And then the execution times of target instructions in the preset function accelerated by each key instruction set are calculated according to the preset name-quantity mapping table. Because processes can call a large number of preset functions (such as various hash functions) specified in the application when executing the consensus contract, and meanwhile, in order to obtain more rewards in the blockchain adopting the workload certification mechanism, the processes executing the consensus contract can call corresponding acceleration instruction sets (namely key instruction sets) when calling the preset functions. Therefore, in the application, the number of target instructions executed by the target process can be approximately determined by calling the information list D and the preset name-number mapping table. Therefore, the aim quantity list set B can be obtained by monitoring the calls of a few key instruction sets without monitoring each instruction executed by the computer.

In turn, a quick determination is made as to whether the target process is executing a specified consensus contract (i.e., a blockchain consensus contract that employs a workload certification mechanism).
Furthermore, the total number list NUM obtained in the application does not need to distinguish different instruction types, so that only a simple counter is adopted, and the consumption of great calculation force is avoided.

For example, an apparatus may be implemented and/or a method practiced using any number of the aspects set forth herein. In addition, such apparatus may be implemented and/or such methods practiced using other structure and/or functionality in addition to one or more of the aspects set forth herein.
Referring to fig. 1, in one aspect of the present application, there is provided a method for identifying a process executed by a specified consensus contract, including:
s100, in the target time period, determining call information corresponding to the currently called key instruction set when any key instruction set is called by the target process, so as to obtain a call information list D= (D) 1 ,D 2 ,…,D i ,…,D n );D i =(TIME i ,NAME i ) The method comprises the steps of carrying out a first treatment on the surface of the i=1, 2, …, n; wherein n is the number of times the target process calls the key instruction set in the target time period; d (D) i Call information corresponding to an ith key instruction set called for the target process; TIME (TIME) i Time, NAME, when the ith critical instruction set is invoked for the target process i An instruction set name of an ith key instruction set called for the target process; the execution of the key instruction set is used for accelerating the execution of the corresponding preset function. Specifically, the preset function may be a hash function such as SHA1, SHA256, and the like. The key instruction set may be SHA1MSG1, SHA1MSG2, SHA1NEXTE, SHA1RNDS4, SHA256MSG1, SHA256MSG2, SHA256RNDS2, etc.
Further, in some exemplary embodiments, the target process may call any one of the key instruction sets and obtain the corresponding call information by adding a preset information return instruction to each of the key instruction sets, so that when each of the key instruction sets is called and executed, the corresponding call information may be automatically returned, thereby avoiding the setting of the monitoring module to monitor the call operation of the process, and further reducing the calculation effort.
S200, determining a target quantity list set B= (B) according to the D and a preset name-quantity mapping table 1 ,B 2 ,…,B i ,…,B n ) The method comprises the steps of carrying out a first treatment on the surface of the Wherein B is i For D i The execution times of target instructions in a preset function corresponding to the acceleration of the key instruction set.
In this embodiment, the target instruction is pre-specified, and the number of the target instruction may be one or more, where the target instruction may include at least one of the following: bit operation instructions, floating point operation instructions, multiplication instructions, division instructions, subtraction instructions, addition instructions, vector operation instructions. Preferably, in the present application, the target instruction includes each of the above.
Specifically, the name-number mapping table Ys= (YS) 1 ,YS 2 ,…,YS b ,…,YS d );YS b =(YNANE b ,YN b ) The method comprises the steps of carrying out a first treatment on the surface of the b=1, 2, …, d; d is the number of preset key instruction sets; YS (YS) b Mapping relation information corresponding to a preset b-th key instruction set; YNANE b For the instruction set name corresponding to the preset b-th key instruction set, YN b And the mapping quantity corresponding to the preset b-th key instruction set.
In an exemplary embodiment of the present application, the step S200 includes:
s210, traversing D, if NAME i =YNANE b Then determine B i =YN b
S300, determining a total number list NUM= (NUM) according to D 1 ,NUM 2 ,…,NUM i ,…,NUM n ) The method comprises the steps of carrying out a first treatment on the surface of the Wherein NUM i For D i Corresponding total number, and if i=1, 2, …, n-1, NUM i For TIME i To TIME i+1 The total number of arbitrary instructions executed by the target process during the period of (1), if i=n, NUM i For TIME i To TIME i +(TIME n -TIME 1 ) And/or (n-1) the total number of arbitrary instructions executed by the target process during the time period.
In particularDue to D n Is the last time the target process called the key instruction set, so the time interval between the target process and the next time the key instruction set is called cannot be directly determined. Therefore, in this embodiment, the average value of each previous time interval is taken as the last time interval, so as to ensure the data accuracy in the subsequent processing process as much as possible.
S400, according to B and NUM, obtaining a target proportion list L= (L) 1 ,L 2 ,…,L i ,…,L n ) The method comprises the steps of carrying out a first treatment on the surface of the Wherein L is i For the ith target proportion, L i =B i /NUM i
S500, if PL > Y1 and FL < Y2, determining the target process as a specified consensus contract execution process. Wherein Y1 is a preset proportion threshold, Y2 is a preset proportion fluctuation threshold, PL is a key proportion, and FL is a proportion fluctuation value; pl= (Σ) i=1 n L i )/n;FL=((∑ i=1 n (L i -PL) 2 )/n) 1/2
The identification method of the specified consensus contract execution process provided by the embodiment can acquire call information corresponding to a called key instruction set when the target process calls any key instruction set for accelerating the execution of a corresponding preset function within a target time period. And then the execution times of target instructions in the preset function accelerated by each key instruction set are calculated according to the preset name-quantity mapping table. Because the process executes the consensus contract, a large number of preset functions (such as various hash functions) specified in the embodiment are called, and meanwhile, in order to obtain more rewards in the blockchain adopting the workload certification mechanism, the process executing the consensus contract calls a corresponding acceleration instruction set (i.e. a key instruction set) at the same time when the preset functions are called. Therefore, in this embodiment, the number of target instructions executed by the target process can be approximately determined by calling the information list D and the preset name-number mapping table. Therefore, the aim quantity list set B can be obtained by monitoring the calls of a few key instruction sets without monitoring each instruction executed by the computer. Thereby reducing the computational effort required in determining the number of target instructions to be executed by the target process.
