Abstract
An encryption method for a BIM family library platform comprises the following steps that firstly, original rfa family files of a user are uploaded to a file server through a client, and the rfa family files are encrypted and stored on a file layer through an encryption algorithm; when a user selects to load a family into Revit from a family library, downloading an rfa family file from a file server for decryption; before a user loads a family into a project, encrypting each component and parameter of the family, and then loading the encrypted family into the project for use; and finally, the rfa family file local to the user is subjected to file encryption again. The invention ensures the safety of the rfa family files uploaded by the user at each stage through a scientific method, is not stolen by others, and ensures the safety of originators of the rfa family files.
Description
Technical Field
The invention relates to the technical field of encryption, in particular to an encryption method for a BIM family library platform, and specifically relates to an encryption method for a Revitrfa family file based on a BIM technology.
Background
The current BIM technology is rapidly developed, BIM software mainly based on Revit is widely applied, wherein rfa family files play a very important role in a BIM model, and the BIM model can be more accurate and detailed only by possessing a perfect family library platform, so that how to protect the security of the rfa family files is very important.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide an encryption method based on the Revitrfa family files of the BIM technology, which ensures the security of the rfa family files uploaded by a user at each stage through the application of the BIM technology, is not embezzled by others, and ensures the intellectual property of originators of the rfa family files.
In order to achieve the purpose, the invention adopts the technical scheme that:
an encryption method for a BIM family library platform, comprising the steps of:
the method comprises the following steps: uploading the manufactured rfa family file to a cloud server from the local through a client, and encrypting the file;
step two: when the rfa family file is selected from the family library and loaded, the rfa family file in the server is downloaded and cached to the local and decrypted;
step three: before loading the rfa family file into the item, opening the rfa family file for view level encryption;
step four: parameter encryption is carried out on the rfa family file encrypted in the third step;
step five: loading the encrypted rfa family file into an item used by a user;
step six: and fifthly, the rfa family file is loaded into the item, and the rfa family file cached to the local user is encrypted in the first step again to ensure the security of the cached file.
Further, in the first step, the rfa family file is encrypted by using a DES encryption algorithm, DES is a symmetric encryption algorithm, the encrypted file can be decrypted by using a correct key and uploaded to an ari cloud OSS object storage server through a client, and OSS is a massive, safe, low-cost, high-durability cloud storage service.
Further, in the second step, the user downloads the rfa family file from the OSS object storage server through the client and caches the rfa family file locally, and decrypts the file through the DES algorithm and the key.
Further, the encryption of the views in step three includes the steps of setting the visibility of each member, label and other visible instances of the family in each view to be hidden, and ensuring that the content in each view is empty when the family is opened by editing the family in the model.
Further, encrypting the rfa family file parameters in the fourth step means that parameters related to geometric characteristics or visibility in the family parameters are replaced by adding new shared parameters, the new parameters are encrypted by using an old parameter name through a base64 algorithm, a prefix and a suffix are added for naming, and the parameters are hidden, so that the association between the family parameters and the family is cut off, and the original family loses the parametric characteristics.
Further, in the fifth step, the family completed by the fourth step and the fifth step is loaded into the item, the additional parameter of the family is added with mark information to identify the encrypted family loaded by the family library when the family is loaded, and the condition that the same name family exists in the item is processed according to the selection of the user.
The invention has the beneficial effects that:
the Revit software does not provide encryption protection for the rfa family files, which means that the rfa family files created by technicians are easily stolen by others in the circulation process of the BIM model.
In conclusion, by adopting the technical scheme of the invention, full-life-cycle encryption protection can be performed on the rfa family files uploaded to the cloud, downloaded to the local and loaded into the project by the user, so that the labor results of technical personnel are prevented from being stolen in the circulation process, and the intellectual property of the technical personnel is protected.

FIG. 1 is a flow chart of the present invention.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, an encryption method for a BIM family library platform includes the following steps:
the method comprises the following steps: uploading the manufactured rfa family file to a cloud server from the local through a client, and encrypting the file;
step two: when the rfa family file is selected from the family library and loaded, the rfa family file in the server is downloaded and cached to the local and decrypted;
step three: before loading the rfa family file into the item, opening the rfa family file for view level encryption;
step four: parameter encryption is carried out on the rfa family file encrypted in the third step;
step five: loading the encrypted rfa family file into an item used by a user;
step six: and fifthly, the rfa family file is loaded into the item, and the rfa family file cached to the local user is encrypted in the first step again to ensure the security of the cached file.
Further, in the first step, the rfa family file is encrypted by using a DES encryption algorithm, DES is a symmetric encryption algorithm, the encrypted file can be decrypted by using a correct key and uploaded to an ari cloud OSS object storage server through a client, and OSS is a massive, safe, low-cost, high-durability cloud storage service.
Further, in the second step, the user downloads the rfa family file from the OSS object storage server through the client and caches the rfa family file locally, and decrypts the file through the DES algorithm and the key.
Further, the encryption of the views in step three includes the steps of setting the visibility of each member, label and other visible instances of the family in each view to be hidden, and ensuring that the content in each view is empty when the family is opened by editing the family in the model.
