Quantum Ready Or Quantum Shattered. Reinventing Cybersecurity For Infinite Horizons

As quantum computing races toward practical reality, the security of current cryptographic systems is at a critical juncture. Established protocols—such as RSA and ECC—face a grave threat from quantum-capable adversaries armed with algorithms like Shor’s and Grover’s. This talk of mine explores post-quantum cryptography (PQC) as a cornerstone for future-proofing data protection in an era poised to witness multiple industrial revolutions over the next two decades.

Key discussion points that will be included are:
