Good encryption is not vulnerable to a known-plaintext attack, but that's no reason for #NATO to yolo here. They used a plaintext that's fully knowable by an adversary with a good antenna, a clock and some knowledge of the pilot schedule. If said adversary kept these recordings for a decade, now it's party time. Let's just hope nobody used this particular cipher mode. https://image.nostr.build/c85f0ae8a7d57327fc5c53f87497ea4e083e9dd8277290e5e82201d39d16cb2c.png #38c3 https://media.ccc.de/v/38c3-breaking-nato-radio-encryption
The Noise framework fixes this by generating ephemeral keys during the handshake. http://www.noiseprotocol.org
