[0039] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0040] In one embodiment, as Figure 1 shown, Figure 1 is a schematic flowchart of a data sharing method for a power system provided by an embodiment of the present application; the present application provides a data sharing method for a power system, and the method may include:

[0041] S110: When it is detected that the data owner shares data with the target user, obtain the first random number selected by the target user and the corresponding encryption sequence.

[0042] In this step, when the power system detects that the data owner, that is, the grid client, shares data with the target user, the system can obtain the first random number selected by the target user and the corresponding encryption sequence. The encryption sequence is pre-generated by the system in combination with the first random number selected by the target user, the multiplicative cyclic group tuple of prime order generated during system initialization, and the hash function. Therefore, when it is detected that the data owner shares data with the target user, the pre-generated encryption sequence can be directly obtained, thus saving data encryption time.

[0043] It can be understood that when the power system of the present application is initialized, a multiplicative cyclic group tuple of prime order can be generated , where is a multiplicative cyclic group of prime order , and is a generator of the group . Then, the power system can select hash functions , and , represents mapping any binary to -dimensional vector, and the value range is . In this way, after receiving the first random number selected by the target user, the corresponding encryption sequence can be generated.

[0044] S120: Obtain the message to be encrypted input by the data owner and the second random number, calculate the encrypted hash according to the current count value of the counter, the first random number, and the second random number, encrypt the message to be encrypted according to the hash function, the encrypted hash, and the encryption sequence, and send the encrypted ciphertext to the cloud server for storage.

[0045] In this step, after obtaining the first random number selected by the target user and the encryption sequence pre-generated by the system through S110, the present application can also obtain the message to be encrypted input by the data owner and the second random number. Thus, after calculating the encrypted hash based on the current count value of the counter, the first random number, and the second random number, the message to be encrypted can be encrypted according to the hash function, the encrypted hash, and the encryption sequence. The entire process uses multiplication operations, and the encryption speed is dozens of times that of the conventional solution, thereby greatly improving the encryption efficiency. Moreover, after encrypting the information to be encrypted, the present application can also send the encrypted ciphertext to the cloud server for storage. In this way, both the target user and the data owner can download the ciphertext from the cloud server and decrypt it according to their needs.

[0046] S130: Generate a shared key corresponding to the encrypted hash, and send the shared key to the target user, so that after the target user downloads the ciphertext from the cloud server, the ciphertext can be decrypted according to the shared key.

[0047] In this step, after encrypting the information to be encrypted sent by the data owner through S120 and uploading it to the cloud server, the present application can also generate a shared key corresponding to the encrypted hash and send it to the target user. In this way, it can not only ensure the security of the encrypted hash, but also enable the target user to decrypt the ciphertext according to the encrypted hash in the shared key after downloading the ciphertext from the cloud server, so as to achieve data sharing.

[0048] For example, when the target user downloads the ciphertext from the cloud server, the encrypted hash can be obtained first through the following formula:

[0049]

[0050] In the formula, is the encrypted hash, and are the shared keys, is the first random number selected by the target user.

[0051] Then, the present application can also calculate the decrypted ciphertext through the following formula:

[0052]

[0053]

[0054] Among them, is the mapping vector, M is the decrypted ciphertext, is the ciphertext, .

[0055] In the above embodiments, when it is detected that the data owner shares data with the target user, the first random number selected by the target user and the corresponding encryption sequence can be obtained. The encryption sequence is generated based on the first random number, the multiplicative cyclic group tuple of prime order generated during the initialization of the system, and the hash function. Then, the message to be encrypted input by the data owner and the second random number are obtained. In this way, after calculating the encrypted hash according to the current count value of the counter, the first random number, and the second random number, the message to be encrypted can be encrypted according to the hash function, the encrypted hash, and the encryption sequence, and the encrypted ciphertext is sent to the cloud server for storage. After that, a shared key corresponding to the encrypted hash is generated, and the shared key can be sent to the target user. In this way, after the target user downloads the ciphertext from the cloud server, the ciphertext can be decrypted according to the shared key. This process converts the traditional power operation into a multiplication operation, and the encryption speed is dozens of times that of the conventional solution, thus greatly improving the encryption efficiency. Moreover, in this application, only the encrypted hash needs to be shared between the data owner and the target user to achieve efficient data sharing, and good performance can be achieved even in the case of a large amount of data.

