GCHQ on Quantum Key Distribution
Schneier on Security 2018-08-01
Summary:
The UK's GCHQ delivers a brutally blunt assessment of quantum key distribution: QKD protocols address only the problem of agreeing keys for encrypting data. Ubiquitous on-demand modern services (such as verifying identities and data integrity, establishing network sessions, providing access control, and automatic software updates) rely more on authentication and integrity mechanisms -- such as digital signatures -- than on...
