Electronic payment protocols play a vital role in electronic commerce to ensure the security of transaction process. Current electronic payment protocols based on complex mathematical problems will be vulnerable facing a quantum computer. In order to enhance the security against quantum computers, quantum cryptography is introduced into electronic payment protocols. Although the quantum cryptography...
Robot-assisted needle insertion technology is now widely used in minimally invasive surgeries. The success of these surgeries highly depends on the accuracy of the position and orientation estimation of the needle tip. In this paper, we proposed an optical tracker based registration method for the marker-robot-needle tip registration in a robot-assisted needle insertion surgery. The method consists...
While some logic analysis method has been used in the analysis of electronic commerce protocols for its simplicity, their lack of the ability in time description makes it helpless in the analysis of timeliness, which is one of the most important properties of electronic protocols. a novel logic is proposed by adding a simple time expression and analysis method to remedy the defect. Then a widely discussed...
