Post-quantum cryptography is a field of research that focuses on developing cryptographic techniques that are resistant to attacks by quantum computers. Quantum computers have the potential to break many classical cryptographic algorithms currently in use, such as RSA and elliptic curve cryptography, due to their ability to factor large numbers and compute discrete logarithms efficiently.
The need for PQC arises from the fact that large-scale, practical quantum computers are expected to be built in the near future. This poses a significant threat to the security of our current cryptographic systems, which rely on the difficulty of certain mathematical problems (e.g., factorization, discrete logarithms) to ensure their security.
Key Challenges:
Quantum attacks: Quantum computers can perform certain calculations much faster than classical computers, which could potentially break many classical cryptographic algorithms.
Key exchange: Quantum computers can also potentially break key exchange protocols, such as Diffie-Hellman key exchange and RSA key exchange.
Cryptographic standards: Many cryptographic standards, such as TLS and SSL, rely on classical algorithms that may be vulnerable to quantum attacks.

In today's digital age, our identities are increasingly tied to the digital world. From passports and IDs to online profiles and financial transactions, our identities are constantly being verified and authenticated. But with the advent of quantum computing, the security of these identity verification processes is under threat.
- Secure authentication: PQC can provide secure authentication mechanisms, ensuring that identities are verified and protected from quantum attacks.
- Digital signatures: PQC can offer secure digital signature schemes, which can verify the authenticity of digital documents, such as identity documents, without being vulnerable to quantum attacks.
- Encryption:: PQC can provide secure encryption methods, ensuring that sensitive information, such as biometric data or personal identifiable information (PII), is protected from unauthorized access.
- Privacy:: PQC can help protect individuals' privacy by ensuring that their sensitive information remains confidential and secure.
- Identity verification:: PQC can be used to verify identities securely, even in the presence of quantum computers.
