DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] At present, although traditional data security methods, such as data encryption and access control, can protect data security to a certain extent, there is still a risk of data leakage in a collaborative environment and may affect design efficiency.

[0021] Based on this, an EDA design collaboration data security protection system, method and electronic device provided by an embodiment of the present invention can ensure the security of design data while improving design efficiency.

[0022] To facilitate understanding of this embodiment, firstly, a EDA design collaboration data security protection system disclosed in an embodiment of the present invention is described in detail. Figure 1 The architecture diagram of an EDA design collaborative data security protection system shown illustrates that the system mainly includes: user layer, application layer and cloud platform layer.

[0023] The user layer sets data access policies and access rights for participants (design teams or designers) through the user interface (UI).

[0024] The application layer includes: EDA tools and data processing modules. EDA tools are used to perform EDA design tasks and send the design data of EDA design tasks to the data processing module. In specific implementation, EDA tools perform specific electronic design tasks, such as schematic drawing, PCB layout, and circuit simulation. In the process of performing these tasks, EDA tools need to interact with the data processing module for data. EDA tools send design data to the data processing module for processing, and receive the processed design data to continue the design task.

[0025] The data processing module is used to segment, preprocess, encrypt, decrypt and reconstruct the design data, and return the processed design data to the EDA tool. In specific implementation, the data processing module is responsible for the segmentation, preprocessing, encryption, decryption and reconstruction of the design data to ensure the security and integrity of the data.

[0026] The cloud platform layer is used to perform the computing tasks of the EDA design tasks based on the secure multi-party computing protocol, and send the encrypted computing results to the data processing module. In the specific implementation, the data processing module sends the encrypted data to the cloud platform layer for computing and storage, and receives the encrypted computing results and other necessary data from the cloud platform layer.

[0027] The above-mentioned EDA design collaboration data security protection system provided by the present invention divides the EDA design data into multiple parts and adopts a secure multi-party computing protocol to enable each participant (design team or designer) to perform joint computing without disclosing their respective data. This not only protects the security of the design data, but also improves the design efficiency.

[0028] In one embodiment, the data processing module includes: a data segmentation component, a data preprocessing component, a data encryption component, a data decryption component and a data reconstruction component.

[0029] The data segmentation component is used to obtain the design data of the EDA design task, and then segment the design data and distribute it to the corresponding participants.

[0030] In the specific implementation, the design data is finely segmented according to functional modules (such as power modules, signal processing modules, control modules, etc.) and levels (such as behavioral level, logical level, circuit level and physical level), and the segmented design data is allocated to the corresponding participants, that is, each participant only receives and processes the data that it is responsible for. At the same time, the data of each module and level is marked and stored in different encrypted containers through the collaborative platform management UI.

[0031] The data preprocessing component is used to preprocess the segmented design data. In the specific implementation, each participant can preprocess the design data locally, such as encoding and encryption, to ensure the security of the original data.

[0032] The data encryption component is used to encrypt the pre-processed design data to obtain the encrypted data of each participant, and transmit the encrypted data to the cloud platform that performs the computing task based on the communication SSL protocol, and receive the encrypted computing results of each participant transmitted by the cloud platform through the communication SSL protocol.

[0033] In one embodiment, the data encryption component is specifically used to: generate a public key and a private key pair based on a preset key generation algorithm; encrypt the preprocessed design data based on the public key to obtain the encrypted data of each participant, and distribute the share of the private key to the corresponding participant.

[0034] In specific implementation, an intelligent key management system is used to generate a public key and a private key pair through a secure key generation algorithm (such as AES-GCM). The public key is used to encrypt data, and the share of the private key will be distributed to each participant. Specifically, the private key can be distributed to the corresponding participants through a secure communication protocol (such as TLS / SSL) to ensure the security of the key during transmission. In the embodiment of the present invention, each participant can only receive his own share of the private key and cannot restore the original data.

