Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method for acquiring the power block provided by the application can be applied to the application environment shown in fig. 1. The power system server 101 is connected to the power mechanism nodes 102 and 103 via a network, and the connection may be wired or wireless. In the application scenario shown in fig. 1, the number of the power mechanism nodes in the present scheme includes at least two, and the power system server 101 may select one of the power blocks generated by the power mechanism nodes 102 or 103 as a power block connected to a power system block chain.
In an embodiment, as shown in fig. 2, a method for acquiring a power block is provided, which is described by taking the method as an example applied to the power system server 101 in fig. 1, and includes the following steps:
step S201, the power system server 101 obtains mechanism level identifiers of a plurality of power mechanism nodes of a power system block chain; the authority level identification is used to identify the authority level of the power authority node.
When an electric power mechanism joins the electric power mechanism node network, the electric power system server 101 may identify the identity of the newly joined electric power mechanism node in advance, so as to obtain node information of the electric power mechanism node and the mechanism level of the electric power mechanism node, and store the mechanism level as a mechanism level identifier. The levels of the power mechanism nodes may include provincial level, regional level, county level, township level, and the like, and may be recorded as mechanism level identifiers by using digital identifiers, for example: provincial electric power mechanism can be marked as 1, regional electric power mechanism can be marked as 2, county electric power mechanism can be marked as 3 and county electric power mechanism can be marked as 4 etc. when electric power system server 101 needs to obtain the electric power block, the mechanism level sign that can follow a plurality of electric power mechanism nodes that prestore draws out for the mechanism level of sign electric power mechanism node.
Step S202, the power system server 101 takes a power mechanism node with the same mechanism level identification as the preset mechanism level identification as a committee node in the plurality of power mechanism nodes; the number of committee nodes is plural.
After the electric power system server 101 obtains the mechanism level identifiers of the plurality of electric power mechanism nodes, the electric power mechanism nodes satisfying the predetermined level identifiers can be selected as committee nodes according to the identifiers, for example: if it is desired to select provincial power agencies as committee nodes, the power system server 101 may select a power agency node with an agency level identification of 1, such as the power agency node 102 or the power agency node 103, as a committee node, where the number of committee nodes may be plural.
In step S203, the power system server 101 acquires a plurality of power blocks generated by a plurality of committee nodes, respectively.
Each committee node in the power system block chain may be a resolver for generating a power block, one of the proposals is selected as an embodiment of a generation block from among the proposals for generating the power blocks, and the power block corresponding to each committee node is generated according to the proposal, and since the number of the committee nodes is plural, the generated power blocks may be plural, and the power system server 101 may store the corresponding relationship between the committee nodes and the power blocks generated by the committee nodes.
Step S204, the power system server 101 determines a plurality of node trust values respectively corresponding to a plurality of committee nodes;
in step S205, the power system server 101 selects, from the plurality of power blocks, a power block generated by the committee node corresponding to the maximum node trust value among the plurality of node trust values as a power block connected to the power system block chain.
In the above steps S204 and S205, the node trust value may be relatively determined by the power system server 101, and is used to represent the credibility of the committee nodes, each committee node has a respective corresponding node trust value, and the power system server 101 may select, from a plurality of different node trust values corresponding to different committee nodes, the power block generated by the committee node with the largest node trust value as the power block finally connected to the power system block chain. For example, the power authority node 102 and the power authority node 103 are two different committee nodes, respectively, where the power authority node 102 generates the power block a, the power authority node 103 generates the power block B, and the node trust value of the power authority node 102 is greater than the node trust value of the power authority node 103, then the power system server 101 selects the power block a as the power block connected to the power system block chain.
In the method for acquiring the power block, mechanism level identifiers of a plurality of power mechanism nodes of a power system block chain are acquired; the mechanism level identification is used for identifying the mechanism level of the power mechanism node; taking the power mechanism node with the mechanism level identification being the same as the preset mechanism level identification in the plurality of power mechanism nodes as a committee node; the number of committee nodes is multiple; obtaining a plurality of power blocks generated by a plurality of committee nodes respectively; determining a plurality of node trust values corresponding respectively to a plurality of committee nodes; and selecting the power block generated by the committee node corresponding to the maximum node trust value in the node trust values from the power blocks as the power block connected to the power system block chain. According to the method and the device, the committee node with the largest node trust value is selected as the node for generating the block, and the block is generated by utilizing the node, so that the technical problem that the common recognition mechanism used in the block chain technology of the power system in the traditional technology has large calculation loss can be solved, and further the calculation loss of the power system is reduced.
In one embodiment, as shown in fig. 3, step S203 may include:
step S301, the power system server 101 acquires a plurality of proposed blocks of committee nodes; wherein the proposed block is generated by a plurality of power agency nodes belonging to the committee node.
