The Non─determinacy of Probability Model of Information Source and Generalized Information
Ye Sicong(Department of Mechanical and Electrical Engineering)
By analyzing the cognition characteristic and essence of Shannon informa-tion, the existence condition and classification of information source are discussed. On the basis of the feature of modeling information source and the influence of key randomness on ciphertext probability model, we put forward generalized information source described by random probability model and generalized information source entropy. Moreover we gener-alized Shannon information into premise information and generalized information, and proved that for deterministic division (or information symbol set) the sum of the two kinds of information is conservative.
