PART 2 Cryptography Fundamentals: You can’t hide what isn’t there

As previously discussed in part 1 of this series communication can exist between one or more entities without ever making their existence known even when such entities have intelligence that their communications are being monitored. This is seen at any two points where messages must fall into ‘public space’ during ransit from sender to recipient. One of the best examples the coded communication that occurs in prison systems. Where mixed in various methods are orders to get things done; contraband gotten; kill people.
