摘要: 該文簡要介紹了公用事業(yè)自動化收費系統(tǒng)的基本構(gòu)成,并就系統(tǒng)的數(shù)據(jù)安全性進行討論,提出了一個以隨機數(shù)確定數(shù)據(jù)傳輸順序,插入無效隨機數(shù)增大信息冗余,用哈希函數(shù)校驗,用一次性加密方法加密哈希值和隨機數(shù)的數(shù)據(jù)安全解決方案,有效防止系統(tǒng)數(shù)據(jù)遭受主動攻擊。Abstract: The structure of fee data automatically collecting system in public utility is introduced. With the study of the security of the system, a synthetic security scheme is put forth, which is using random number to decide the sequences of the data to be transmitted, inserting random numbers with no use to improve information redundance, using monodirectional hash function to get the exclusive value of the transmitted data and adopting the one time encrypt to encipher the hash value and the random number. This method is simple and highly efficient.
