摘要：
The present invention relates to a method for data inspection, wherein said data is provided in parts, wherein for inspecting said data said parts are checked upon matching one or more predefined signatures, wherein said method being performed in a memory available to a computational device, by said checking device upon receiving an out-of order part of a sequence of parts, said part is checked for matching in forward and backward direction of said sequence, and the forward state and the backward state of said both checkings are temporarily saved, and upon receiving an in-order part of said sequence said part is checked for matching in forward direction of said sequence and if said packet is within a gap between the first part and the last part of said sequence said part is also checked for matching in backward direction of said sequence, wherein said backward state or said forward and backward state are updated or temporarily saved.
摘要（中）：
数据检查方法技术领域本发明涉及一种用于数据检查的方法，其中所述数据是以部分方式提供的，其中为了检查所述数据，在匹配一个或多个预定义签名时检查所述部分，其中所述方法在 计算设备可用的存储器，所述检查设备在接收到部分序列的无序部分时，检查所述部分在所述序列的正向和反向方向上的匹配，并且检查所述部分的正向状态和向后状态 所述两种检查都暂时保存，并且在接收到所述序列的有序部分时，检查所述部分是否在所述序列的正向上匹配，并且如果所述分组在所述序列的第一部分与最后部分之间的间隙内， 还检查所述序列的后向匹配，其中所述后退状态或所述前进和后退状态被更新或临时保存。
