Detailed Description
In order to more clearly illustrate the invention, the invention is further described below with reference to preferred embodiments and the accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.
In order to improve the security of the cloud simulation platform, as shown in fig. 1, the embodiment discloses a security guarantee system for the cloud simulation platform. In this embodiment, the system includes a data encryption module, an access control module, and a virtual simulation module.
As shown in fig. 2, the data encryption module is configured to encapsulate and compile a simulation model of a user to obtain an encrypted simulation model, and upload the encrypted simulation model to the cloud simulation platform under the control of the user. In a preferred embodiment, the data encryption module may be disposed in a terminal facing a user, the data encryption module may encapsulate the simulation module, encapsulate the entire simulation model into one module, and provide, for the model, only the interfaces necessary for the use/operation of the module, such as input/output, parameter configuration (e.g., external parameters required in the model, initialization of parameters in the model), and the like, for the user. For the packaged model, in order to prevent a thief from unsealing the model and stealing the model, the packaged model is compiled by adopting encryption and compilation (anti-reverse compilation technology) to obtain a compiled model which can be uploaded to a cloud simulation platform. For the encryption and compilation technology, there are mature technologies, for example, MAXTOCODE adopts a mode of completely surpassing the traditional obfuscation means to protect the source code, and completely encrypts the code, so that the code has no way of decompilation. The application of the module is mainly performed at a platform simulation model provider (designer), and the type of an uploading file is limited at a model uploading port, so that the designer is required to upload the model after packaging, encrypting and compiling the designed model. When the virtual environment uses the model for simulation, a method of decrypting and then using is adopted for simulation. Because the model is still packaged after decryption, the internal details of the model are still invisible to a user during simulation, and therefore the model is protected.
In the data encryption module, software used by a user for establishing a simulation model has certain diversity, and the software used by designers in different fields is different. For example, for designers in the control and communication fields, Matlab/Simulink is generally an indispensable simulation modeling tool, while for designers in the structural field, ANSYS software and the like. For the encryption and the compilation of the model obtained by a plurality of simulation model establishing software, two alternative implementation modes exist: one way is to encapsulate the model as in this embodiment, only expose the required interface, and then encrypt it in a uniform encryption manner. In other embodiments, the Net source code may be encrypted by referring to MAXTOCODE, and a universal encryption compiling software may be developed for models built by a set of model building software in different fields by analyzing the characteristics of the common model building software.
The access control module is used for providing two working environments of a collaborative simulation mode and a file processing mode for a user, and in the file processing mode, the user operates an encryption simulation model of the cloud simulation platform. For example, in a file processing mode, the system can process the model and the data file differently through file type identification, and the access control module can provide two ways of model file processing and data file processing for a user to process the simulation model and data of the cloud simulation platform. For model file processing, a user can only upload a simulation model designed by the user to a cloud simulation platform through an access control module or delete an encrypted simulation model uploaded by the cloud simulation platform user before, but any simulation model of other users cannot be downloaded. The simulation data file (including external parameters, initialization parameters and the like) can be uploaded, downloaded and deleted. As shown in fig. 3, in practical applications, the access control module may include an interaction module, which displays a login interface to a user, and provides an intermediate connection sub-module for the user who passes login verification, where the sub-module is selected by the user in an access mode, if the sub-module is selected as collaborative simulation, the virtual simulation environment of the cloud simulation platform is entered, and if the model and the file processing mode are selected, the virtual simulation environment is entered into the cloud simulation platform by processing a model file. In the latter case, the user may perform the processing of the data file, and the uploading/deletion of the model, in an operation manner similar to a remote desktop.
The virtual simulation module is used for providing a virtual cloud simulation environment for the user in the collaborative simulation mode, and forbidding all operations of the user outside the simulation experiment until the user exits the cloud simulation environment.
In the collaborative simulation mode, the user can combine or connect the uploaded encryption simulation model with the required simulation models of other users, so that the collaborative simulation at the cloud simulation platform end is completed. In the mode, a user needs to enter a virtual simulation environment for simulation experiments through a collaborative simulation mode of the access control module, when the user enters the virtual simulation environment, the operation and control of the local computer provided with the access control module are temporarily prohibited/cut off, other processes except a system process of the local computer are ended, prohibited to run or hung, and all the operations of the user are performed in the virtual simulation environment provided by the cloud simulation platform. In the virtual simulation environment, a user can perform joint simulation with other simulation models, import model configuration data, export simulation data and modify the simulation models designed by the user, and the other simulation models in the platform have no modification right.
The system of the invention constructs an isolated environment, thereby avoiding the flow of models of other users to a local system through means of exporting, copying, pasting and the like in the simulation process, and forming embezzlement to the models. The method comprises the steps that other users in the platform cannot obtain complete details about a model except for the use of the model from the platform, so that the model cannot be downloaded directly, or the model cannot be obtained to the local from the cloud simulation platform by means of copying and pasting, mobile phone shooting, screen capturing, screen recording and other operations, so that the model is stolen, other users in the platform cannot directly modify an access model of the cloud simulation platform, the simulation model uploaded by the users is prevented from being damaged, and further the problem or hidden danger of multidisciplinary collaborative simulation is prevented.

The access control module is used for providing two working environments of a collaborative simulation mode and a file processing mode for a user, in the file processing mode, the user operates an encryption simulation model of the cloud simulation platform, wherein the encryption simulation model is obtained by packaging and compiling the simulation model of the user by the data encryption module and is uploaded to the cloud simulation platform under the control of the user; the virtual simulation module is used for providing a virtual cloud simulation environment for the user in the collaborative simulation mode, and forbidding all operations of the user outside the simulation experiment until the user exits the cloud simulation environment. The simulation experiment comprises modification of a simulation model uploaded by a user, joint simulation with other simulation models, model configuration data import and simulation data export.

The data encryption module is used for packaging and compiling a simulation model of a user to obtain an encrypted simulation model, and uploading the encrypted simulation model to the cloud simulation platform under the control of the user, so that the access control module provides two working environments of a collaborative simulation mode and a file processing mode for the user, and in the file processing mode, the user operates the encrypted simulation model of the cloud simulation platform; and the virtual simulation module provides a virtual cloud simulation environment for the user in the collaborative simulation mode, and prohibits all operations of the user outside the simulation experiment until the user exits the cloud simulation environment.
