About Post-Quantum Cryptography (PQC)
Post-Quantum Cryptography (PQC) aims to construct public key cryptosystems that are believed to be secure even against quantum computers. While traditional public-key cryptographic systems like RSA, ECC, and DH rely on the computational difficulty of problems like integer factorization and discrete logarithms, quantum computers that leverage Shor's algorithm can solve these problems efficiently. PQC focuses on algorithms based on mathematical problems that are resistant to quantum computing attacks, such as lattice-based cryptography, code-based cryptography, multivariate polynomial cryptography, and hash-based cryptography. PQC is crucial for securing communications in a future where quantum computers become practical.
Adversaries can now intercept and store encrypted communications with the intent to decrypt them in the future when quantum computers are capable of breaking current cryptographic systems.
The transition to quantum-safe cryptography is a proactive measure to ensure long-term confidentiality and security of your data and domain.
