Based on the above terminal device architecture, but not limited to the above architecture, the method embodiments of the present application are presented.
Referring to fig. 2, fig. 2 is a flowchart of a first exemplary embodiment of a message information hiding method according to the present application. The message information hiding method comprises the following steps:
step S210, a first message is obtained, wherein the first message comprises a message header and a communication identifier;
the execution main body of the method of the embodiment may be a message information hiding device, or may be a message information hiding terminal device or a server, and the embodiment uses the message information hiding device as an example, where the message information hiding device may be integrated on a terminal device such as a personal digital assistant, a smart phone, a tablet computer, etc. with a data processing function.
The scheme of the embodiment mainly realizes message information hiding of the message, particularly the message, and improves the message information hiding efficiency.
The embodiment starts from the practical problem of coping with high bandwidth and high concurrency, considers the information hiding aspect and the processing performance aspect of the message, designs a network address conversion behavior method for improving the transmission control protocol, solves the technical problem that the high bandwidth and high concurrency are difficult to cope with, and improves the efficiency of message information hiding.
It should be noted that the present embodiment may be applied to an IPv4 network, an IPv6 network, or other IP networks.
The first message is a data unit exchanged and transmitted in the network, namely a data block to be sent by the station, namely an IP message. The IP packet contains the complete data information to be transmitted. Wherein, the IP message comprises an IP header. The IP header is used to specify the source IP address, destination IP address, direct IP fragmentation and reassembly, and partial communication behavior of the IP communication.
Step S220, according to the communication identification, information replacement is carried out on the message header, and a first message with hidden information is obtained.
Specifically, in some actual scenes, the user does not allow the other party to acquire the own real source address, so that the own real source address can be further hidden by hiding the message information. For example, a private network accesses a public network, and the security of accessing the public network is improved by hiding message information; or one group accesses the resource information of other groups, and the other groups cannot acquire which group is accessing the resource information by hiding the message information. That is, through network address translation, internal device addresses or real server addresses may be hidden.
The embodiment is based on the scheme of traditional Network Address Translation (NAT), not only modifies the IP address, transmission control protocol or user datagram protocol port of the IP message, but also replaces the message header of the IP message, thus, after the IP message is subjected to network address translation, the IP address, port number and IP message header of the IP message are all changed, and the hiding effect of the real message information is improved.
According to the scheme, the first message is obtained, wherein the first message comprises a message header and a communication identifier; and according to the communication identification, carrying out information replacement on the message header to obtain a first message with hidden information. By replacing the message header according to the communication identifier to obtain the message with the hidden message, the technical problem that the high bandwidth and high concurrency are difficult to deal with can be solved, and the efficiency of message information hiding is improved.
Referring to fig. 3, fig. 3 is a flowchart of a second exemplary embodiment of a message information hiding method according to the present application. Based on the embodiment shown in fig. 2, the message header includes an IP header and a TCP header, and step S220 includes replacing information of the message header according to the communication identifier to obtain a first message with hidden information, where the first message includes:
and step S300, respectively replacing the information of the IP header and the TCP header according to the communication identifier to obtain a first message with the hidden information.
Specifically, the IP packet includes an IP header and a TCP header. Under the traditional network address conversion scheme, the embodiment also performs information replacement for the IP header and the TCP header, except that the port of the transmission control protocol or the user datagram protocol is modified according to the requirement for the IP address of the message. Therefore, after the conversion of the network address and the header information, the IP address and the port number of the IP message are changed, and the IP header and the TCP header are both changed, so that the hiding effect of the real message information is improved.
Further, the communication identifier includes one or more of an address and a port, and step S300 includes respectively replacing information of the IP header and the TCP header according to the communication identifier to obtain a first message after the information is hidden, where the first message includes:
step S310, according to the address and the port, replacing the TCP header with information to obtain a TCP header with hidden information;
the present embodiment is exemplified by the implementation of step S310 before step S320, and in other embodiments, step S310 may be implemented after step S320, or step S310 may be implemented synchronously with step S320.
Specifically, the communication identifier includes one or more of an address and a port. The address comprises a source IP address and/or a destination IP address of the IP message; the ports include source and/or destination ports of TCP or UDP. In this embodiment, for the transmission control protocol, a new TCP header is generated according to the source IP address and/or the destination IP address, the source port and/or the destination port of the IP packet, and the original TCP header is replaced with the new TCP header, so as to obtain the TCP header after information hiding.