[0035] Furthermore, after the data is encrypted, the communication SSL protocol can be used to transmit the encrypted data to the cloud platform that performs the computing task, and receive the encrypted computing results of each participant transmitted by the cloud platform through the communication SSL protocol.

[0036] The data decryption component is used to decrypt the encrypted calculation results of each participant to obtain the calculation results of each participant.

[0037] In one embodiment, when decrypting data, the private key shares of each participant are first obtained and then combined; then the encrypted calculation results are decrypted based on the combined private key shares to obtain the calculation results of each participant.

[0038] In the specific implementation, the participants prepare for the decryption operation and ensure that all necessary private key shares are available for the decryption process. The interactive decryption method is adopted in the embodiment of the present invention. Through an interactive process, the participants cooperate to decrypt the encrypted calculation results. During the decryption process, all participants need to provide private key shares to ensure that only when all participants cooperate can the correct result be decrypted. Specifically include: (1) Private key share collection: When the encrypted calculation results need to be decrypted, each participant needs to provide his or her own private key share to ensure the cooperation of all participants.

[0039] (2) Private key share combination: The private key shares of each participant are combined through a secure interactive process. The combination process needs to ensure that there are enough private key shares to successfully decrypt.

[0040] (3) Data decryption: After the private key shares are successfully combined, the complete private key can be used to decrypt the encrypted data to obtain the original data, that is, the original calculation result.

[0041] The data reconstruction component is used to verify the calculation results of each participant, and after the verification, integrate the design data of each participant to obtain the design database.

[0042] In one embodiment, when reconstructing data, the calculation results of each participant are first verified based on a digital signature verification algorithm; if the calculation results of each participant meet the design requirements, the design data of each participant are uniformly formatted and integrated to obtain a design database.

[0043] In specific implementation, after obtaining the calculation results of each participant, it is necessary to verify the results and reconstruct the data to ensure the correctness of the results and the integrity of the data. Specifically, the calculation results are verified by a digital signature verification algorithm to ensure that all calculation results meet the design requirements and expected results. When the calculation results of all participants are verified, the design data of each participant is integrated together, including the circuit elements, layout information, simulation data, etc. provided by different participants. The unified formatting and organization forms a complete and consistent EDA design database or file set. These data will be used for subsequent circuit manufacturing, testing or further simulation analysis.

[0044] In one embodiment, the cloud platform layer includes: cloud computing resources and a security management module.

[0045] Cloud computing resources are used to receive and store encrypted data transmitted by the data processing module, and to jointly calculate the encrypted data of each participant based on the secure multi-party computing protocol to obtain the encrypted calculation results of each participant, and transmit the encrypted calculation results to the corresponding participants through the communication SSL protocol.

[0046] In specific implementation, cloud computing resources perform EDA computing tasks and work with the security management module to ensure data security. The interaction between cloud computing resources and the security management module ensures the safe execution of computing tasks and the protection of data.

[0047] Specifically, in EDA design collaboration, fast calculation results are a key requirement. Therefore, it is particularly important to select a secure multi-party computing (SMPC) protocol with high computational efficiency. In an embodiment of the present invention, a threshold fully homomorphic encryption (FHE) protocol can be used, which allows calculations to be performed directly on encrypted data without decryption, thereby improving computational efficiency.

[0048] Specifically, when the threshold fully homomorphic encryption protocol is used in the embodiment of the present invention to perform EDA computing tasks, a lightweight encryption algorithm (such as AES-GCM) is used to encrypt and protect the data during data transmission and computing, ensuring that the data remains encrypted even during transmission. The encrypted data will be transmitted to the server or platform (i.e., cloud computing resources) that performs the computing via a secure communication SSL protocol.

