7. A method for secure storage of big data based networks, the method being performed by a transit service station, the method comprising:
acquiring a data transmission request sent by a BIM data sending end, and sending the data transmission request to each BIM data receiving end, so that the BIM data receiving end determines a storage position according to the data transmission request and sends a storage list index; the data transmission request comprises a data storage type and occupied memory; the storage list index comprises a storage position, an allowed data sending time and a BIM data receiving end corresponding ID;
receiving a storage list index sent by each BIM data receiving end, and determining an optimal BIM data receiving end according to the storage list index;
generating the encryption key and the decryption key, and transmitting the encryption key and the allowed data transmission time to the BIM data transmitting end; the BIM data transmitting end encrypts data to be transmitted by using an encryption key to obtain encrypted data, and transmits the encrypted data according to the allowed data transmission time;
the encrypted data and the decryption key are both sent to the optimal BIM data receiving end, so that the optimal BIM data receiving end decrypts the encrypted data by using the decryption key, and the decrypted data is directly stored in a corresponding storage position; the encryption key and the decryption key are matched to each other.
8. The method for securely storing big data in a network according to claim 7, wherein said determining an optimal BIM data receiving end according to the storage list index specifically includes:
determining the distance from the BIM data receiving end corresponding to each ID to the transfer service station;
determining BIM data storage factors according to the corresponding distance of each BIM data receiving end, the speed of receiving data and the allowed data sending time;
and taking the BIM data receiving end corresponding to the minimum BIM data storage factor as an optimal BIM data receiving end.
9. The network security storage method based on big data according to claim 8, wherein the specific calculation formula is as follows:
Q＝(k 1 (t i1 -t 2 ) 2 +k 2 s i +k 3 v i )
wherein t is i1 Allowing data transmission time s for ith BIM data receiving end i V is the distance from the ith BIM data receiving end to the transit service station i For the speed t of receiving data by the ith BIM data receiving end 2 For BIM data transmitting end to transmit data transmission request time k 1 、k 2 、k 3 All are parameter coefficients, and Q is a BIM data storage factor.
10. The method for secure storage of big data based network of claim 7, further comprising:
when the encryption key is invalid, generating the encryption key according to the storage list index corresponding to the optimal BIM data receiving end and the additional parameter factors;
and when the decryption key is invalid, generating the decryption key according to the storage list index corresponding to the optimal BIM data receiving end and the additional parameter factors.