[0056] In one embodiment, as Figure 2 shown, Figure 2 is a schematic flowchart of a method for revoking data sharing for a power system provided by an embodiment of this application; the method may further include:

[0058] In this embodiment, after this application encrypts the information to be encrypted according to the above encryption method, if the data owner wants to revoke the data sharing with the target user, the system only needs to update the current count value of the counter, recalculate the encrypted hash based on the updated count value, and then update the ciphertext stored in the cloud server according to the recalculated encrypted hash, without downloading the entire data set for local update, thereby reducing the broadband cost while achieving efficient update of the ciphertext.

[0059] In one embodiment, the method may further include:

[0060] S150: When it is detected that the data owner decrypts the ciphertext, decrypt the ciphertext according to the encrypted hash.

[0061] In this embodiment, the data owner can also download the ciphertext from the cloud server. When the system detects that the data owner downloads the key and decrypts it, the ciphertext can be decrypted according to the pre-saved encrypted hash.

[0062] For example, the data owner in this application inputs the ciphertext that needs to be decrypted , and then through the following calculation formula, the ciphertext can be decrypted. The specific formula is as follows:

[0068] S220: Determine the random vector according to the first random number and the hash function, and generate the encryption sequence based on the random vector, the prime order, and the generator in the multiplicative cyclic group tuple.

[0069] In this embodiment, when generating the encryption sequence, this application can first obtain the multiplicative cyclic group tuple of prime order and the hash function generated after the initialization of the system, as well as the first random number selected by the target user, then determine the random vector according to the first random number and the hash function, and then generate the encryption sequence based on the random vector, the prime order, and the generator in the multiplicative cyclic group tuple.

[0070] In a specific implementation manner, the first random number selected by the target user in this application is , let the private key , calculate the public key , the random vector is , and then the formula for calculating the encryption sequence is as follows:

[0071]

[0072] Among them, , . Obtain the encryption sequence .

[0074] S121: Determine a mapping vector according to the hash function and the encrypted hash.

[0075] S122: Encrypt the message to be encrypted according to the encryption sequence and the mapping vector.

[0076] In this embodiment, when encrypting the message to be encrypted according to the hash function, the encrypted hash, and the encryption sequence, a mapping vector may be determined first according to the hash function and the encrypted hash, and then the message to be encrypted may be encrypted according to the encryption sequence and the mapping vector.

[0077] For example, when the data owner inputs the message to be encrypted and the encryption sequence after that, a second random number and an initialized counter are selected, and the following is calculated:

[0078]

[0079]

[0080] wherein, is the encrypted hash, is the mapping vector. The ciphertext is sent to the CSP for storage. Among them, and are the ciphertexts obtained after encrypting the message to be encrypted, and the of this application can be linked to each other, so there is no need for repeated storage.

[0081] In one embodiment, generating a shared key corresponding to the encrypted hash in S130 may include:

[0082] S131: Obtain the generator in the multiplicative cyclic group tuple of prime order generated after the initialization of this system.

[0083] S132: Determine a private key according to the first random number, and calculate a public key according to the generator and the first random number.

[0084] S133: Generate a shared key according to the encrypted hash, the public key, and the private key.

[0085] In this embodiment, when generating a shared key corresponding to an encrypted hash, the generator in the multiplicative cyclic group tuple of prime order generated after the initialization of the system can be obtained first, then the private key is determined according to the first random number, and the public key is calculated according to the generator and the first random number. Then, according to the encrypted hash, the public key and the private key, a shared key is generated. Among them, the process of determining the private key according to the first random number and calculating the public key according to the generator and the first random number in this application can refer to the above calculation process and will not be elaborated here. After obtaining the private key and the public key in this application, the process of generating the shared key is as follows:
