The Secret Key-Private Key Capacity Region for Three Terminals
<|reference_start|>The Secret Key-Private Key Capacity Region for Three Terminals: We consider a model for secrecy generation, with three terminals, by means of public interterminal communication, and examine the problem of characterizing all the rates at which all three terminals can generate a ``secret key,'' and -- simultaneously -- two designated terminals can generate a ``private key'' which is effectively concealed from the remaining terminal; both keys are also concealed from an eavesdropper that observes the public communication. Inner and outer bounds for the ``secret key--private key capacity region'' are derived. Under a certain special condition, these bounds coincide to yield the (exact) secret key--private key capacity region.<|reference_end|>
