Research on Cross-host Dynamic Taint Tracking Technology

In order to solve the problem that taint tracking system can not realize cross-host dynamic taint tracking,based on Temu system,a taint tracking method based on Application Programming Interface(API) Hook is presented.It fulfills the interception of network I/O related system calls by Hook plug-ins,which embeds Hook services into API function calls to accomplish cross-host taint propagation.Taint data and information are encapsulated by Hook plug-in at sender.Hook plug-in analyzes data packets and marks taint data tainted according to taint information at receiver,so that cross-host dynamic taint tracking is realized.Experimental result indicates that the prototype system can implement cross-host taint propagation,which is helpful to application with dynamic taint tracking in distributed environment.
