After the application of anti leakage methods, it is easy to re encrypt, resulting in poor anti leakage performance of data flow across domains. Therefore, it is necessary to design a new cross domain cyclic anti leakage method for sensitive network data based on homomorphic encryption. We have constructed a model for cross domain flow and leakage prevention of sensitive data, and designed a cross domain flow and leakage prevention algorithm for sensitive network data using homomorphic encryption, thereby achieving cross domain flow and leakage prevention of data. The experimental results show that the designed anti leakage method for cross domain data flow has high accuracy and detection rate, as well as low false positive rate, false negative rate, memory consumption, and CPU execution time. This proves that the method has good performance, reliability, and certain application value, and has made a certain contribution to reducing the security risk of sensitive data transmission.
