constructing a downloading request according to the data downloading address in the metadata information, and sending the downloading request to the alliance member equipment for storing the data set corresponding to the metadata information; wherein, the download request carries the data set number of the requested data set, the download request time and the signature of the request information;

and when the data ciphertext corresponding to the metadata information is downloaded, decrypting the data ciphertext by using the decrypted key to obtain a data set corresponding to the metadata information.

4. The method of claim 3, wherein the metadata information further comprises: a hash value; wherein the hash value is generated from data in the dataset;

after the data ciphertext is decrypted by using the decrypted key to obtain the data set corresponding to the metadata information, the method further includes:

and verifying whether the data in the data set is tampered or not by using the hash value in the metadata information.

5. The method of claim 2, further comprising:

when receiving a downloading request sent by other alliance member equipment, checking whether the time for requesting downloading carried in the downloading request is within the set effective sharing time;

if the verification is successful, acquiring a public key of the alliance member device which sends the downloading request to verify the digital signature in the downloading request;

if the verification is passed, responding a data cipher text corresponding to the data set number carried in the downloading request to the alliance member equipment sending the downloading request; otherwise, the download request is rejected.

6. The network measurement data storage device is applied to the coalition member equipment in a storage system comprising the coalition member equipment and coalition member management equipment; the device comprises: a receiving unit, an aggregation unit, a generation unit and a sending unit;

the receiving unit is used for receiving network measurement data uploaded by a terminal in the area;

the aggregation unit is used for aggregating the network measurement data received by the receiving unit into a data set with a preset value size according to the receiving time; allocating data set serial numbers to the data sets according to the receiving time sequence;

the generating unit is configured to generate metadata information of the data sets aggregated by the aggregating unit, and a block payload corresponding to the metadata information; wherein the metadata information includes: federation member ID and data set number; the alliance member ID is distributed to the alliance member device by the alliance member management device; the data set number consists of the ID of the coalition members and the data set serial number;

the sending unit is configured to send the block load generated by the generating unit to the coalition member management device, so that when the coalition member management device passes the block load verification, the block load is updated and uplinked according to the time for receiving the block load.

7. The apparatus of claim 6,

the generating unit is further configured to encrypt the data set using a randomly generated symmetric encryption key to generate a data ciphertext of the data set; when the data ciphertext is stored, a data download address of the data ciphertext is generated; the generated metadata information further includes: when sharing the member list and the data download address, wherein the sharing member list comprises: a federation member ID and an encryption key for a federation member sharing data in the dataset; the encryption key is generated by encrypting a randomly generated symmetric encryption key by using a public key distributed by the coalition member management device for coalition members sharing data in the data set.

8. A network measurement data storage system, the storage system comprising: alliance member device and alliance member management device;

the alliance member equipment receives network measurement data uploaded by a terminal in the area; aggregating the received network measurement data into a data set with a preset value size according to the receiving time; allocating data set serial numbers to the data sets according to the receiving time sequence; generating metadata information of the data set and a block load corresponding to the metadata information; wherein the metadata information includes: federation member ID and data set number; the alliance member ID is distributed to the alliance member device by the alliance member management device; the data set number consists of the ID of the coalition members and the data set serial number; sending the block payload to the federation member management device;

when the block load sent by the coalition members is received and verified by the block load verification code, the coalition member management equipment updates the uplink of the block load according to the time for receiving the block load.

9. An electronic device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, characterized in that the processor implements the method according to any of claims 1-5 when executing the program.

10. A computer-readable storage medium, on which a computer program is stored, which program, when being executed by a processor, is adapted to carry out the method of any one of claims 1 to 5.
