Notes
A Communication Channel is said to be digital if it uses a digital means to exchange (digital) messages between two digital actors.
A Communication Channel is said to be secure if it provides the following guarantees:
- every of its endpoint is being used by precisely one actor;
- during its entire lifetime, each endpoint will only be used by this actor (endpoint authentication; note that identification of the actor that uses an endpoint, or its principal is NOT required);
- only the actors that use an endpoint are capable of transmitting and reading messages through that channel (message secrecy - typically obtained by encrypting the messages);
- the receiver of a message can determine whether or not the message has been received as it was transmitted (message integrity).