Moreover, since normal secure encryption processes and machine learning processes, while also executing target instructions in large numbers, such normal processes do not call critical instruction sets in the present application in large numbers. Therefore, the execution quantity of the target instruction determined by the method provided by the application is more accurate, and the normal safe encryption process, the machine learning process and the like can be directly filtered out, so that the false alarm rate is reduced.
Meanwhile, the experiment determines that the process of executing the consensus contract has a higher proportion of executing the target instruction than the normal process. And executing the predetermined function is performed with a relatively stable periodicity. Therefore, in this embodiment, according to the proportion feature between the number of the target objects won by the last called key instruction set and the total number of any instructions executed by the target process and the fluctuation condition of the proportion, it is determined whether the proportion of executing the target instructions by the target process is higher or not and shows stable periodicity. In turn, a quick determination is made as to whether the target process is executing a specified consensus contract (i.e., a blockchain consensus contract that employs a workload certification mechanism).
Further, the total number list NUM obtained in this embodiment does not need to distinguish between different instruction types, so that only a simple counter is used, and no great calculation effort is required.
In an exemplary embodiment of the present application, the target period is composed of p sub-periods connected in sequence and having the same length.
Meanwhile, the step S500 includes:
s510, if PL is more than Y1 and FL is less than Y2, acquiring a memory average occupancy rate list C and a video memory average occupancy rate list G corresponding to the target time period; wherein c= (C 1 ,C 2 ,…,C q ,…,C p );q=1,2,…,p;C q The average occupancy rate of the memory corresponding to the target process in the q-th sub-time period; g= (G) 1 ,G 2 ,…,G q ,…,G p );G q And the average occupancy rate of the video memory corresponding to the target process in the qth sub-time period.
S520, determining a storage occupancy feature vector CT= (CT) according to C and G 1 ,CT 2 ,…,CT q ,…,CT p );CT q =(C q ,G q );CT q Is the q-th characteristic parameter set in CT.
S530, inputting the CT into a preset K-means classification module, and if the K-means classification module does not classify the CT into any preset classification set, determining the target process as a designated consensus contract execution process; the preset classification set is determined according to a known machine learning execution process and/or a game execution process.
When the common contract related instruction is executed, the occupation characteristics of the common contract related instruction on the memory and the display memory are different from the characteristics of normal behaviors such as machine learning, encryption calculation and the like. Therefore, in this embodiment, in order to further reduce the false alarm rate, under the conditions that PL is greater than Y1 and FL is less than Y2, the average occupancy rate of the memory and the average occupancy rate of the video memory corresponding to the target process in each sub-period in the target period are further obtained, and the corresponding storage occupancy feature vector CT is established, so that the CT can include the memory occupancy feature and the video memory occupancy feature of the target process at the same time. And determining the target process as a designated consensus contract execution process when the K-means classification module does not classify the CT into any preset classification set by using a preset K-means classification module.
Because the update of the consensus contracts is faster and the differences between them are larger, if a classification set is established using the known features that execute the designated consensus contracts, and if the CT is classified into any classification set, determining the target process as the designated consensus contract executing process may result in an inability to effectively detect if the target process executes a new consensus contract. Therefore, in the application, the preset classification set is determined according to the known machine learning execution process and/or game execution process, so that the effective detection of the execution process of the new consensus contract can be effectively improved.
In an exemplary embodiment of the present application, after the step S100, the method further includes:
s110, determining a time interval list s= (S) 1 ,S 2 ,…,S j ,…,S m ) J=1, 2, …, m; m=n-1; where m is the number of time intervals, S j For the j-th time interval in S, S j =TIME j+1 -TIME j
The step S500 includes:
s501, if PL is more than Y1, FL is less than Y2 and SD is less than Y3, determining the target process as a designated consensus contract execution process; wherein SD is a duration fluctuation value, sd= (Σ) j=1 m (S j -avg (S)))/m; y3 is a preset time amount fluctuation threshold.
Experiments prove that when a process executes a consensus contract, the hash function is periodically called (the execution of the hash function can greatly execute the target instructions), and when a normal process jumps the control flow, the normal process is always random. Thus, in this embodiment, the time interval for calling the critical instruction set every two adjacent times is determined to obtain S. And obtaining a duration fluctuation value according to a plurality of time intervals in the S, and judging together with the key proportion and the proportion fluctuation value to determine whether the target process is an execution process of the appointed consensus contract, thereby identifying accuracy.
In an exemplary embodiment of the present application, before the step S100, the method further includes:
s000, in response to the CPU occupancy rate or the GPU occupancy rate being continuously larger than a preset occupancy rate threshold value within a preset duration, determining a process with the largest current CPU occupancy rate or GPU occupancy rate as a target process, and entering step S100.
In this embodiment, in order to further save the use of computing power, the above-mentioned processing steps are not required to be performed on each process in the electronic device, but only when the CPU occupancy rate or the GPU occupancy rate of the electronic device is continuously greater than the preset occupancy rate threshold value within the third set period of time, the process with the current CPU occupancy rate or the GPU occupancy rate being the largest is determined as the target process, and a specific abnormal process determination process is performed. Specifically, the third set period of time may be determined empirically, and in this embodiment, the third set period of time is 10 minutes.
