It should be noted that, under the premise of no conflict, the various embodiments described below or the various technical features can be arbitrarily combined to form a new embodiment.

It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.
[0027] Below, some terms in this application are explained to facilitate understanding by those skilled in the art.
[0028] CKKS (Cheon-Kim-Kim-Song) is an encryption scheme based on partially homomorphic encryption that can support addition and multiplication operations on encrypted data while maintaining the encryption state of the data. The CKKS scheme is particularly suitable for processing real and complex data, and can perform calculations while protecting data privacy.
[0029] Wails is a modern cross-platform desktop application development framework built on the Go language. It allows developers to use familiar front-end technologies (such as HTML, CSS, JavaScript) to create user interfaces. Combined with the logical processing capabilities of the Go backend, developers can quickly build lightweight and efficient desktop applications while keeping the code concise and easy to maintain.
[0030] The following will first explain the homomorphic encryption desktop application system, and then explain its application methods.
[0031] System Embodiments.
[0032] See also Figure 1 , Figure 1 This is a system block diagram of a homomorphic encryption desktop application system provided in an embodiment of the present application.
[0033] This embodiment provides a homomorphic encryption desktop application system for encrypted data calculation, and the system includes: An interactive layer, which is used to provide an interactive interface for operators. The interactive interface includes a plurality of interactive buttons. Each of the interactive buttons is used to set key generation, key calculation, encryption, decryption and calculation as the operator's target action after being clicked, and call the application layer function corresponding to the target action through the Wails framework; An application layer, the application layer comprising a CKKS homomorphic encryption module, the CKKS homomorphic encryption module being used to provide the application layer function to the interaction layer; The storage layer is used for storing key files and ciphertext files.
[0034] In this technical solution, the interaction layer is the interface for the operator to interact with the system, and provides an intuitive operating environment including multiple interactive buttons. The operator selects the operation to be performed by clicking the button, and the operation is, for example, key generation, encryption, decryption, and calculation. When the operator clicks the button, the interaction layer calls the corresponding function in the application layer through the Wails framework to perform the operation selected by the operator. The application layer includes a CKKS homomorphic encryption module, which is responsible for performing actual encryption operations such as key generation, encryption, decryption, and calculation. It can be considered that the CKKS homomorphic encryption module implements the homomorphic encryption algorithm, allowing calculations to be performed directly on encrypted data without decryption first. In a specific application, the application layer function responds to requests from the interaction layer, performs corresponding encryption operations, and then returns the results to the interaction layer. The storage layer is used for the storage layer to store key files and ciphertext files. Among them, the key file contains keys for encryption and decryption, and the ciphertext file contains encrypted data.
[0035] Therefore, by using homomorphic encryption technology, this system allows calculations to be performed in the encrypted state of data, thereby greatly improving the security of data; the interaction layer provides an operator-friendly interface, so that non-technical operators can also easily perform operations such as key generation, encryption, decryption and calculation, simplifying the operation process. Since calculations can be performed directly on encrypted data, the privacy of the data can be protected and unauthorized access to the data during processing can be prevented. Through the Wails framework, the system can quickly respond to operator operations, improving the response speed and availability of the system. Wails is a modern cross-platform desktop application development framework built on the Go language, allowing developers to use familiar front-end technologies (such as HTML, CSS, JavaScript) to create user interfaces. Combined with the logical processing capabilities of the Go backend, the application of homomorphic encryption technology has become more popular, lowering the threshold for using homomorphic encryption technology, and allowing more non-professional operators to use this technology to protect data security.
[0036] In summary, the homomorphic encryption desktop application system not only improves data security and privacy protection, but also simplifies the operating procedures of operators, lowers the technical threshold, and makes homomorphic encryption technology easier to popularize and apply.
[0037] In one embodiment, the application layer further includes: The file management module is used to import and export key files and ciphertext files between different layers, as well as compress and decompress files; The gob serialization and deserialization module is used to serialize and deserialize the data transmitted between the storage layer and the application layer.
[0038] gob is a data serialization format in the Go language, which is used to convert Go language data structures into byte sequences for storage or transmission over the network. Serialization is the process of converting a data structure or object state into a format that can be stored or transmitted (such as a byte stream). Deserialization is the reverse process of serialization, which is to convert a byte sequence back to the original data structure or object state.
[0039] In specific applications, the configuration parameters and key information of the encryption algorithm can be serialized into base64-encoded strings to facilitate transmission between the user interface (i.e., interactive interface) and the back-end logic. At the same time, the operator's operation instructions (such as encryption, decryption, calculation, etc.) are serialized into byte sequences, and the processing results (such as calculated ciphertext) are deserialized and converted into a format that can be displayed by the user interface.
[0040] In one embodiment, the CKKS homomorphic encryption module is implemented based on the open source library lattigo.
[0041] Using the open source library lattigo can simplify the development process because developers can use existing, tested code instead of implementing complex homomorphic encryption algorithms from scratch. At the same time, the open source library lattigo provides a flexible API that allows developers to easily expand and customize homomorphic encryption functions as needed.
[0042] In one embodiment, the CKKS homomorphic encryption module includes a key generation function, a calculation key generation function, an encryption function, a decryption function, an addition function, a subtraction function, a multiplication function and an algorithm parameter configuration function.
[0043] Among them, the key generation function is used to generate a key pair for encrypting and decrypting data. The key pair includes a public key and a private key. The public key is used to encrypt data, while the private key is used to decrypt data. The key generation process follows the specific rules of the CKKS homomorphic encryption algorithm to ensure that the generated key pair can be safely used for subsequent encryption and decryption operations.
