Matrix row for empty-channel authorization
Read as: Given the public challenge, the observable transcript carries no mutual information about the hidden state.
Arguments
Operators
- I
- : mutual information used to measure effective leakage
- \mid
- : conditioning on the public challenge
- = 0
- : zero effective leakage in the model-scoped ITS column
Significance: This is the formal axis that distinguishes the Channel Zero row from possession credentials, ZK artifacts, and PQ transport.
Computational contrast: JWT/TLS, passkeys, ZK systems, and PQ-TLS remain evaluated through possession, verification artifacts, or hardness calendars; this row asks whether the transcript leaks at all.
