According to the technical scheme of the embodiment, the power data of the target object collected by the collection equipment is received through the platform area system, the power credit information of the target object is determined by utilizing a pre-constructed credit evaluation index system according to the power data, the power credit information is sent to the power system, the power system receives the power credit information of the target object sent by the platform area system, the power credit information is encrypted to obtain encrypted credit information and a decryption information set corresponding to the encrypted credit information, under the condition that an acquisition request of the target system for the power credit information is received, the target decryption information is selected from the decryption information set according to the acquisition request, the encrypted credit information and the target decryption information are sent to the target system, the target system decrypts the encrypted credit information by utilizing the target decryption information to obtain the decryption credit information corresponding to the power credit information, and therefore the security of sharing of the transmitted power credit information and the power credit information is improved, and the risk of sharing of the transmitted power credit information and the power credit information is reduced.

The following describes the power data sharing method based on credit evaluation provided by the present application with an application example, where the application example is exemplified by applying the method to a power system, a distribution room system and a collection device, as shown in fig. 5, the main steps include:

in a first step, a collection device collects power data of a target object (e.g., a residential user, an industrial user, a commercial user).

The acquisition equipment is an intelligent processing and reading device, can store large-capacity data, uploads the reading of an ammeter at the cloud through a network, and is directly recorded by a remote computer (a platform system), and the acquisition device stores power utilization information of corresponding users.

And secondly, the acquisition equipment performs differential coding and normalization processing on the electric power data, and prepares for data compression: differential coding, in which the original data is replaced by the difference between adjacent data, Δ = Δ ₂ -δ ₁ To show that, because the application range of the exponential Columbus coding is non-negative integer, the exponential Columbus coding is obtainedAfter the difference value is processed by normalization treatment,

，

the decimal number of which alpha is delta can be conveniently recovered after the treatment of the step, and the delta obtained after normalization _put Is a non-negative integer and is also an input for exponential golomb encoding.

Thirdly, the acquisition equipment performs data compression processing on the electric power data: according to the characteristics of exponential Golomb coding, selecting 0 order exponential Golomb coding, the coded data is in the form of Mzeros | |1| | | info |, wherein Mzeros are M0's, M = | log |) ₂ （δ _put + 1) and 1 info is delta _put The total length of the coded data is 2 _m+1 。

Fourthly, the acquisition equipment sends the compressed power data to the platform area system, and the platform area system (platform area center) decompresses the compressed power data: firstly, collecting equipment transmits Columbus codes to a security environment of a station area (station area system) for decompression, the station area reads the number of 0 of the Columbus coded data, the number is m, the number of digits of |1| | | info | is m +1, the number of digits of m +1 is continuously read, binary codes are converted into decimal codes w, and δ is obtained _put = w-1, continue on for δ _put The inverse processing before the compression is carried out,

，δ ₂ =δ ₁ +∆δ，

data redundancy is reduced by adopting a 0-order Golomb coding mode, the data transmission speed is improved, and meanwhile, the compression is lossless compression, so that the authenticity and the reliability of data are guaranteed.

Fifthly, after decompressing the compressed power data in the secure environment, the platform area calculates a credit value (power credit information): the platform district system establishes a credit evaluation index system (a credit evaluation index system of a novel user).

As shown in fig. 4, the credit evaluation index system includes credit evaluation indexes, the credit evaluation indexes mainly include two parts, which are respectively a power index of the target object itself and credit indexes of the target object transmitted by other mechanisms, the center of the platform obtains and stores basic information of the target object within its range, and divides the indexes of the target object into a first-level index and a second-level index, so as to construct an index system, wherein the power level index mainly analyzes the current and future possible power consumption conditions of the target object, and comprehensively evaluates the power consumption capability and fluctuation level, the power consumption index behavior mainly evaluates the default phenomenon and the phenomenon endangering the power consumption behavior of the target object in previous transactions, the payment behavior (payment index) is analyzed and evaluated according to the past payment resource frequency of the target object, the defaulting and defaulting bad bill behavior are evaluated according to the defaulting, bad bill and other objective frequency of the target object in previous transactions, and the third-party credit is comprehensively evaluated according to the indexes of the target object from other aspects.

