Description

Technical Field

[0001] The present invention belongs to the field of electric power technology, and in particular relates to a method and system for detecting the consistency of software versions of a power distribution terminal. Background Art

[0002] With the increasing development of computer technology, the level of power distribution automation technology is constantly improving, and the detection of power distribution terminals is becoming more scientific, comprehensive and standardized. Unified and standardized detection work ensures the correct function, stability and reliability of on-site terminal equipment. However, in actual use, there are cases where equipment does not operate normally due to human operation errors, unauthorized upgrades or even malicious tampering, which harms power production activities. How to eliminate this phenomenon and ensure that the software actually deployed on the terminal on site is completely consistent with the software that has passed the test is a key factor in ensuring the stable operation of the terminal on site and is an issue that needs to be solved urgently.

[0003] At present, the software version control and consistency detection methods of power distribution terminals mostly adopt manual comparison, which only compares the software name and size. However, even if the software size and name are exactly the same, it cannot guarantee that the software content and version are completely consistent, and there is a possibility of tampering. To address this problem, the current mainstream technologies include: type recognition based on content-related lexical analysis, feature code extraction based on text comparison heuristic operation, structure analysis based on source code, comparison based on file summary, feature code formation based on HASH value check and file fragments, and other external means such as logs, digital signatures and other methods. However, the software of power distribution terminals has diverse characteristics, and the hardware environment and operating system in which it is deployed vary greatly. The analysis and comparison method based on content or source code is fast and accurate, but it is not feasible in operation; the current method based on HASH value check and file fragments only partially enhances the anti-collision property of file feature codes, but if the version control requirements are to be met, the resource consumption is large; as for other external means, because they do not start from the file content itself, they cannot prevent deliberate human tampering. Summary of the invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art in the distribution terminal software version control and consistency detection method, such as incomplete detection content, easy tampering, difficult manual version management, and easy detection errors, the present invention proposes a distribution terminal software version consistency detection method and system.

[0027] When the priority is the third priority, a CRC32 algorithm is used to calculate and generate a third priority check word according to the third priority information.

[0028] The seventh preferred technical solution provided by the present invention is improved in that the software version consistency detection result is obtained according to the comparison result, including:

[0029] The eighth preferred technical solution provided by the present invention is improved in that the identification code string is generated by using a verification algorithm based on information of the standard version software corresponding to the software.

[0055] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0056] Embodiment 1:

[0057] A flow chart of a method for detecting the consistency of software versions of a power distribution terminal provided by the present invention is as follows: Figure 1 As shown, including:

[0058] Step 1: Calculate the software check word using a verification algorithm based on the information of the software running on the power distribution terminal;

[0059] Step 2: Obtain the identification code string corresponding to the software information;

[0060] Step 3: Compare the verification word with the identification code string, and obtain the software version consistency detection result based on the comparison result.

[0061] It should be noted that in this embodiment, step 1 and step 2 are only used to distinguish different steps, and the order of the two steps is not limited. For example, step 1 can be executed before step 2, or after step 2, or at the same time.

[0062] Specifically, a method for detecting the consistency of software versions of a power distribution terminal is as follows: Figure 2 As shown, including:

[0063] Step 101: Collect the software running on the power distribution terminal and the identification serial code of the software;

[0064] Automation maintenance personnel of power supply companies in various cities obtain the software running on the terminal and the identification code string of the software through the distribution terminal itself. The identification code string is pre-generated based on the standard version of the software that has been tested and issued to the terminal manufacturer as the "identity card" of the model and version of the firmware, that is, the running software, and also as the key information for the manufacturer to apply for "identity authentication" in the future. When providing the distribution terminal, the terminal manufacturer also provides a DNA code string, that is, an identification code string for verification. The identification code string can be provided in the form of a QR code. The identification code string is binary data.

[0065] Step 102: Calculate the verification word using a verification algorithm according to the information of the software;

[0066] Specifically, the software information is as follows: Figure 3 As shown, it includes content, size, name, version number, detection time, release date, release / change description, file update time and remarks; in addition, it can also include storage segments. Software information is prioritized according to its importance.

[0067] Among them, content and size are the first priority information, which is key information and is represented by S;

[0068] Name, version number and detection time are the second priority information, which is important information and is represented by L1;

[0069] Release date and release / change description are the third priority information, which is general information and is represented by L2; the optional software information storage section is also in L2;

[0070] File update time and remarks information are the fourth priority information, which is reference information and is represented by L3.

[0071] S-level critical information needs to solve the collision problem, and two heterogeneous algorithms are used to form a two-choice 2oo2 combined fault safety verification mechanism, such as Figure 4 As shown, the verification is passed only when the check words obtained by the two algorithms are consistent. That is, the S-level information uses at least two encryption methods to process the S-level information, and the results obtained by different encryption methods are combined to generate the S-level check word. Specifically, the two encryption methods include the information-digest algorithm MD5 and the cyclic redundancy check algorithm CRC32; according to the string generated by merging the software content and size information, the MD5 code and the CRC32 code are calculated respectively, and the two are combined to form a string, which constitutes the S-level check word, that is, the first priority check word.

[0072] Level L1 is important information and needs to participate in the verification operation. After the name and version number are combined to generate a string, the MD5 algorithm is used to obtain the corresponding MD5 code. The monitoring time of level L1 has special application requirements, and it is necessary to provide reversible conversion on the basis of the verification word. In this invention, a simple algorithm is considered to be used to take the inverse code of the field to be encrypted and then convert it to generate a time code value. The MD5 code corresponding to the name and size and the time code value together constitute the L1 level verification word, which is the second priority verification word.

[0073] Level L2 is general information and needs to participate in the verification operation. After the storage segment, release date and release / change description information are combined to generate a string, the CRC32 algorithm is used to obtain the corresponding CRC32 as the L2 level verification word, that is, the third priority verification word.

[0074] L3 is for reference only and is only included in the test report as a note.

[0075] The S-level check word, L1-level check word and L2-level check word together constitute the software's check word, which is binary data.

[0076] Step 103: Compare the verification word with the identification code string;

[0077] That is, the S-level check word is compared with the value of the corresponding position of the S-level in the identification code according to the preset position rule, the L1-level check word is compared with the value of the corresponding position of the L1-level identification code string, and the L2-level check word is compared with the value of the corresponding position of the L2-level identification code string.

[0078] Step 104: Obtaining a software version consistency detection result according to the comparison result and processing it;

[0079] Specifically include:

[0080] When the values ​​of the S-level check word and the corresponding position of the identification code string are different, the software consistency detection inconsistent conclusion is given, an error alarm is issued, and it is recorded in the detection report;

[0081] When the values ​​of the L1 level check word and the corresponding position of the identification code string are different, a conclusion of missing or inconsistent important information is given, an important alarm is issued, and recorded in the test report;

[0082] When the L2 level check word is different from the value of the corresponding position of the identification code string, a general conclusion of missing or inconsistent information is given, a general alarm is issued, and recorded in the test report;

[0083] Record the L3 level information as a note in the test report.

[0084] The error alarm, important alarm, and general alarm correspond to the alarm levels when the verification word detection results of different priorities are inconsistent, respectively, and are intended to distinguish the verification word detection results of different priorities in different alarm modes, and the specific expression forms and literal meanings of the three are not strictly limited. For example, in other embodiments, the error alarm, important alarm, and general alarm can also be expressed in the form of a first-level alarm, a second-level alarm, a third-level alarm, etc.

[0085] Embodiment 2:

[0086] The present invention also provides a method for generating a software identification code string of a power distribution terminal, such as Figure 5 As shown, specifically including:

[0087] Step 201: Generate a base string of the identification code string;

[0088] A simple random algorithm is used to continuously generate 64 random numbers modulo 65536 with the current time as the seed. The hexadecimal numbers are concatenated together to form a 128-byte binary string, which is the base string of the identification code string.

[0089] Step 202: Obtain information of the tested standard version software corresponding to the power distribution terminal software;

[0090] That is, the content, size, name, version number, detection time, release date, release / change description, file update time and remarks of the tested standard version software corresponding to the power distribution terminal software are obtained. Among them, the content and size are S-level information, the name, version number and detection time are L1-level information, the release date and release / change description are L2-level information, and the file update time and remarks are L3-level information.

