摘要： A method includes receiving a first message from a client device requesting an establishment of a transmission control protocol connection, wherein the first message contains a first sequence number for the transmission control protocol connection, calculating, based on the first sequence number and a first integer from a list of a plurality of randomly generated integers, a second sequence number for the transmission control protocol connection, sending a second message to the client device in response to the first message, wherein the second message contains the second sequence number, receiving a fourth message containing an acknowledgement number, extracting a second integer from the acknowledgement number, determining whether the fourth message originated with the client device by comparing the second integer to the first integer, and sending a fifth message to the client device, wherein a type of the fifth message is selected based on an outcome of the determining.
