〇、 explain

Recent work involves technical details , To prevent a very small probability of peer leakage , The summary of work details will not be made public , Only brief work contents are recorded here .

One 、 Job content

1、 According to the idea that popped up last week , Thinking and designing a system , The actual simulation is feasible . But the robustness is not very good for different systems . But for DOLFE The physical system given in this paper can work perfectly .
2、 Then the simulation of this idea , In the same file system , Several other algorithm simulations are written for comparison ：

DFFWM Classic security algorithm
NRD Security algorithms
DOLFE No secure algorithm
DOLFE Security algorithms
DOLFE Improved security algorithm

3、 About the innovation of this idea , There are the following considerations ：

1. Under the new fusion framework, the robustness of attacks is realized ;
2. The system under consideration can be a cloud system , That is, the terminal equipment has no computing capacity , All fusion and security are provided by the fusion center （ Cloud ） To complete ;
3. At the same time, it does not increase the communication pressure at all （ Compared with other fusion and security algorithm systems , Information other than state estimation and covariance needs to be transmitted . This has to be compared with a literature ）.
4. MSE Better than the comparison algorithm , A more stable
5. Add a new attack model , Can consider both offset attack and zero mean Gaussian attack .

4、 Inferiority

1. It is not effective against extremely concealed attacks （ Equivalent to a state without a secure algorithm , No attack detected ）
2. You need to set a threshold , But compared to the NRD for , There are fewer thresholds to set .

Two 、 Experience

Thick and thin hair .

3、 ... and 、 What to do next

1、 Further refine the idea , Make a framework .
2、 Get ready for the opening .
