【摘要】:協(xié)議狀態(tài)機可以描述一個協(xié)議的行為,幫助理解協(xié)議的行為邏輯。面向文本類協(xié)議,首先利用統(tǒng)計學方法提取表示報文類型的語義關鍵字;然后利用鄰接矩陣描述報文類型之間的時序關系,基于時序關系進行協(xié)議狀態(tài)標注,構建出協(xié)議的狀態(tài)轉換圖。實驗表明,該方法可以正確地描述出報文類型的時序關系,抽象出準確的狀態(tài)機模型。
[Abstract]:Protocol state machines can describe the behavior of a protocol and help to understand its behavioral logic. For text-class protocols, the semantic keywords representing message types are extracted by statistical method, then the temporal relationships between message types are described by adjacency matrix, and the protocol status is annotated based on temporal relationships. The state transition diagram of the protocol is constructed. Experimental results show that the proposed method can correctly describe the temporal relationships of message types and abstract accurate state machine models.
