessible.

Widely used encryption algorithms like RSA and elliptic-curve cryptography (ECC) will be pointless. Depending on who is running the quantum computers, they will turn from superhero to supervillain.

The first public key encryption algorithm: RSA The first algorithms using asymmetric keys were devised in secret by the British government's SIGINT agency, GCHQ, in 1973.

Some encryption technologies, such as hardware security modules, were available with the pre-PQC standard algorithms years ago. Now that the actual standards are out, however, it's time to upgrade ...

In today’s world, encryption is the new boundary of privacy. Encryption is the new front yard. It’s the new perimeter. It defines what digital information is private and what is public.
