Information theoretic security study is based on minimal or no information leaked to malicious users. Secure network coding scheme could be simple but the study and optimality of the secure network coding is analysis is complex task. Complexity is due to the randomness and distribution of the source symbol though random key distribution can be modeled as per simplified coding scheme.
Secure Network Coding scheme not only promise to secure transmission but also challenge keep optimal information rate. Security level increases with the increasing random key field size and conversely information rate reduces. Hence optimality of secure network coding is realized very important study in Secure Network Coding theory.