Sixthly, calculating the weight of the evaluation index by the platform area system to obtain a credit value: a. determining the order relation of each index: the first-level indexes are respectively an electric quantity level index, a violation electricity utilization index, a payment index, an arrearage and bad account staying index and/or a third-party credit index, the five indexes are sorted in order relation, one index which is considered to be most important is selected from the indexes, x ^1 is selected, the most important index is selected from the rest indexes, x ^2 is selected, and the rest indexes are analogized to obtain the unique order relation x ^1 of the five indexes>x^2>…>x ^5; b. determining the weight evaluation scale of the adjacent indexes: in the step, the importance degree of the index weight is quantified and is embodied in a ratio form: r is a radical of hydrogen _k =w ^k /w ^k-1 (k =2,3,4,5), r obtained _k Are not all the same, r _k The larger the value of (c), the more important the weight representing the kth index; c. calculating the weight w _k : by obtaining r _k The rational assignment of (2) is carried out, the weight of the corresponding index is calculated, and then the kth index isThe weight of the index is calculated as

，

w _k'-1 =r _k ∙w _k' (k =2,3,4,5), the weight of the index to be evaluated is obtained through the above steps, and when the evaluation is performed, the weight of the index is the corresponding combination thereof, and the weight coefficient of the l-th object is set to dl, wherein 0<d _l <1，

，

The weight of the kth index can be expressed as

，

Determining the weight value of the secondary indexes by using the conflict between the indexes and the information quantity, wherein the higher the correlation coefficient between the two indexes is, the smaller the representative conflict is, the larger the standard deviation of a single index is, and the larger the information quantity contained in the single index is, a, firstly, normalizing each index by adopting a deviation standardization method to ensure that measurement units are uniform and obey statistical probability distribution between 0 and 1, and b, determining the conflict T between the indexes _ij And the information amount C of the individual index _j Is shown as

，

，

In the formula r _ij Is the correlation coefficient between indices i and j, δ _j Is the standard deviation of the jth index, n is the number of evaluations, C _j The larger the index is, the greater the importance of the index is, and the weight coefficient of the c

，

In the formula w _ij The weight coefficient of the jth secondary index under the ith primary index is respectively obtained through the steps to calculate the credit value of each target object, and the credit value of each target object is

，

Wherein w ₁ To w ₅ Weight, w, representing each level of power index ₁₁ To w ₅₄ Weight, Q, representing each secondary power indicator ₁₁ To Q ₅₄ Representing each secondary power information, different types of target objects (such as industrial users and commercial users) can construct corresponding calculation modes according to different index characteristics of the target objects.

Seventhly, the electric power system acquires information and interacts with other mechanisms: the power system performs identity authentication on the platform center, the two ends have the same group of passwords, the identity of the platform center is judged by verifying whether the passwords are consistent, after the platform center obtains the credit value of the corresponding target object (residential user, commercial user and industrial user) through calculation, the credit value is transmitted to the power system center, the power system center also adopts a trustzone architecture to protect the privacy information of the target object, and meanwhile, the electricity utilization credit value of the target object is calculated in the platform area, so that the calculation pressure of the power system center is reduced. After the electric power system obtains the credit value of each target object, the credit value is transmitted to a third party organization (target system), the risk of the organization is reduced through credit sharing, only when the number of departments needing the credit value of the target object in the target system is larger than a certain specified value, the electric power system transmits the credit value of the target object to the organization (target system), in order to ensure the confidentiality and the integrity of data in the transmission process, the electric power system adopts a (t, w) (t is less than or equal to w) threshold secret sharing scheme to the third party organization, the electric power system calculates the credit value of the target object, divides the credit value into w secret fragments, and divides t or more secret fragments intoAnd (3) transmitting the t secret shards to a third-party organization (target system) meeting the condition, thereby realizing that only a specific organization can restore the credit value of the target object, and other organizations cannot decrypt the credit value without enough secret shards, wherein the basic flow is as follows: step one, a power system generates secret fragments: f (x) = S + a ₁ *x ¹ +a ₂ *x ² +⋯+a _t-1 *x ^t-1 mod (P), where S is the credit value of the target object, P is a prime number, and S is satisfied<P, taking W unequal x, substituting into the polynomial to obtain W groups (x, y) _i ) Wherein y is _i For F (x), randomly selecting t secret fragments from the F (x) to distribute to a target object, disclosing P, and destroying the polynomial; step two, secret recovery in the third party field:

，

wherein the negative first power is the inverse of the term modulo p, and t groups of secret shards (x, y) _i ) The credit value S of the target object can be obtained by substitution, and in addition, parameters or symbols which are not explained in all the formulas can be set with numerical values according to needs.

Specifically, as shown in fig. 5, the collection device acquires electricity consumption data, performs data compression processing, transmits (transmits) the data to the platform area center (platform area system), the platform area center decompresses the data, calculates a credit value, the power system center (power system) performs identity authentication to determine whether the identity authentication passes, if not, the collection device transmits the data to the power system center, the power system center divides the credit value into a plurality of secret fragments, transmits a certain number of secret fragments to a third party organization (target system), and the third party organization decodes the secret fragments to obtain the credit value.
