An Explanation Of Post-Quantum Cryptography

In this video, Informa TechTarget senior site editor Michaela Goss explains how quantum computers threaten modern encryption standards and why post-quantum cryptography is critical for protecting data in the quantum era.
The quantum era might be nearer than you think -- and organizations need to be ready for it.
Cryptography is a centerpiece of modern cybersecurity. Cryptography scrambles sensitive data with techniques such as coded algorithms, signatures and hashes to obscure it from all -- except the intended recipients.
But cryptography has an Achilles heel -- the cryptographic math itself. You see, it takes a mathematical process to encrypt and decrypt data. The reason modern cryptography works today is that the math to reverse-engineer an encryption key is too complicated for current computing to handle.