Since the committee node selected in step S202 is generally a power mechanism node with a higher mechanism level, for example, a provincial power mechanism node may be selected as the committee node, different power mechanisms in the power system may be divided according to different provinces at this time, and a lower power mechanism node having the same province as the provincial power mechanism node, such as a local power mechanism or a county power mechanism of the same provincial, may be selected as the power mechanism node belonging to the committee node. Since the number of committee nodes is plural and the number of power agency nodes belonging to a certain committee node is also plural, the number of proposed blocks to be generated may be plural.
Step S302, the committee node acquires a seed random number of the committee node;
in step S303, the committee node generates, based on the seed random number, a plurality of random numbers respectively corresponding to the plurality of power mechanism nodes belonging to the committee node by using the pseudo random number generator.
The seed random number is acquired by a committee node, and after the committee node acquires the seed random number, the acquired seed random number can be used as a seed of a pseudo-random number generator to generate a random number for each power mechanism node belonging to the committee node.
Step S304, based on a plurality of random numbers, the committee nodes sort a plurality of power mechanism nodes belonging to the committee nodes to obtain node sorting results;
step S305, the committee node acquires a target proposed block matched with the node sorting result from the plurality of proposed blocks;
in step S306, the power system server 101 obtains a plurality of power blocks generated by the plurality of committee nodes, respectively, based on the power blocks of the target proposed block committee node generation committee node.
After the committee node generates a random number for each power agency node belonging to the committee node, each obtained random number may be calculated by using a permutation function, so as to obtain a ranking level of each power agency node belonging to the committee node, so as to obtain a power node ranking result, according to the ranking result, one proposed block is selected from a plurality of proposed blocks as a target proposed block, and a power block is generated based on the target proposed block as a power block of the committee node, and the power system server 101 may store the power blocks generated by the plurality of committee nodes, so as to select the power block generated by the committee node with the largest node trust value as the power block finally connected to the power system block chain.
For example: committee node a may have utility nodes a1, a2, A3 belonging to committee node a, and utility nodes a1, a2, and A3 generate proposed blocks a10, a20, and a30, respectively, committee node a may assign random numbers to utility nodes a1, a2, and A3, respectively, according to the obtained seed random numbers as pseudo-random number generators, and calculate the random numbers assigned to utility nodes a1, a2, and A3, respectively, using a permutation function, thereby obtaining ranking results of utility nodes a1, a2, and A3, which may be a2, a1, and A3, and then may select proposed block a20 generated by utility node a2 as a target proposed block according to the ranking results, and generate a power block of utility node a based on proposed block a 20.
In this embodiment, the committee node may set random numbers for a plurality of power mechanism nodes belonging to the committee node according to the seed random number, and then determine the target proposed block by using the random numbers to generate a corresponding power block, thereby improving the decentralized level of the power block generation process and improving the security of the power system data.
Further, as shown in fig. 4, the step S302 may further include:
step S401, signature information of the committee node on the power node information is obtained by the committee node, and a plurality of signature information respectively corresponding to a plurality of committee nodes is obtained; the power node information is node information of committee nodes;
the signature information of the power node information can be obtained through a threshold signature algorithm, and the committee node can process the power node information of the committee node, so that the signature information of the committee node is obtained.
In step S402, the committee node acquires group signature information according to the plurality of signature information.
After all committee nodes obtain the self signature information, the self signature information can be transmitted to other committee nodes in a sharing mode, and each committee node can process the obtained signature information of other committee nodes and the self signature information to obtain the group signature information.
In step S403, the committee node acquires a seed random number of the committee node according to the group signature information.
After the committee node obtains the group signature information, the group signature information can be used as a verifiable random function, and the seed random number of the committee node is obtained by utilizing Hash operation.
Further, step S403 may include: generating a random number to be verified by the committee node according to the group signature information; carrying out validity verification on the random number to be verified to obtain a verification result of the validity verification; if the verification result of the validity verification is legal, the random number to be verified is used as the seed random number of the committee node; if the result of the validity verification is illegal, the proposed block is discarded.
Specifically, after the group signature information is obtained in step S402, the hash operation is first applied to obtain the random number to be verified according to the group signature information, then the validity verification is performed on the random number to be verified, only when the result of the validity verification is that the random number is valid, the random number to be verified is used as the seed random number of the committee node, and if the result of the validity verification is that the random number is not valid, the proposed block proposed by the committee node is discarded.
In addition, step S401 may further include: the committee node acquires seed random numbers used when other committee nodes generate corresponding power blocks; signature information of the committee nodes on the power node information is acquired based on seed random numbers used when other committee nodes generate corresponding power blocks.
Since the committee node repeats all the processes from step S301 to step S306 every time it generates a new block, a corresponding seed random number is generated in the process of generating each block by each committee node, while the committee node forms signature information according to its own information, the seed random number obtained in the process of generating blocks by other nodes can be used as a part of the input source of the signature information to sign the signature information, and in the subsequent validity verification process, it can also be determined whether other block information is introduced into the block information, and if no other block information is introduced, the validity verification result can be determined to be illegal.
