7. the data security authentication method according to claim 4 based on BIM, which is characterized in that step S23 are as follows: will walk
BIM drawing to be uploaded is encrypted in the Crypted password obtained in rapid S21, obtains BIM drawing third time to be uploaded and adds
Ciphertext data.
8. the data security authentication method according to claim 3 based on BIM, which is characterized in that step S32 are as follows: utilize
Crypted password decryption is uploaded to the encryption BIM drawing data of server, obtains BIM drawing third time ciphertext data.
9. the Verification System of the data security authentication method described according to claim 1~one of 8 based on BIM, feature exist
In, including receive judgment module, upload encrypting module and download decryption module；
The judgment module that receives judges whether to receive the password to be encrypted sent to login user for BIM system；If BIM
System receives the password to be encrypted sent to login user, and the password to be encrypted includes number, Chinese character, capitalization, small
It writes one of female, spcial character or any combination, then password to be encrypted is transferred to upload encrypting module；
If BIM system does not receive the password to be encrypted sent to login user, BIM system sends upper one to login user
The secondary password to be encrypted that BIM system is sent to login user；Password to be encrypted is then transferred to upload encrypting module；
It uploads after encrypting module encrypts BIM drawing for BIM system and is uploaded to server；
Download decryption module be used for login user the BIM drawing encrypted on server is locally downloading, BIM is checked after decryption
Drawing.
10. the Verification System of the data security authentication method according to claim 9 based on BIM, which is characterized in that upper
Pass encrypting module in the following steps are included:
S21, BIM system utilize the public spoon to login user to treat Crypted password and are encrypted, and obtain Crypted password,
The Crypted password of acquisition is sent to login user by BIM system；
BIM drawing to be uploaded by hash algorithm, is obtained first yard of Hash, utilizes the private spoon of BIM system by S22, BIM system
To first yard of progress computations of Hash, first yard of Hash of encryption is obtained；
The Crypted password obtained in step S21 is encrypted BIM drawing to be uploaded, obtains BIM to be uploaded by S23
Drawing first time encryption data recycles the private spoon of BIM system to carry out at encryption BIM drawing first time encryption data to be uploaded
Reason, obtains second of encryption data of BIM drawing to be uploaded, then recycles the public spoon to login user to BIM drawing to be uploaded
Second of encryption data is encrypted, and obtains BIM drawing third time encryption data to be uploaded；
S24 adds the BIM drawing to be uploaded third time obtained in first yard of the encryption Hash and step S23 that obtain in step S22
Ciphertext data packing is uploaded to server；
In download decryption module the following steps are included:
S31, it is to login user that the encryption BIM drawing data uploaded onto the server is locally downloading；
S32 is uploaded to the encryption BIM drawing data of server using the private spoon decryption to login user, obtains BIM drawing first
Secondary ciphertext data；It recycles the public spoon of BIM system to decrypt BIM drawing first time ciphertext data, obtains second of BIM drawing and decrypt
Then data decrypt second of ciphertext data of BIM drawing using Crypted password, obtain BIM drawing third time ciphertext data；
The BIM drawing third time ciphertext data obtained in step S32 is carried out hash algorithm by S33, obtains decryption Hash code, then
Computations are carried out to decryption Hash code using the public spoon of BIM system, obtain first yard of Hash of decryption；
S34 judges whether first yard of decryption Hash is identical as first yard of Hash of encryption:
If first yard of decryption Hash is not identical as first yard of Hash of encryption, pass through the public spoon or BIM system to login user
Public spoon find the encryption BIM drawing of upload as index；
Decrypt first yard of Hash, the then BIM drawing third time ciphertext data that in step S32 obtains identical as first yard of Hash of encryption
For BIM system BIM drawing to be uploaded.