Step S320, according to the address, carrying out information replacement on the IP header to obtain an IP header with hidden information;
specifically, a new identification number of the IP header is generated according to the source IP address and/or the destination IP address of the original IP message, and the original identification number is replaced by the new identification number, so that the identification number after information hiding is obtained.
Step S330, obtaining the first message after information hiding based on the IP header after information hiding and the TCP header after information hiding.
Specifically, the embodiment is based on the scheme of traditional network address conversion, so that the IP address, the transmission control protocol or the port of the user datagram protocol of the IP message is modified, and the IP header and the TCP header of the IP message are also modified. Therefore, the high performance and high concurrency of the network address conversion scheme can be utilized, and the information such as the identification number of the IP header, the serial number of the TCP header, the confirmation number and the like can be hidden, so that the performance and the function are considered.
According to the scheme, the TCP header is replaced by information according to the address and the port, and the TCP header with hidden information is obtained; according to the address, carrying out information replacement on the IP header to obtain an IP header with hidden information; and obtaining the first message after information hiding based on the IP header after information hiding and the TCP header after information hiding. By hiding the information of the identification numbers of the TCP header and the IP header, the technical problem that high bandwidth and high concurrency are difficult to deal with can be solved, and the efficiency of message information hiding is improved.
Referring to fig. 4, fig. 4 is a flowchart of a third exemplary embodiment of a message information hiding method according to the present application. Based on the embodiment shown in fig. 3, the TCP header includes a first sequence number, and step S310, performing information replacement on the TCP header according to the address and the port to obtain a TCP header with hidden information, including:
step S410, generating a second serial number of the TCP header according to the address and the port;
the sequence number (SEQ) is used for packet transmission after connecting to the network, the acknowledgement number (ACK) is used for acknowledgement of the received packet, and the value of the acknowledgement number is the sequence number of the packet waiting to be received.
Specifically, in the present embodiment, the communication identifier includes one or more of an address, a port, and a current time, and one or more of the current time. The IP message comprises an IP header and a TCP header, the TCP header comprises a serial number, the first serial number is an initial serial number in the TCP header, and the second serial number is a new serial number generated according to the address, the port and the current time of the IP message. The address comprises a source IP address and/or a destination IP address of the IP message; the ports include source and/or destination ports of TCP or UDP.
And step S420, replacing the first sequence number with the second sequence number to obtain the TCP header with the hidden information.
Specifically, for the transmission control protocol, according to the IP address, the port and the current time of the original message, a new sequence number of the TCP header is randomly generated, and the initial sequence number in the replacement message is the new sequence number, so that the sequence number and/or the acknowledgement number information in the TCP header can be hidden, and the accuracy of replacing the sequence number information is improved.
When the network address is converted, the IP address and the port number of the IP message are changed; and information replacement is performed on the sequence numbers in the TCP header, so that the sequence numbers and/or the acknowledgement numbers of the TCP header of the IP message are changed. Therefore, the high performance and high concurrency of the network address conversion scheme can be utilized, and the information such as the serial number and/or the acknowledgement number of the TCP header can be hidden, so that the performance and the function are both considered.
Further, step S220, after performing information replacement on the header of the message according to the communication identifier to obtain the first message with the hidden information, further includes:
step S430, recording a sequence difference value between the first sequence number and the second sequence number;
specifically, each byte in the byte stream that is transmitted in the TCP connection is numbered in sequence. For example, if the sequence number field value of one segment of message is 301 and the carried data has 100 fields, the next message
The data sequence number of the segment should start at 401. Thus, the sequence difference value is information hidden for the conversion of the sequence number of the IP message following the current message, more specifically for the initial sequence number in the TCP header of the IP message.
Step S440, receiving a second message;
specifically, the second message is a TCP message or an IP message after the current message.
Step S450, obtaining the second message with hidden information based on the second message and the sequence difference value.
Specifically, when the initial sequence number in the replaced TCP header is a new sequence number, the difference between the new sequence number and the initial sequence number is recorded, so as to facilitate the conversion of the sequence number of the subsequent IP message.
