Detailed Description
Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and together with the description serve to explain the principles of the invention, and are not intended to limit the scope of the invention.
It is to be understood that technical terms, acronyms, and the like appearing hereinafter are prior art and those skilled in the art are able to understand their meanings based on context and are not described here too much for reasons of brevity.
In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the invention. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
The invention provides a protocol processing method, a device, equipment and a storage medium for multi-protocol conversion, which are respectively described below.
Referring to fig. 1, in one embodiment of the present invention, a protocol processing method for multi-protocol conversion is disclosed, including:
s101, acquiring first message data based on a first protocol sent by source equipment, wherein the first message data comprises first header field data and first data field data;
s102, converting the first header field data into second header field data based on the message format of the first protocol and the second protocol;
s103, encrypting the first data field data according to the second header field data to obtain second data field data;
s104, splicing the second header field data and the second data field data to obtain second message data based on the second protocol and sending the second message data to the target equipment.
The invention provides a protocol processing method for multi-protocol conversion, which comprises the steps of firstly converting first header field data in first message data into second header field data, then encrypting the first data field data in the first message data by using the converted second header field data to obtain second data field data, and then splicing the second data field data and the second data field data to obtain second message data sent to target equipment. After receiving the second message data, the target device can obtain the original first data field data by adopting the same decryption algorithm to decrypt the second data field data according to the second header field data, so that the conversion from the first protocol to the second protocol between the source device and the target device is realized, and the source device and the target device can normally communicate. Encryption is realized in the conversion process, and the aim of secret communication among devices with different protocols is fulfilled. Compared with the prior art, the intelligent hydropower station has the advantages that in the system erection process, protocol conversion scripts are not required to be configured for each device under the condition of ensuring information safety, the complexity of system construction in the intelligent hydropower station is reduced, and because of the complexity, the flexibility and the expandability of the system are improved, so that the intelligent hydropower station can be put into use without great modification of the system when the devices are replaced or upgraded, and has good application prospect.
In practice, a device or module running the method may be considered a virtual device connected between a source device and a target device. For the source device, the module running the method corresponds to a virtual device running the first protocol in communication therewith, and for the target device, the module running the method corresponds to a virtual device running the second protocol in communication therewith.
In a computer network, a network message consists of two partial fields: a Header field (Header) and a data field (Payload).
The Header is a fixed length region containing important metadata, typically a Header, located at the very beginning of a network message that needs to be transmitted to ensure that the corresponding part of the packet is understood and processed by a device such as a router in the internet or telephone network. The information in the header may provide important information about the network message, such as source address, destination address, protocol type, port number, etc. The header may contain different fields depending on the different protocols or packet types. The length and structure of the header fields and the data contained depend on the network protocol used.
The data field is a variable length region containing the transmitted data. When a network message is sent from one computer to another, its header portion may be processed by routers and other devices, where the information in the header may need to be used to determine the next destination of the message. After header processing is complete, the data portion of the digital data packet may be processed and restored at the destination computer using the protocol.
It can be understood that, in this embodiment, the data in the header field and the data field in the first packet data are the first header field data and the first data field data, the data in the header field and the data field in the second packet data are the second header field data and the second data field data, and the third packet data and the fourth packet data are the same. In practice, according to a specific protocol type, those skilled in the art will understand that the words such as the first header field data, the third data field data, etc. herein specifically refer to which data, and thus will not be described in detail hereinafter.
Specifically, in a preferred embodiment, the step S102, the converting the first header field data into the second header field data based on the message format of the first protocol and the second protocol specifically includes:
obtaining a public field of the first protocol and the second protocol according to the message format of the first protocol and the message format of the second protocol;
storing data of a non-public field in the first header field data;
and generating the second header field data, wherein the public field in the second header field data is filled with the data of the public field in the first header field data, and the non-public field in the second header field data is filled with the first preset filling data.
The common field in the above process is a field common to the first protocol and the second protocol, which is generally a field indicating the identity of the target device, such as a target IP address, a target MAC address, etc., which are necessary fields in each protocol, so that the content of the common field in the first header field data only needs to be filled into the second header field data in the above process.
The above-mentioned non-public field refers to a field not shared in different protocols, which is generally used to represent a sequence number, a message length, a protocol type, and the like of a message, and when the protocol conversion is performed, the first preset filling data can be filled in the non-public field for the second message data based on the second protocol, and the second message data can operate based on the second protocol.
In practical implementation, the device or module running the method can locally maintain an interaction list for recording data of non-public fields such as a message sequence number and the like when the device or module communicates with the target device based on the second protocol last time. When the second message data is generated, appropriate first preset filling data can be obtained according to the interaction list for filling.
Further, in a preferred embodiment, the step S103, encrypting the first data field data according to the second header field data to obtain second data field data specifically includes:
acquiring at least one public field as a first encryption basis field;
generating a first symmetric key according to the first encryption in the second header field data and the content in the field, and encrypting the first data field data according to the first symmetric key based on a first symmetric encryption algorithm to obtain the second data field data.
