Multi-domain flow discovery technique based on dual certificate storage across domains

Abstract

A cross-domain multi-copy of flow discovery mechanism based on dual certificate storage was proposed to address the issues of privacy information leakage caused by the intentional or inadvertent retention of information when information was frequently exchanged across nodes and systems in a ubiquitous sharing environment. This mechanism could track the propagation path and channel and create a multi-copy propagation graph of the information.The dual certification included certification for both passive operation and active circulation, depending on when and how it was granted.