5 it should be noted that Transmission Control Protocol (TCP) is communication for connection between client and server
The protocol, using TCP, can connect the client and the server. Through the three-way handshake connection, the TCP can ensure that the information can be transferred to the receiving end without any difference of network environments. The embodiment of the application uses three-way handshake connection as an example, and the specific steps can be as follows:
when a client sends a message carrying an initial sequence number to a server, generating a new sequence number SEQ1 according to the address and a 0 port of the message, replacing the initial sequence number in the message with the sequence number SEQ1 to obtain the message carrying the sequence number SEQ1, and recording the sequence difference value between the initial sequence number and the sequence number SEQ 1;
when receiving a message carrying a sequence number SEQ1 and replying a response message carrying a confirmation number to a client, the server generates a new confirmation number ACK1 according to the address and the port of the response message and according to the sequence difference value,
obtaining a sequence number SEQ2, wherein the initial acknowledgement number in the replacement response message is acknowledgement number ACK1, and the initial sequence number in the response message of the replacement server 5 is sequence number SEQ2, so as to obtain the response message carrying ACK1 and SEQ2
Recording the difference value between the initial acknowledgement number and acknowledgement number ACK 1;
when receiving a response message carrying ACK1 and SEQ2, the client obtains a new acknowledgement number ACK2 based on the sequence difference value and obtains a new sequence number SEQ3 based on the acknowledgement number difference value,
and the initial acknowledgement number in the response message of the replacement client is acknowledgement number ACK2, the initial sequence number is sequence number 0 SEQ3, and the response message carrying the ACK2 and the SEQ3 is sent to the server to complete three-way handshake connection.
In addition, the client and the server of the transmission control protocol have serial numbers and confirmation numbers respectively, and record corresponding serial differences and confirmation differences at the same time.
According to the scheme, the second serial number of the TCP header is generated according to the address and the port; replacing the first serial number with the second serial number to obtain a TCP header with the hidden information; recording a sequence difference value of the first sequence number and the second sequence number; receiving a second message; and obtaining the second message after information hiding based on the second message and the sequence difference value. By replacing the sequence number in the TCP header with information and recording the sequence difference value, the accuracy and efficiency of the sequence number information hiding can be improved.
Referring to fig. 5, fig. 5 is a flowchart of a fourth exemplary embodiment of a message information hiding method according to the present application. Based on the embodiment shown in fig. 3, the IP header includes a first identification number, and step S320, according to the address, performs information replacement on the IP header to obtain an IP header with hidden information, including:
step S510, generating a second identification number of the IP header according to the address;
note that, the identification number (Identifier): the length of the IP messages forwarded in the IP network may be different, but if the message length exceeds the maximum length supported by the data link, the message needs to be split into several small fragments to be transmitted over the link. For example, the maximum length (MTU) of data in an ethernet frame is 1500 bytes, and each packet that is larger than the MTU is split to have the same value, i.e. an identification number, by which it is determined that the packet is the same IP packet.
Specifically, in the present embodiment, the communication identifier includes one or more of an address, a port, and a current time. The IP message comprises an IP header, the IP header comprises an identification number, the first identification number is an initial serial number in the IP header, and the second serial number is a new serial number generated according to the address of the IP message and the current time. The address comprises a source IP address and/or a destination IP address of the IP message; the ports include source and/or destination ports of TCP or UDP.
Step S520, replacing the first identification number with the second identification number to obtain the identification number after the information is hidden.
Specifically, a new identification number is randomly generated according to the source and destination IP addresses and time of the original message, the new identification number is used for replacing the initial identification number and is stored in the IP message, and the accuracy of replacing the serial number information can be improved.
When the network address is converted, the IP address and the port number of the IP message are changed; and information replacement is carried out on the identification number in the IP header, so that the identification number of the IP header of the IP message is changed. Therefore, the high performance and high concurrency of the network address conversion scheme can be utilized, and information such as the identification number of the IP header can be hidden, so that the performance and the function are considered.
Further, step S220, after performing information replacement on the header of the message according to the communication identifier to obtain the first message with the hidden information, further includes:
step S530, recording the identification difference value of the first identification number and the second identification number;
specifically, since the lengths of the IP packets forwarded in the network may be different, if the packet length exceeds the maximum length supported by the data link, the packet needs to be split into several small fragments to be transmitted on the link. For example, the maximum length (MTU) of data in an ethernet frame is 1500 bytes, and all packets larger than the MTU are split, and each packet to be split has the same value, i.e. an identification number, by which it is indicated that it is the same IP packet. Therefore, the identification difference value is used for information hiding of the messages of the same IP packet.
Step S540, receiving a third message;
specifically, the third message is an IP message or a TCP message after the current message.
It should be noted that, the third message may be the same message as the second message in step S440, so that when obtaining other messages except for the current message, the sequence number information in the TCP header and the identification number information in the IP header may be replaced simultaneously for the subsequent messages.
Step S550, obtaining the third message with hidden information based on the third message and the identification difference value.