[0044] The Generate Compute Key function is used to generate a computation key based on the private key for performing arithmetic operations in the encryption domain. The computation key allows operations such as addition, subtraction, and multiplication to be performed on encrypted data without decrypting the data.
[0045] The encryption function is used to encrypt the original data using the public key to generate ciphertext. The encryption process follows the rules of the CKKS algorithm to ensure that arithmetic operations can still be performed on the data in an encrypted state.
[0046] The decryption function is used to decrypt the ciphertext using the private key and restore the original data. It can be considered that the decryption process ensures that only operators with the private key can access the original data, thereby protecting the privacy of the data.
[0047] Addition, subtraction, and multiplication functions are used to perform arithmetic operations directly on encrypted data. An operation performed on encrypted data produces the same result as performing the same operation on the original data, except that the result is also encrypted.
[0048] The algorithm parameter configuration function is used to configure the parameters of the CKKS algorithm, such as key size, encryption accuracy, etc. By adjusting the parameters, you can balance security and computing efficiency to adapt to different application scenarios.
[0049] In one embodiment, the interactive interface further includes: A key generation module, wherein the key generation module is used to provide a key generation interface when the target action is key generation; An encryption module, the encryption module is used to provide an encryption interface for encrypting the original text when the target action is encryption; A calculation key generation module, wherein the calculation key generation module is used to provide a calculation key generation interface when the target action is calculation key generation; A calculation module, the calculation module is used to provide a calculation interface for obtaining a ciphertext of a calculation result when the target action is calculation; A decryption module is used to provide a decryption interface when the target action is decryption.
[0050] It can be considered that when the operator selects "Generate Key" as the target operation, the system provides a key generation interface. The operator can click the Generate button on this interface to trigger the key generation function, and the system will generate a pair of keys (public key and private key). The generated key will be saved for subsequent encryption and decryption operations.
[0051] When the operator selects "encryption" as the target operation, the system provides an encryption interface for encrypting the original text. The operator enters or selects the original data to be encrypted (such as text or numbers) on this interface and selects the previously generated public key. The operator clicks the encryption button, and the system calls the encryption function to encrypt the original data into ciphertext and save the ciphertext.
[0052] When the operator selects "Generate calculation key" as the target operation, the system provides a calculation key generation interface. The operator selects the previously generated private key on this interface and clicks the Generate button to generate the calculation key. The calculation key is used to perform arithmetic operations on encrypted data to ensure the security of the calculation process.
[0053] When the operator selects "Calculate" as the target operation, the system provides a calculation interface for the ciphertext of the calculation result. The operator enters or selects the ciphertext to be calculated (such as an encrypted number) and the calculation key on this interface, and selects the calculation operation (such as addition, subtraction, or multiplication). The operator clicks the calculation button, and the system calls the corresponding calculation function, performs the calculation on the ciphertext, and generates a new ciphertext result.
[0054] When the operator selects "decryption" as the target operation, the system provides a decryption interface. The operator enters or selects the ciphertext of the calculation result to be decrypted on this interface, and selects the previously generated private key. The operator clicks the decryption button, and the system calls the decryption function to decrypt the ciphertext into original data for the operator to view.
[0055] In one embodiment, the key generation interface includes a generation button, a private key area, and a public key area; The encryption interface includes an encryption original text selection button, a public key area and a ciphertext area; The key generation interface includes a private key import button, a private key area and a key key area; The calculation key generation interface includes a calculation key area, a result area and a ciphertext area corresponding to each ciphertext; The decryption interface includes a ciphertext area, a private key area and an original text area.
[0056] In one embodiment, the private key area and the public key area of the key generation interface include a display area and a save button respectively; The public key area of the encryption module includes a display area and an encryption button, and the ciphertext area of the encryption module includes a display area and a save button; The private key area of the generated calculation key module includes a display area and a generate button, and the key area of the generated calculation key module includes a save button; Each ciphertext area of the calculation module includes a ciphertext import button and a display area, the calculation key area of the calculation module includes a calculation key import button, a calculation logic selection button and a display area, and the result area of the calculation module includes a save button and a display area; The ciphertext area and the private key area of the decryption module include an import button and a display area respectively, and the original text area includes a decryption button and an original text display area.

Its specific implementation method is consistent with the implementation method and the technical effect achieved recorded in the above-mentioned system embodiment, and some contents will not be repeated here.
[0059] The method comprises: using the interactive layer of the homomorphic encryption desktop application system to receive a key generation selection operation of an operator, calling an application layer function through a key generation module of the interactive interface to generate a private key and a public key and save them; The interactive layer of the homomorphic encryption desktop application system is used to receive the encryption selection operation of the operator, and the encryption module of the interactive interface is used to encrypt and save multiple encrypted original texts according to the saved public key to obtain the ciphertext corresponding to each encrypted original text; The interactive layer of the homomorphic encryption desktop application system is used to receive the key generation selection operation of the operator, and the private key is imported through the calculation key generation module of the interactive interface to generate and save the calculation key; The interactive layer of the homomorphic encryption desktop application system is used to receive the calculation selection operation of the operator, and multiple ciphertexts and calculation keys are imported through the calculation module of the interactive interface to generate and save the calculation result ciphertext; The interactive layer of the homomorphic encryption desktop application system is used to receive the decryption operation of the operator, and the calculation result ciphertext and the private key are imported through the decryption module of the interactive interface to generate and save plaintext, where the plaintext is used to indicate the result of calculating the ciphertext using the calculation module.
