Abstract
Description
Technical Field
[0001] The present invention relates to the field of information security technology, and in particular to a method and system for managing power material sampling information based on hybrid encryption technology. Background Art
[0002] With the advent of the information age, data security has become the focus of attention in all walks of life. Especially in the power industry, as one of the country's key infrastructure, the security of its material management information is directly related to the country's energy security and the stability of economic operation. Traditional methods of power material sampling information management mostly rely on simple identification technology, such as scanning the QR code or barcode associated with the material to link to the relevant website to obtain the material information. Although these methods facilitate the rapid reading of information to a certain extent, they also have many security risks.
[0003] First, the material sampling information obtained by traditional identification technology is usually in plain text, which is easily obtained by unauthorized third parties, resulting in the leakage of sensitive information. Criminals may use this information to conduct commercial espionage or other malicious activities, posing a serious threat to the business secrets and market competitiveness of enterprises.
[0004] Secondly, with the continuous evolution of network attack methods, traditional information management methods can hardly effectively resist complex network attacks, such as SQL injection, cross-site scripting attacks, etc. These attacks may cause the permissions of the material management system to be bypassed or the information to be tampered with.
[0005] Thirdly, the existing material sampling information management system also has deficiencies in authority control. Simple role division and authority management methods cannot meet the needs of refined access control for users at different levels and with different roles, leading to the risk of authority abuse and information leakage.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.
[0027] The present invention provides a method for managing power material sampling information based on hybrid encryption technology. In a preferred embodiment, the method includes:
[0028] In step S1, the power grid end pre-processes the power material sampling information to obtain material sampling data, divides the material sampling data into multiple sampling subsets corresponding to multiple access rights, generates multiple RSA key pairs corresponding to multiple access rights, an RSA key pair includes an RSA private key and an RSA public key, uses the RSA public key corresponding to each access right to encrypt the sampling subset corresponding to the access right to obtain RSA ciphertext, and sends the RSA ciphertext and RSA private key to the data server.
[0029] The sampling inspection information of electric power materials includes multi-dimensional information such as the manufacturer information, supplier information, production date, batch number, quality inspection results, etc. of the electric power materials. Set multiple access rights with different authority levels, and each access right corresponds to different sampling inspection information of electric power materials. Specifically, each access right corresponds to the sampling inspection information of different electric power materials, or each access right corresponds to information of different dimensions of electric power materials. Therefore, each access right corresponds to a sampling inspection subset and a pair of RSA key pairs. The RSA key pair corresponding to each access right is used to encrypt the sampling inspection subset corresponding to the access right to obtain the RSA ciphertext, thus obtaining multiple RSA ciphertexts. The RSA algorithm is an existing asymmetric encryption algorithm that uses the mathematical problem that the product of two large prime numbers is difficult to decompose to achieve security, so the RSA key pair generation process will not be repeated here.
[0030] The RSA algorithm utilizes the asymmetric characteristics of the RSA algorithm, that is, after the data is encrypted with the public key, it can only be decrypted using the corresponding private key. This ensures the confidentiality of the data during transmission. Even if the data is intercepted during transmission, the data content cannot be deciphered without the correct RSA private key.
[0031] Step S2: The data server encrypts the RSA private key based on the CP-ABE encryption system to obtain the RSA private key ciphertext.
[0032] Specifically, the data server receives multiple RSA ciphertexts and multiple RSA private keys, and the multiple RSA ciphertexts correspond to the multiple RSA private keys one by one. The data server encrypts the multiple RSA private keys based on the CP-ABE encryption system to obtain multiple RSA private key ciphertexts, and there is an associated correspondence between the RSA private key ciphertext, the RSA ciphertext and the access rights.
[0033] Step S3: The user device sends an information access request to the data server, and the information access request includes a user attribute set. The user attribute set includes the user's name and security clearance level. The security clearance level includes a low security clearance level, a medium security clearance level, and a high security clearance level.
[0034] Step S4: The data server decrypts the RSA private key ciphertext using the decryption algorithm of the CP-ABE encryption system based on the user's attribute set to obtain the RSA private key, and sends the obtained RSA private key and the RSA ciphertext corresponding to the obtained RSA private key to the user device. According to the associated correspondence between the RSA private key, the RSA public key and the RSA ciphertext, the corresponding RSA ciphertext is obtained.
[0035] Step S5: The user device decrypts the received RSA ciphertext using the received RSA private key, and obtains the material sampling information corresponding to the user access rights based on the decryption result.
[0036] In a preferred implementation, in step S1, after the grid end uses the RSA public key corresponding to each access right to encrypt the sampling subset corresponding to each access right to obtain the RSA ciphertext, it further performs:
[0037] The RSA ciphertext is padded using the optimal asymmetric encryption padding algorithm (OAEP algorithm), and the padded RSA ciphertext is sent to the data server. The padding process can enhance the security of the encryption process and prevent potential cryptanalysis attacks.
[0038] In a preferred embodiment, in step S1, after the grid end encrypts the sampling subset corresponding to each access right by using the RSA public key corresponding to each access right to obtain the RSA ciphertext, the following further comprises:
[0039] The RSA private key corresponding to each access right is used to sign the sampling subset corresponding to the access right to obtain a digital signature, and the digital signature is sent to the data server.
[0040] Preferably, in step S4, after the data server decrypts the RSA private key ciphertext using the decryption algorithm of the CP-ABE encryption system based on the user's attribute set to obtain the RSA private key, it also sends the digital signature to the user device; after the user device obtains the material sampling information corresponding to the user's access rights, it verifies the digital signature using the RSA public key. This ensures that the data has not been tampered with.
