Agreement of a restricted secret key

- Summary
- Metrics

Abstract

A secret key agreement problem is proposed with the additional restriction that the key is a function of a given secret source. An inner bound to the achievable rates, error and secrecy exponents is derived. The maximum key rate strongly achievable with positive exponents is characterized. The result leads to class of admissible restrictions on the key functions that does not diminish the strongly achievable key rate.