Since the data in the header field is normally related to the normal transmission of the message in the network, only the first data field data is encrypted in the present invention. Symmetric encryption is a common encryption algorithm, also known as private key encryption or shared key encryption. In a symmetric encryption algorithm, the same key (i.e., the first symmetric key described above) is used for encryption and decryption operations. The principle of symmetric encryption is that the original data is encrypted by using a secret key to generate a ciphertext, and then the ciphertext is decrypted by using the same secret key to restore the original data. Since the same key is used for encryption and decryption, the symmetric encryption algorithm has the characteristics of high efficiency, rapidness and simplicity. Common symmetric encryption algorithms are: DES (Data Encryption Standard), 3DES (Triple Data Encryption Algorithm), AES (Advanced Encryption Standard), etc.
In the invention, the target equipment can also receive the second header field data, and the target equipment can finish the decryption of the data only by configuring and operating the equipment of the method to adopt the same key generation algorithm and the symmetric encryption algorithm (namely the first symmetric encryption algorithm) so as to acquire the first data field data, thereby completing the communication with the source equipment.
The present invention also provides a more detailed embodiment for more clearly describing the above step S103:
assume that a source address, a destination address and a port number field in a public field are selected and used together as a first encryption basis field, wherein:
source address: 192.168.0.1;
target address: 10.0.0.1;
port number: 8080;
the content of the first data field data is: the data content is as follows: "Hello, world-! ";
then, the source address, the target address and the port number are spliced together to obtain a first encryption basis field, for example:
192.168.0.1-10.0.0.1-8080；
the string is then processed using a secure key generation algorithm (e.g., a hash function) to generate a first symmetric key:
x1y2z3a4b5c6d7e8；
the first data field data is encrypted using the generated first symmetric key. For example, the data field "Hello, world-! "encryption gets the second data field data:
d7e8x1y2z3a4b5c6；
and finally obtaining second message data:
the second header field data includes: source address: 192.168.0.1, target address: 10.0.0.1, port number: 8080;
the second data field data includes: d7e8x1y2z3a4b5c6.
It will be appreciated that the above procedure is only a simple example for ease of understanding and use, and that more complex encryption algorithms and security measures may be employed in practical applications.
When the source device does not need feedback data (for example, the source device is a device for temperature acquisition, water level acquisition and the like, and only needs to provide data), protocol conversion communication between the source device and the target device can be completed through the process. In some cases where feedback data is required, when the target device receives the second message data, it generates third message data of the response, and at this time, it is required to convert the third message data to answer the source device.
Thus, referring to fig. 1 again, in a preferred embodiment, the protocol processing method of multiprotocol conversion further includes:
s105, acquiring third message data based on the second protocol, which is sent by the target equipment, wherein the third message data comprises third header field data and third data field data;
s106, converting the third header field data into fourth header field data based on the message format of the first protocol and the second protocol;
s107, decrypting the third data field data according to the fourth header field data to obtain fourth data field data;
s108, splicing the fourth header field data and the fourth data field data to obtain fourth message data based on the first protocol and sending the fourth message data to the source equipment.
The principle and advantageous effects of the above process can be analogically described with reference to the foregoing, and will not be described here too much.
Further, in a preferred embodiment, the step S105 of converting the third header field data into fourth header field data based on the message format of the first protocol and the second protocol specifically includes:
obtaining second preset filling data according to the stored data of the non-public field in the first header field data;
and generating the fourth header field data, wherein the public field in the fourth header field data is filled with the data of the public field in the third header field data, and the non-public field in the fourth header field data is filled with the second preset filling data.
In step S102 before the present invention, the non-public field in the first header field data is reserved, and when the target device responds to the first message data (actually, responds to the second message data), the device or module running the method can generate the non-public field data corresponding to the first header field data according to the reserved non-public field, and fill the non-public field data into the fourth header field data, so that the protocol conversion of the message is completed, and the normal communication of the fourth message data is ensured.
Further, in a preferred embodiment, the step S107 decrypts the third data field data according to the fourth header field data to obtain fourth data field data, which specifically includes:
acquiring at least one public field as a second encryption basis field;
generating a second symmetric key according to the second encryption in the third header field data and the content in the field, and decrypting the third data field data according to the second symmetric key based on a second symmetric encryption algorithm to obtain the fourth data field data.
The second symmetric encryption algorithm in the above process may be implemented by the same encryption algorithm as the first symmetric encryption algorithm, or may be implemented by a different encryption algorithm. When different encryption algorithms are adopted, the information security can be obviously improved, and only two correct key generation algorithms and symmetric encryption algorithms are respectively configured on the equipment running the method and the target equipment.
In order to better implement the protocol processing method of multi-protocol conversion in the embodiment of the present invention, referring to fig. 2, fig. 2 is a schematic structural diagram of an embodiment of a protocol processing apparatus of multi-protocol conversion provided by the present invention, based on the protocol processing method of multi-protocol conversion, a protocol processing apparatus 200 of multi-protocol conversion provided by the embodiment of the present invention includes:
