Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The embodiment of the application provides an analysis method, equipment and a storage medium for a multi-version communication protocol, which solve the technical problem that a large amount of analysis resources are wasted in the existing multi-version communication protocol analysis method.
The following describes the technical scheme provided by the embodiment of the application in detail through the attached drawings.
Fig. 1 is a flowchart of an parsing method for a multi-version communication protocol according to an embodiment of the present application. As shown in fig. 1, the method for resolving multi-version communication protocols provided by the embodiment of the application specifically includes the following steps:
step 101, analyzing and extracting initial rules in a preset number of communication protocol versions, and dividing the initial rules in the preset number of communication protocol versions into a plurality of initial rule sets based on preset rule identifiers in the initial rules.
It should be noted that, in the embodiment of the present application, the number of resolved versions of the multi-version communication protocol should be greater than or equal to two. Because the compatibility problem is not required to be considered under the condition that the communication protocol has only one version, the communication protocol is processed through a protocol analysis model, and therefore, the analysis method of the multi-version communication protocol provided by the application is not required.
A communication protocol, which is a series of conventions that two parties of a communication in a data communication system should commonly adhere to in order to ensure that the parties can communicate efficiently and reliably, comprising: data format, sequence and rate, link management, flow regulation, error control, etc. Therefore, the communication protocol is composed of a plurality of rules, each rule corresponds to a unique rule type in the communication protocol version, and a preset rule identifier corresponding to the type is also arranged in the rules. In the embodiment of the application, the rules in the preset number of communication protocol versions are called initial rules, namely rules which are not processed by the method provided by the embodiment of the application.
Under the condition that the analysis versions of the communication protocol are the preset number (the preset number is more than or equal to two), the establishment of the initial rule set can firstly analyze any one of the preset number of communication protocol versions, then obtain a plurality of preset rule identifications according to analyzing any one of the communication protocol versions, and establish a plurality of initial rule sets based on the preset rule identifications. Then extracting the initial rule in any communication protocol version into a plurality of corresponding initial rule sets; and traversing other communication protocol versions except any one of the preset number of communication protocol versions to extract the initial rules in the other communication protocol versions into a corresponding plurality of initial rule sets. When preset rule identifiers corresponding to any one of the initial rule are in the preset number of communication protocol versions, and cannot be matched with the plurality of initial rule sets, an initial rule set named by the preset rule identifier corresponding to any one of the initial rule is established based on the preset rule identifier corresponding to any one of the initial rule, and any one of the initial rule is extracted into the initial rule set.
In the embodiments of the present application, the following examples are explained in detail.
Example one: the preset number of the analysis versions of the communication protocol is two, and the two versions of the communication protocol are respectively named as communication protocol 1.0 and communication protocol 2.0. The communication protocol 1.0 comprises two rules, and preset rule identifiers are respectively in a data format and a network connection mode; the communication protocol 2.0 comprises three rules, and preset rule identifiers are respectively a data format, a network connection mode and a verification mode. When the initial rule set is established, firstly, any communication protocol version in the communication protocol 1.0 and the communication protocol 2.0 is analyzed, and if the any communication protocol version is the communication protocol 1.0, the communication protocol version is analyzed to obtain two preset protocol identification data formats and network connection modes. Then, two initial rule sets are established according to the two preset protocol identifications, the two initial rule sets are respectively named as a data format rule set and a network connection mode rule set, and then the two rules in the communication protocol 1.0 are respectively added into the corresponding initial rule sets. The remaining communication protocol version, in this case communication protocol 2.0, is then traversed. Analyzing the communication protocol 2.0, determining that two initial rules of a data format and a network connection mode exist in the communication protocol 2.0, and respectively adding the two initial rules into two corresponding data format rule sets and network connection mode rule sets. An initial rule with a preset rule identifier as a verification mode also exists in the communication protocol 2.0, and the preset rule identifier is not matched with the data format and the network connection mode, so that an initial rule set named as a rule set of the verification mode is established based on the preset rule identifier of the verification mode to store the initial rule.
Step 102, determining a difference rule set and the same rule set in a plurality of initial rule sets, adding any one of the difference rule sets into the first rule set, and adding any one of the same rule sets into the solidified rule set.
In one embodiment of the present application, after dividing the initial rules in the preset number of communication protocol versions into a plurality of initial rule sets, it is necessary to determine whether each initial rule set is a difference rule set or the same rule set. It should be noted that the same rule set is a corresponding initial rule set in which the rule content of all initial rules in the rule set is the same and the number of the initial rules is equal to the preset number; the set of difference rules includes two types: the number of the initial rules is smaller than the preset number of the corresponding initial rule sets, and the corresponding initial rule sets with different rule contents of the two initial rules exist.
Specifically, the number of initial rules in any initial rule set is first determined, and if the number of initial rules in any initial rule set is smaller than a preset number, any initial rule set is determined to be a difference rule set.
It will be appreciated that, since the number of initial rules in any of the above initial rule sets is less than the preset number, there are at least one communication protocol version for which there is no initial rule corresponding to any of the above initial rule sets, and thus, the initial rule of this type is not applicable to all communication protocol versions, and thus, the initial rule set is a difference rule set.
And under the condition that the number of the initial rules in any initial rule set is equal to the preset number, matching the rule content of any initial rule in any initial rule set with the rule content of other initial rules one by one. When the rule content of all the initial rules in any initial rule set is the same, determining that any initial rule set is the same rule set; when the rule content of any two initial rules in any initial rule set is different, determining that any initial rule set is a difference rule set.
In the embodiment of the present application, the following second embodiment is used for explanation. The second example is an extension of the first example.
Example two: assume that the rule contents of two initial rules in the communication protocol 1.0 are respectively: "data type: the data type is ' message type ', and the message comprises ' message sequence number ', ' message content ', ' message tail ', ' network connection mode: the terminals are connected by 'TCP'. Assume that the rule contents of three initial rules in the communication protocol 2.0 are respectively: "data type: the data type is ' message type ', and the message comprises ' message sequence number ', ' message content ', ' message tail ', ' network connection mode: the terminals adopt ' UDP connection ' "and ' check mode: the checking mode is 'cyclic redundancy check'. Thus, the two initial rules contained in the data type rule set are: "data type: the data type is 'message type', and the message comprises 'message sequence number', 'message content', 'message tail', 'data type': the data type is 'message type', and the message comprises 'message sequence number', 'message content', 'message tail'; the two initial rules contained in the network connection mode rule set are: "network connection mode: the terminals adopt ' TCP connection ' "and ' network connection modes: the terminals are connected by adopting UDP connection'; one rule contained in the check mode rule set is: the "check mode is 'cyclic redundancy check'. Therefore, the number of the initial rules in the check mode rule set is smaller than the preset number two, and the check mode rule set is determined to be a difference rule set. Because the number of the initial rules in the data type rule set and the network connection mode rule set is equal to the preset number two, the initial rules in the two initial rule sets are respectively and randomly matched and judged, and whether two initial rules with different rule contents exist or not. Because the data type rule set and the network connection mode rule set have only two rules, the rule contents of the two initial rules in the data type rule set are the same through matching, and the rule contents of the two initial rules in the network connection mode rule set are different. Therefore, the data type rule set is determined to be the same rule set, and the network connection mode rule set is determined to be the difference rule set.
After determining a difference rule set of the plurality of initial rule sets and the same rule set, adding any one of the difference rule sets to the first rule set, and adding any one of the same rule sets to the solidified rule set.
In the embodiment of the present application, the following example three is explained in detail. The third example is an extension of the second example.
Example three: since the initial rules in the same rule set are all the same, the set of curing rules contains one initial rule: "data type: the data type is 'message type', and the message comprises 'message serial number', 'message content', 'message tail'. Since any one of the initial rules in the difference rule set is selected to be added to the first rule set, one initial rule may be optionally extracted into the first rule set, where the initial rules included in the first rule set are set as follows: "network connection mode: the terminals adopt ' UDP connection ' "and ' check mode: the checking mode is 'cyclic redundancy check'.
And 103, performing generalization processing on the initial rules in the first rule set, and adding the obtained generalization rules into the second rule set.
In one embodiment of the present application, before generalizing an initial rule in a first rule set, word classification is first required for the initial rule in the first rule set to determine a plurality of word corresponding to the initial rule in the first rule set; wherein the types of the word cards comprise any one or more of the following: words, numbers, symbols, marks; after classifying the word cards in the first rule set, the first rule set is in a disordered state, so that a plurality of word cards corresponding to the initial rule are required to be subjected to aggregation processing to generate a first word card sequence. It should be noted that, the aggregation processing is to integrate a plurality of word cards corresponding to the same initial rule to obtain a first word card sequence with a sequence of existence; the word card sequence comprises a plurality of word cards and the association relation among the word cards; the association relation among the word cards at least comprises the front-back sequence among the word cards.
In one embodiment of the present application, the generalization process is performed after the initial rule in the first rule set is classified into a word or a tablet, specifically: determining a first parameter word in the first word sequence based on the association relation among the words in the first word sequence; generalizing the first parameter word to generate a second word sequence; the generalization processing is to replace the first parameter word with the parameter to be instantiated; and then performing inverse word processing on the second word card sequence to convert the second word card sequence into a generalization rule. It should be noted that, the parameter word is a word representing an initial rule parameter in the first word sequence; reverse word processing is the process of converting a second word sequence into generalized rules.
In the embodiment of the present application, the following example four is explained in detail. The fourth example is an extension of the third example.
Example four: since the initial rules contained in the first rule set are: "network connection mode: the terminals adopt ' UDP connection ' "and ' check mode: the checking mode is 'cyclic redundancy check'. The word cards in the first rule set after word card classification are included in the first rule set: ", network connection mode,": terminal, gateway, use, ', UDP, connection,', ", check mode,: verification means, ', cyclic, redundant, verification,', ". In this example, the leading number of the double leading number may be used as the first word sign of the first word sign sequence, so that two first word sign sequences may be obtained: ", network connection mode,": terminal, gateway, application, ', UDP, connection,', "and" check mode,: verification means, ', cyclic, redundant, verification,', ". In this example, two mono-quotation marks are used as the front and back marks of the parameter marks, and the mark content between the two mono-quotation marks is determined to be the parameter mark. It should be noted that, as can be understood from the above word classification, since the word classification process is based on the meaning and type of the word, there is a case where the parameter is divided into a plurality of words, and therefore, when the generalization processing is performed, a plurality of words between two mono-numbered words may be replaced by one word. In this example, two second word sequences obtained by the following alternatives are given: ", network connection mode,": terminal, gateway, adoption, ', network connection mode parameters 1, ' AND ', verification mode,: checking mode, i.e., checking mode parameters 1,', ". And performing inverse word processing on the two second word card sequences to convert the second word card sequences into generalization rules, and adding the generalization rules to the second rule set. In this example, the two generalization rules are: "network connection mode: the terminals adopt network connection mode parameters 1' "and check modes: the verification mode is 'verification mode parameter 1' ".
It should be further noted that, because the instantiation parameters in the initial rule cannot be directly determined in the processing process of the processor, the embodiment of the application enables the processor to determine the instantiation parameters in the initial rule by using the word-board classification method, thereby realizing the process of replacing the instantiation parameters in the initial rule with the parameters to be instantiated, and generating the generalization rule. Wherein the instantiation parameter is a parameter with specific assignment; the parameters to be instantiated are parameters that have no specific assignment.
In one embodiment of the present application, after the obtained generalization rule is added to the second rule set, parameters in the difference rule set need to be extracted and stored in a preset difference rule parameter library, so that the generalization rule can replace parameters to be instantiated with instantiation parameters during parsing.
Specifically: firstly, classifying word cards of initial rules in a difference rule set to determine second parameter word cards corresponding to each initial rule in the difference rule set; and classifying the second parameter word corresponding to the difference rule set according to the communication protocol version to generate a preset number of difference rule parameter sets, and storing the preset number of difference rule parameter sets in a preset difference rule parameter library.
In the embodiment of the present application, the following fifth embodiment is explained in detail. The fifth embodiment is an extension of the second embodiment.
Example five: the two difference rule sets are respectively a network connection mode rule set: "network connection mode: the terminals adopt ' TCP connection ' "and ' network connection modes: the terminals adopt 'UDP connection' "and a check mode rule set: the "check mode is 'cyclic redundancy check'. The word classification process of the difference rule set is not performed any more, and it can be understood that the second parameter word obtained after word classification includes: TCP connection, UDP connection, cyclic redundancy check. Because the three parameter word cards respectively correspond to the two versions of the communication protocol, the three parameter word cards need to be classified according to the versions of the communication protocol, and a preset number of difference rule parameter sets are generated for distinguishing. In this example, two differential rule parameter sets are determined to be a communication protocol 1.0 differential rule parameter set and a communication protocol 2.0 differential rule parameter set, respectively, so that the communication protocol 1.0 differential rule parameter set includes one instantiation parameter of a TCP connection, and the communication protocol 2.0 differential rule parameter set includes two instantiation parameters of a UDP connection and a cyclic redundancy check. After determining the communication protocol 1.0 difference rule parameter set and the communication protocol 2.0 difference rule parameter set, the two parameter sets are stored in a preset difference rule parameter library. The preset difference rule parameter library is a database for storing the instantiation parameters corresponding to each initial rule in the difference rule set.
Step 104, under the condition that the protocol analysis model needs to analyze the communication protocol version to be analyzed, carrying out instantiation processing on the generalized rule in the second rule set based on the instantiation parameter corresponding to the communication protocol version to be analyzed stored in the preset difference rule parameter library so as to obtain the difference rule set to be analyzed.
In one embodiment of the application, when two terminals need to communicate according to the communication protocol version to be resolved, responding to the analysis signal of the communication protocol version to be resolved, determining a generalization rule to be instantiated in a second rule set, and determining a corresponding difference rule parameter set in a preset difference rule parameter library; and carrying out instantiation assignment on parameters to be instantiated in the generalization rule to be instantiated based on the parameter values stored in the difference rule parameter set so as to obtain a difference rule set to be analyzed.