In the embodiment, the signature information of the committee node is obtained from the power node information of the committee node through the threshold signature algorithm, the group signature information is formed from the signature information of the committee nodes generated by the power node information of other committee nodes, and then the random number is generated according to the group signature information, so that the random number is generated by a plurality of nodes, and the safety of random number generation is improved. In addition, the random number is further subjected to validity verification, only the random number passing the validity verification can be used as a seed random number to participate in the power block generation process, the obtained seed random number can also be further used as a part of signature information input in the next power block generation process, whether the block refers to the information generated by the previous block or not can also be judged in the validity verification process, and the safety of random number generation is further ensured.
In one embodiment, step S204 may further include: the power system server 101 determines a plurality of power agency nodes belonging to the committee node; obtaining a plurality of sub-trust values corresponding to a plurality of electric power agency nodes belonging to a committee node; and obtaining the node trust values corresponding to the committee nodes according to the plurality of sub trust values to obtain a plurality of node trust values respectively corresponding to the plurality of committee nodes.
Specifically, the electric power system server 101 may determine a plurality of electric power organization nodes belonging to a certain committee node and a plurality of sub-trust values corresponding to the plurality of electric power organization nodes, and sum the plurality of sub-trust values based on the plurality of sub-trust values to obtain the node trust value of the committee node.
Further, a plurality of mechanism weights corresponding to a plurality of electric power mechanism nodes belonging to the committee node can be obtained based on a preset weight corresponding table, wherein the corresponding relation between the mechanism level identification and the mechanism weight is stored in the weight corresponding table; and based on the plurality of mechanism weights, carrying out weighted summation processing on the plurality of sub-trust values to obtain the node trust value corresponding to the committee node.
Specifically, for example, the committee nodes include 2 ground-level electric power organization nodes B1 and B2, and 1 county-level electric power organization node C1, the sub trust value of B1 is 5, the sub trust value of B2 is 6, the sub trust value of C1 is 5, the organization weight value corresponding to the ground-level electric power organization node is 4, and the organization weight value corresponding to the county-level electric power organization node is 3, so that the node trust value of the committee node is 59 at this time.
According to the embodiment, the node trust values of the committee nodes are calculated by setting the trust values of different power mechanism nodes, the power block generated by the largest committee node in the node trust values can be selected more scientifically, meanwhile, the power mechanism with the larger mechanism level can have a higher weight value by setting the mechanism weight value, the scientificity of the trust value calculation process can be further improved, and the power block connected to the power system block chain can be selected more accurately.

The method for acquiring the power block provided by the embodiment reduces the calculation loss of the power system and improves the safety of the power system.
The following method for acquiring power blocks is described by way of an application example, and with reference to fig. 6, may include the following steps:
And step 2, initializing the power data block. And running a distributed key generation algorithm at each provincial electric power mechanism to generate a public-private key pair and a provincial-level general verification key of each node member. First, a random number is acquired. Running an (m, n) -threshold signature algorithm at the provincial power agency, wherein m is a threshold; n is the member number of provincial power mechanisms, and n is 3m + 1. The provincial power agency uses the last round of random numbers as messages and generates threshold signatures. And if any power agency node receives m valid signatures, reconstructing and recovering the total signature. The adopted threshold signature algorithm comprises the following steps:
2.1, divide n into members of provincial electric power institutions
Group (d);
2.2, selecting a modulus N, wherein N is pq, p is 3p '+ 1, and q is 3 q' +1, wherein p, q, p 'and q' are prime numbers;
2.3, randomly selecting m pairs of different numbers as keys of m power mechanisms, generating a polynomial by adopting an interpolation theorem, and using a common key k1 of the signature group;
2.4, randomly selecting m pairs of different numbers to construct another polynomial, and respectively using the polynomial as public keys k2 corresponding to the signature groups; and the steps are circularly carried out until n public keys kn are obtained;
2.5, obtaining a group key K-K1-K2- … kn mod f (n), wherein f (n) and constant terms of the polynomial are prime numbers;
and 2.6, finally generating a threshold signature according to the group key and the member information of the power node.
And step 3, generating a power data block. And selecting a higher node as an initial node committee according to the node level information of the power mechanism, and generating a random number for each power mechanism node by taking the random number generated in the current round as a seed of a pseudo-random number generator. And calculating the random number by adopting a permutation function to obtain the sequencing level of each node in the power mechanism. The proposal generated by the elected block is then sorted according to node.
And 4, confirming the power data blocks, calculating trust values R of all power mechanism nodes according to the proposed blocks generated in the step 4, respectively giving different weights a, B, C and D to a provincial power mechanism node A, a regional power mechanism node B, a county power mechanism node C and a rural power mechanism node D according to different power mechanism nodes, then calculating the trust value R as ∑ (a is Ai + B Bi + C Ci + D Di), and selecting the block with the maximum trust value as the final power data block.
