This paper presents Flow Walker, a new dynamic taint analysis framework which focuses on eliminating the bottlenecks of the existing tools. The framework proposes a multi-taint-tag assemble level taint propagation strategy. Flow Walker separates taint tracking operations from execution with an off-line structure, uses memory-mapped file to enhance IO efficiency and processes taint paths during execution...
Software vulnerabilities become methods by which an attacker can take control of the victim's system, and those critical bugs cluster in dangerous spot codes. However, fuzz testing provides low code coverage and serious security bugs may be missed potentially, while symbolic execution based testing encounters path explosion and bug trigger problem. To deal with the security issue above, we highlight...
Web applications are vulnerable targets of security attacks. Among the well known attack type - XSS(Cross-Site Scripting), the most threatening is Stored XSS. Since most static analysis methods refer to Reflected XSS but few concentrate on Stored XSS which is more devastating, plus the fact that pure static analysis offers high false positive rate, we present a static Stored XSS detection algorithm...
An real-time temperature and humidity measurement system is designed with SHT21 temperature and humidity sensors. Communication is controlled by XC2S50-5TQ144 Field programmable gate array and measurement data can be shown in real time by the PC software. The results show that the system can not only accurately measure the real-time temperature and humidity, but also rapidly respond to the mutations...
