Entanglement-Based QKD: How E91 and BBM92 Actually Work
E91 and BBM92 both distribute entangled photon pairs, but they verify security in completely different ways. That difference decides what you have to trust.
BB84 Explained: How Quantum Key Distribution Actually Works
Bennett and Brassard's 1984 protocol turns key distribution into a physics problem. Here is the mechanism, the eavesdropper maths, and the four things BB84…
Finding the Assets Before You Find the Cryptography
Most cryptographic inventories stall at the asset layer, not the crypto layer. A sequencing guide for engineers working across mixed IT and OT estates.