[0041] In a preferred embodiment, in step S1, the power grid end pre-processes the power material sampling information to obtain material sampling data, including:
[0042] Step a: Standardize the power material sampling information to obtain standardized processing results to ensure the smoothness and efficiency of subsequent processing steps.
[0043] Step b, serializing the standardization processing result to obtain serialized data, so as to facilitate efficient transmission and storage of data, preferably but not limited to selecting JSON (JavaScript Object Notation) as the serialization format.
[0044] Step c: compress the serialized data to obtain the material sampling data. Compress the data using the corresponding Java class and method to generate a compressed data stream or file. The compressed data can significantly reduce the storage space requirements and speed up the network transmission speed, while ensuring the integrity and recoverability of the data.
[0045] In this embodiment, it is further preferred that in step a, the power material sampling information is subjected to standardization processing to obtain a standardized processing result, including:
[0046] The power material sampling information includes multiple dimensional information of multiple power materials, such as manufacturer information, supplier information, production date, batch number, quality inspection results, etc. Each dimensional information of each power material is converted into a key-value pair, where the key of the key-value pair represents the dimension name, the value of the key-value pair represents the dimension value, and multiple key-value pairs of multiple power materials constitute the standardized processing results. Multi-dimensional information is converted into a unified key-value pair format, which helps to improve the efficiency of subsequent processing. For example, "manufacturer" can be used as the key and the corresponding manufacturer name as the value.
[0047] In a preferred embodiment, in step S2, the data server encrypts the RSA private key based on the CP-ABE encryption system to obtain the RSA private key ciphertext, including:
[0048] Define the access structure of the CP-ABE encryption system; the access structure includes multiple policies for representing the correspondence between user attribute sets and access rights. Each policy represents a user attribute set and an access right. In this way, the correspondence between the user attribute set and the RSA ciphertext and the RSA private key ciphertext can be obtained according to the access structure. For example, a policy may require that a user must have both the "Material Management Department" and "Advanced Security Permission" attributes to access the RSA ciphertext corresponding to a certain access right.
[0049] Get security parameters and input them into the initialization algorithm ABE.Setup(·) of the CP-ABE encryption system to obtain the ABE public key PK ABE and ABE master key MK ABE Specifically, let the security parameter be λ, then:
[0050] ABE.Setup(1 λ )→PK ABE ,MK ABE .
[0051] Input the access structure, ABE public key and RSA private key into the encryption algorithm ABE.Encrpt(,,) of the CP-ABE encryption system to obtain the RSA private key ciphertext CT ABE . T represents the access structure.
[0052] ABE.Encrpt(PK ABE ,RSA private key,T)→CT ABE .
[0053] In a preferred embodiment, in step S4, the data server decrypts the RSA private key ciphertext using the decryption algorithm of the CP-ABE encryption system based on the user's attribute set to obtain the RSA private key, including:
[0054] Input the user's attribute set and ABE master key into the private key generation algorithm ABE.KeyGeneration(,) of the CP-ABE encryption system to obtain the user's ABE private key. Suppose the attribute set of user i is S i , then user i's user ABE private key SK ABE,i for:
[0055] ABE.Key Generation(MK ABE ,S i )→SK ABE,i .
[0056] Input the ABE public key, RSA private key ciphertext and user ABE private key into the decryption algorithm of the CP-ABE encryption system to obtain the RSA private key. The RSA private key of user i is SK RSA,i :
[0057] ABE.Decrpt(PK ABE ,CT ABE ,SK ABE,i )→SK RSA,i .
[0058] Specifically, the ABE public key and the user's ABE private key can be used together with each RSA private key ciphertext to input the above decryption algorithm formula. If the decryption is successful, the RSA private key of user i is obtained. If the decryption is unsuccessful, the ABE public key and the user's ABE private key are used together with the next RSA private key ciphertext to input the above decryption algorithm formula to solve it until the RSA private key of user i is obtained.
[0059] In this implementation, CP-ABE technology is used to encrypt the critical RSA private key. Through carefully defined access policies, it is ensured that only users with corresponding attributes and who meet specific conditions can obtain access rights to the RSA private key, thereby achieving secure control over the ability to decrypt sensitive data. This is a flexible and efficient permission management mechanism.
[0060] In a preferred embodiment, in step S5, the user uses the received RSA private key to decrypt the received RSA ciphertext, and obtains the material sampling information corresponding to the user access rights based on the decryption result, including:
[0061] The user uses the received RSA private key to decrypt the received RSA ciphertext to obtain the material sampling data corresponding to the user's access rights and restore the original data;
[0062] Decompress the material sampling data corresponding to the user's access rights to obtain decompressed data;
[0063] Deserialize the decompressed data to obtain the material sampling information corresponding to the user's access rights.
[0064] The above-mentioned electric power material sampling information management method based on hybrid encryption technology disclosed in the present invention realizes the comprehensive protection of material sampling information in the power industry. First, the material sampling information is preprocessed and serialized into an easy-to-process JSON format, and then an efficient compression algorithm is applied to reduce the data volume. Next, the compressed data is encrypted end-to-end using the RSA algorithm to ensure the security of the data at any stage. In addition, by defining the CP-ABE encryption policy access structure and attribute set, fine-grained access control based on user attributes is realized, and only authorized users who meet the policy can decrypt the data.
