摘要： In an embodiment, an existing transport protocol connection though a mobile device is recognized as having entered a state of disconnect. A lowest received sequence number is determined from received messages to be transmitted over a disconnected transport protocol connection. A disconnect acknowledgement message with a receive window of zero and a sequence number of one less than the lowest received sequence number is transmitted. The disconnect acknowledge message with a receive window of zero and a sequence number of one less than the lowest received sequence number is continued to be transmitted until the transport protocol connection exits the disconnect state to a connect state.

摘要： Approaches for preventing TCP data injection attacks in packet-switched networks are disclosed. An ACK message or dummy segment is sent to verify the authenticity of the data in the re-assembly buffer, and to help discard spurious data faster. These approaches involve the sender in detection of spurious data, and make improved use of mechanisms for processing ACK messages that are native to typical TCP implementations. The latter approach may be implemented without modification of the sender's TCP implementation. Further, the receiver's TCP implementation maintains compatibility with RFC 793.
摘要翻译：公开了在分组交换网络中防止TCP数据注入攻击的方法。发送ACK消息或虚拟段以验证重新组装缓冲区中的数据的真实性，并帮助更快地丢弃伪数据。这些方法涉及发送方检测虚假数据，并且改进了用于处理典型TCP实现本身的ACK消息的机制。可以在不修改发送者的TCP实现的情况下实现后一种方法。此外，接收机的TCP实现保持与RFC 793的兼容性。

摘要： Approaches for preventing TCP data injection attacks in packet-switched networks are disclosed. A first approach provides for dropping received segments that carry ACK values smaller than the next unacknowledged sequence number expected minus the maximum window size. This approach helps keep spurious injected segments out of the TCP re-assembly buffer. In a second approach, heuristics are used to examine the sequence number of a newly arrived segment, and when the sequence number is the next expected, then the newly arrived segment is used and the contents of the re-assembly buffer are not considered. Further, if the data payload of the newly arrived segment overlaps in sequential order with segments already in the re-assembly buffer, the overlapped segments in the re-assembly buffer are considered spurious and are discarded. Thus, this approach helps remove spurious data from the re-assembly buffer if the first approach somehow fails to prevent the data from entering the re-assembly buffer.
摘要翻译：公开了在分组交换网络中防止TCP数据注入攻击的方法。第一种方法提供丢弃接收的段，其携带ACK值小于预期的下一个未确认序列号减去最大窗口大小。这种方法有助于将伪注入的段保留在TCP重新组装缓冲区之外。在第二种方法中，启发式用于检查新到达的段的序列号，当序列号是下一个预期序列号时，则使用新到达的段，并且不考虑重新组装缓冲区的内容。此外，如果新到达的段的数据有效载荷与已经在重新组装缓冲区中的段按顺序重叠，则重组缓冲区中的重叠段被认为是虚假的并被丢弃。因此，如果第一种方法无法防止数据进入重新组装缓冲区，则此方法有助于从重新组装缓冲区中清除虚假数据。