[0091] Step 203: Calculate the S-level verification word;

[0092] The MD5 algorithm and the CRC32 algorithm are respectively used to calculate the MD5 code and the CRC32 code of the S-level information; the MD5 code and the CRC32 code of the S-level information are combined to form the S-level verification word;

[0093] Step 204: Calculate a portion of the L1 level check word;

[0094] Using the MD5 algorithm, the name and version number in the L1 level information are combined into a string and then the MD5 code is calculated as part of the L1 level verification word;

[0095] Step 205: Calculate the L2 level check word;

[0096] Adopt CRC32 algorithm, combine L2 level information into a string and calculate CRC32 code as L2 level check word;

[0097] Step 206: Calculate the time code value and generate the L1 level check word;

[0098] Since the detection time in the L1 level information has special application requirements, it is necessary to provide reversible conversion based on the verification word. In the present invention, a simple algorithm is considered to generate a time code value after taking the inverse of the field to be encrypted; the time code value and the MD5 code calculated by the L1 level information constitute the L1 level verification word.

[0099] Step 207: Generate an identification code string.

[0100] That is, the S-level, L1-level and L2-level check words are input into the base string of the identification code string according to the preset position rules to generate the identification code string, as follows:

[0101] According to the definition of step 203-step 206, the S-level information check word needs to occupy 20 bytes (16+4), the MD5 code in the L1-level information check word needs to occupy 16 bytes, the L2-level information check word needs to occupy 4 bytes, and the time code value of the "detection time" needs to occupy 8 bytes (7 bytes CP56time2a+0x00), totaling 48 bytes of valid bytes. In the base string of the identification code string, the starting bytes 3, 34, 55 and 89 are selected from the Fibonacci sequence, and the 20 bytes of information starting from the 3rd byte are replaced with the S-level check word, the 16 bytes of information starting from the 34th byte are replaced with the MD5 code in the L1-level check word, the 4 bytes of information starting from the 55th byte are replaced with the L2-level check word, and the 8 bytes of information starting from the 89th byte are replaced with the time code value in the L1-level check word. The preset position rule, that is, the filling rule of the identification code string, can be found in Figure 6 The base string of the identification code string with the check word input is byte-segmented and then rank-shifted, and a new binary string is generated after the reverse order is arranged. Figure 7 , convert the binary string into ASCII code. The fixed length 256-byte ASCII code string is the final output identification code string, which is irreversible.

[0102] Embodiment 3:

[0103] The present invention provides a distribution terminal software version archiving process, such as Figure 8 As shown, including:

[0104] Step 301: After the terminal software of different manufacturers, different models and different versions pass the function test of the Institute of Electrical Engineering, they are archived through an archiving tool and a unique identification code string is generated;

[0105] Step 302: The identification code string is sent to the terminal manufacturer as the "identity card" of the model and version of the firmware, and also as the key information for the manufacturer to apply for "identity authentication" in the future. The identification code string can be provided in the form of a QR code;

[0106] Step 303: The archiving tool stores the basic information corresponding to the identification code string, including the manufacturer, model, detection time, file name, content, size, storage segment, version number, release date, and some necessary release / change instructions and applicable scope, as a record in the local database to form an archive record.

[0107] Embodiment 4:

[0108] The following is a specific distribution terminal software version detection process, such as Fig. 9 As shown, including:

[0109] Step 401: Automation maintenance personnel of power supply companies in various cities can obtain the terminal identification code string and its software file only through the terminal itself;

[0110] Step 402: Determine whether the software information is complete, if so, proceed to step 403, otherwise proceed to step 405;

[0111] Step 403: Use the offline detection tool released by the Institute of Electrical Engineering to perform detection;

[0112] Step 404: Determine whether the test is passed, if yes, proceed to step 407, otherwise proceed to step 405;

[0113] Step 405: Provide the software, manufacturer, model and other related information, submit to the Institute of Electrical Engineering for testing, compare with the archived records, and generate a consistency report;

[0114] Step 406: Feedback the consistency report to the terminal manufacturer and ask for rectification within a specified period of time;
