What are cryptographic keys, and why should they be kept safe? A cryptographic key is a string of data that is used to encrypt data (to the data secret), decrypt data (to perform the reverse operation ...

Quantum computing is reshaping the foundation of digital security and the transition to post-quantum cryptography is no ...

This course covers the basic knowledge in understanding and using cryptography. The main focus is on definitions, theoretical foundations, and rigorous proofs of security, with some programming ...

Asymmetric vs Symmetric Encryption: What’s the Difference? Your email has been sent Both asymmetric and symmetric encryption are being used by businesses to protect ...

How does symmetric key encryption work with public-key encryption when securing a connection between browser and server? I know the Browser and server start off using asymmetric encryption then switch ...

Once quantum computers become a commercial reality, they will change the ground rules for cryptography. Here's how quantum cryptography would work, and an explanation of the benefits and pitfalls of ...

We all know the usual jokes about the ‘S’ in ‘IoT’ standing for ‘Security’. It’s hardly a secret that security in embedded, networked devices (‘IoT devices’) is all too often a last-minute task that ...

When quantum computers become powerful enough, they could theoretically crack the encryption algorithms that keep us safe. The race is on to find new ones. Tech Review Explains: Let our writers ...
