[0046] Figure 2 It is a schematic diagram of the representation of the fingerprint code of the power equipment in the embodiment of the present invention, which shows in detail the format of the power equipment code and its bit configuration.

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0049] like Figure 1 As shown, the power software and hardware encoding method of this embodiment may specifically include the following steps: S101, generating a prefix code based on a country code, an industry code, and an enterprise code.

[0050] The fingerprint of power equipment can be divided into two parts: prefix code and suffix code, with " / " as the separator in the middle. The prefix code is fixedly composed of country code, industry code and enterprise code. Specific examples are as follows: The country code represents the country or region to which the specific power equipment belongs. The country code can be identified by two letters or numbers. For example, the code for China is "86".

[0051] The industry code represents a specific industry and is composed of 4 letters or numbers (numbers 0-9, letters AZ). The present invention is aimed at the power industry and is the power industry code, such as "1100".

[0052] Among them, the enterprise code identifies the specific enterprise or organization to which the power equipment belongs. It consists of two letters or numbers (numbers 0-9, letters AZ). The enterprise applies for registration with the Power Fingerprint Management Center and obtains a unique enterprise code identifier according to needs, such as "11".

[0053] S102, generating a device type code and a device status code according to a device type classification standard and a device status table.

[0054] In the specific implementation of this embodiment, the suffix code is customized and consists of a device type code, a device status code, a feature hash value, and a check code.

[0055] Among them, the equipment type is 4 digits long and consists of letters and numbers (numbers 0-9, letters AZ). This part is divided into main category code and sub-code according to the application scenarios and functional classifications of power equipment, that is, primary classification + secondary classification. The tree structure is expanded, the primary classification is 1 digit, and the secondary classification is 3 digits; the main category code is the major category of equipment, such as "power industrial control terminal", and the sub-category code is the sub-category of equipment, such as "distribution terminal" and "electricity meter" under the power industrial control terminal. The specific codes are shown in the following table, such as "0006" means the 006 sub-category of the 0 main category, indicating that it is a smart terminal.

[0056] Table 1

[0057] Among them, the status bit is used to indicate the current status of the device, which helps to quickly determine whether the device is in normal working condition. It is 1 bit long and consists of letters and numbers (numbers 0-9, letters AZ). It can support the update of 36 status bits, such as 0 for deactivation, 1 for operation, 2 for fault maintenance, and 3 for testing / experimentation.

[0058] S103, collect multi-dimensional data, generate basic information fingerprint library, operating system fingerprint library, chip fingerprint library and communication fingerprint library respectively according to equipment characteristics, obtain power equipment attribute information, form multi-dimensional data, generate multiple fingerprint libraries according to equipment characteristics, obtain equipment components based on different fingerprint libraries, perform hash operation based on equipment component selection strategy, merge hash values ​​of fingerprint components and perform hash operation again to obtain feature hash value; Equipment components include equipment basic information component, equipment operating system component, equipment chip component and equipment communication component; Step S103 mainly collects multi-dimensional data, and collects basic information fingerprint library, operating system fingerprint library, chip fingerprint library and communication fingerprint library information of power equipment through API (Application Programming Interface) calls, driver layer calls, SNMP (Simple Network Management Protocol), syslog (log management and remote log transmission protocol), etc.

[0059] These multidimensional data were measured for discrimination and stability, and some reliable and representative feature components (such as device type, device name, device model, device version, manufacturer and serial number) were selected from them.

[0060] The basic device information component is obtained by combining multiple basic information of the target device, including device type, device name, device model, device version, manufacturer and serial number. If some information is not obtained and is empty, the information is set to 0.

[0061] The device operating system component is obtained by merging the operating system information of the target device, including the operating system type, operating system name, operating system version, and operating system release information. If some information is not obtained and is empty, the information is set to 0.

[0062] The device chip component is obtained by combining the chip information of the target device, including the chip model and processor architecture. If a piece of information is not obtained and is empty, the information is set to 0. Chip models include ET872, SCM701, etc., and processor architectures include Cortex-A7, etc.

[0063] The device communication component is obtained by combining various communication information of the target device, including communication protocol, communication mode, port information and IP address. If some information is not obtained and is empty, the information is set to 0.

