Post-Quantum Cryptography (PQC): The Essential Shield for the Coming Quantum–AI Era

Post-Quantum Cryptography (PQC) is a new cryptographic technology designed to securely protect information even against attacks from powerful future quantum computers.

Most of the cryptographic systems we use today are at risk of being easily broken once quantum computers emerge. To prepare for the coming Quantum–AI era, a new cryptographic paradigm—Post-Quantum Cryptography (PQC)—is essential.
