PART 1Executive Overview
1Definition

Post-Quantum Cryptography (PQC) refers to cryptographic systems that are designed to be secure against both classical and quantum computers. These protocols aim to replace current public-key cryptography algorithms which could become vulnerable to attacks by quantum computers.

2Problem It Solves

PQC addresses the security threat posed by future quantum computers, which could break many current cryptographic systems based on factoring large integers or discrete logarithms.

PART 2Technical & Manufacturing
4How It Works

PQC employs advanced mathematical problems, such as lattice-based cryptography, code-based cryptography, multivariate polynomial cryptography, hash-based signatures, and isogeny-based cryptography, to create secure encryption methods that are resistant to both classical and quantum computing threats. These algorithms leverage the computational complexity of these problems which are believed to be intractable for quantum computers.

5Materials Used
6Manufacturing / Creation Process

The manufacturing process involves developing and testing new algorithms that can resist attacks from both classical and quantum computers. This includes rigorous mathematical analysis to ensure the robustness of the protocols against various types of attacks.

7Build Process

The build process for PQC involves extensive computational modeling, simulation, and testing on classical computers before deployment. It also requires collaboration between mathematicians, computer scientists, and cryptographers to develop and validate new cryptographic schemes.

8Energy Requirements

Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking. Overall, the operational power requirements are moderate compared to quantum computing but can be higher during development stages.
