In this paper, a novel LVTSCR-based device for electrostatic discharge (ESD) protection of integrated circuits (ICs) is designed, fabricated and characterized. The proposed device is similar to the conventional LVTSCR but it has an embedded PMOSFET in the anode n-well to enhance the turn on speed, the clamping capability and the robustness. This is possible because the embedded PMOSFET provides...
In the past researches, most of the authentication protocols were designed in an effort to solve the RFID security and privacy problem regarding the encrypted communication between the database and readers, and readers and tags. Based on the proposal of mobile agent device for RFID privacy protection (MARP), some security problems have been exposed. Later on, protecting the privacy with a mobil...

High power LED converter combined with switching power supply and current adjustment device for is presented. The switching power supply provides one stabilized voltage source, and the current adjustment device controls the output currents with a desired constant current and the over-load protection. The experiment results shows the circuit can work well and pass the load test and the electroma...
The current device-centric protection model against security threats has serious limitations from the final user perspective, among the other the necessity to keep each device updated with the latest security updates and the necessity to replicate all the security polices across all devices. In our model, the protection is decoupled from the users terminals and it is provided through a Trusted ...
One of the driving forces behind the development of 3G systems is the potential to deliver complex content to consumers. This is evident from the growing collaboration between broadcast and mobile network operators, and the expectation that future broadcast receivers will be able to forward content to mobile devices. One challenge in providing such a service is the requirement for content prote...