[0049] The participants send the encrypted data to the cloud server or other entity that performs the calculation. The cloud server or other entity that performs the calculation receives the encrypted data and starts to perform the necessary EDA calculation tasks. Due to the use of threshold fully homomorphic encryption technology, the cloud server or other entity that performs the calculation can directly perform calculations on the encrypted data without decrypting the original data. After the calculation is completed, the cloud server or other entity that performs the calculation generates the calculation results and stores these results in encrypted form. The encrypted calculation results will be sent back to the participants through the secure communication SSL protocol.

[0050] The security management module is used for key management, access control of various participants and security auditing.

[0051] In specific implementation, the security management module is responsible for functions such as key management, access control and security audit to ensure the security of data on the cloud platform.

[0052] In the embodiment of the present invention, through the communication interaction between the above modules, the system can efficiently perform electronic design tasks while ensuring the security and integrity of data. Each module has a specific function and works in conjunction with other modules to achieve the functions of the overall system. This modular design makes the system easier to maintain, expand and upgrade.

[0053] For ease of understanding, the present invention also provides an EDA design collaboration method, see Figure 2 As shown, it mainly includes the following steps 1 to 5: Step 1: Data segmentation.

[0054] In the specific implementation, the EDA design data is finely divided according to functional modules (such as power module, signal processing module, control module, etc.) and levels (such as behavioral level, logical level, circuit level and physical level).

[0055] Step 2: Data allocation and preprocessing.

[0056] In the specific implementation, each team or designer only receives and processes the data they are responsible for after data segmentation. Each team pre-processes the data locally, such as encoding and encryption, to ensure the security of the original data.

[0057] Step 3: Key generation and distribution.

[0058] In the specific implementation, the intelligent key management system is used to generate public and private key pairs through a secure key generation algorithm. The public key is used to encrypt data, and the share of the private key will be distributed to each participant. The secure communication protocol SSL and encryption technology are used to ensure the security of the key during transmission.

[0059] Step 4: Joint calculation.

[0060] In the specific implementation, the threshold fully homomorphic encryption protocol is used to perform EDA computing tasks. The specific process can be found in the above embodiment and will not be repeated here.

[0061] Step 5: Result verification and data reconstruction.

[0062] In the specific implementation, after obtaining the calculation results of each team, the calculation results are verified through the digital signature verification algorithm to ensure that all results meet the design requirements and expected results. After the calculation results of all teams are verified, these data are integrated together to form a complete and consistent EDA design database or file set.

[0063] The above-mentioned system provided by the embodiment of the present invention divides the EDA design data into multiple parts and adopts SMPC technology to enable each design team or designer to perform joint calculations without disclosing their respective data, which not only protects the security of the design data but also improves the design efficiency. In addition, the calculation results are verified by a specific verification algorithm to ensure the correctness and reliability of the results. Finally, when all design teams or designers have completed their respective tasks, the system will reconstruct the complete EDA design data based on the calculation results of all parties, and further optimize to ensure the quality and performance of the design.

[0064] The embodiment of the present invention also provides an EDA design collaboration data security protection method, which is applied to the EDA design collaboration data security protection system provided in the above embodiment, see Figure 3 The flowchart of a method for protecting EDA design collaboration data security is shown, indicating that the method mainly includes the following steps S301 to S305: Step S301: Acquire design data of an EDA design task, and divide the design data and distribute it to corresponding participants.

[0065] Step S302: pre-processing the segmented design data, and encrypting the pre-processed design data to obtain encrypted data of each participant.

[0066] Step S303: Based on the secure multi-party computing protocol, the encrypted data of each participant is jointly calculated to obtain the encrypted calculation results of each participant.

[0067] Step S304: decrypt the encrypted calculation results of each participant to obtain the calculation results of each participant.

[0068] Step S305: verify the calculation results of each participant, and after the verification, integrate the design data of each participant to obtain a design database.

[0069] The above-mentioned EDA design collaboration data security protection method provided by the present invention divides the EDA design data into multiple parts and adopts a secure multi-party computing protocol to enable each participant (design team or designer) to perform joint computing without disclosing their respective data. This not only protects the security of the design data, but also improves the design efficiency.