[0064] The communication protocols include DL / T698.45, DL / T645-2007, IEC 61850, modbus, TCP, etc.

[0065] The communication modes include RS-485 communication, RS-232 communication, Ethernet, HPLC carrier communication, Bluetooth, far infrared communication, LoRa, wireless public network or private network, and optical fiber communication. Each mode is represented by 0 / 1. If the device supports a certain communication mode, it is set to 1, and they are arranged in order. If all 9 modes are supported, the communication mode of the device is 111111111. If only Ethernet communication is supported, the communication mode of the device is 001000000.

[0066] The port information arranges the open ports in order. For example, if ports 23 and 8080 are open, the port information is "238080".

[0067] Since it is difficult for different types of devices to obtain information about each component, different device components are selected according to the fingerprint component selection strategy. The predefined strategies are as follows: The first strategy, code is H1111, Hash=H1+H2+H3+H4; The second strategy, code is H1011, Hash=H1+H3+H4; The third strategy, code is H1101, Hash=H1+H2+H4; The fourth strategy, code is H1110, Hash=H1+H2+H3; The fifth strategy, code is H1001, Hash=H1+H4; The sixth strategy, code is H1010, Hash=H1+H3; The seventh strategy, code is H1100, Hash=H1+H2; The eighth strategy, code is H1000, Hash=H1; Among them, H1 represents the basic information fingerprint component, H2 represents the operating system fingerprint component, H3 represents the chip fingerprint component, and H4 represents the communication fingerprint component. The 4-digit number in the code represents H1, H2, H3, and H4 from left to right. When the number is "1", it means that the fingerprint component is enabled, and when the number is "0", the device component is not enabled.

[0068] After obtaining each device component, perform hash operations on the device components to obtain hash values, merge the hash values ​​in order, and then perform another hash operation to cut off the last 40 bits to obtain the characteristic hash value.

[0069] Among them, hash operation refers to converting data of arbitrary length into a string of fixed length. This string is called a hash value or hash value. By performing hash operation on these 8 attribute elements, they can be mapped into a set of unique, fixed-length feature hash values.

[0070] The most important features of hash algorithms are: (1) Determinism: the same input will always produce the same output; (2) Fixed-length output: no matter how long the input data is, the hash function will generate a hash value of fixed length; (3) Anti-collision: it is difficult to find different inputs that have the same hash value, so hash algorithms can effectively prevent data from being tampered with.

[0071] The hash algorithm used in the present invention is the national secret algorithm SM3. Of course, this algorithm is not limited.

[0072] For example, taking a switch as an example, the adopted strategy is set to 1001, and the device components are obtained based on the basic information fingerprint library and the communication fingerprint library.

[0073] The device name in the basic information fingerprint database is H3C S3100V2-26TP-SI, the device model is H3C S3100V2-26TP-SI, the device version is unknown 0, the manufacturer is 0, and the serial number is 210235A0K7C126002633. The basic information component of the switch is H3C S3100V2-26TP-SIH3C S3100V2-26TP-SI00210235A0K7C126002633. After the SM3 hash operation, the component fingerprint is e621bac65c77d3fa94de15077bddce86caa879118565da103524298d8a1b7a45.

[0074] The communication protocol in the communication fingerprint library is IPSNMP. The switch supports RS-485 communication, RS-232 communication and Ethernet communication. The communication mode is 111000000. The port information is scanned by NMAP, and it is known that ports 22, 23 and 80 are open. The device port information is 222380, and the IP address is 192.168.1.100. The communication component of the switch is IPSNMP111000000222380192.168.1.100. After SM3 hash operation, the component fingerprint is: 8591625546ce4605f8ce128dda8f780bd64ff973ba38642e44fbefa170081300.

[0075] Since the device collection strategy is 1001, the combined basic information fingerprint component and communication fingerprint component are hashed to obtain: 0ea8482884f2d599bb92af0ce6d35bd9f0c6b3320c81fd0d9d05f426895db1ff, the characteristic hash value is e6d35bd9f0c6b3320c81fd0d9d05f426895db1ff.

[0076] At the same time, taking a certain smart terminal as an example, the strategy 1111 is adopted to obtain the device component based on the basic information fingerprint library, operating system fingerprint library, chip fingerprint library and communication fingerprint library.
