With the rapid development of network technology and the increasingly complexity of system function, the embedded system is facing more and more serious threats. Previous researches on kernel monitoring and protection widely relies on higher privileged system components, such as hardware virtualization extensions, to isolate security tools from potential kernel attacks. These approaches increase both...
Recent technological advances have accelerated the design and worldwide deployment of mobile payment systems (m-payment). However, m-payment over open devices and networks poses security challenges of a new dimension that users disclose lots of sensitive information and privacy can't be protected properly in open environment. In this paper, we propose a mobile payment architecture employing with trusted...
Recent technological advances have accelerated the design and deployment of kinds of secure applications on smartphones. Although users can access and handle their data flexibly and stably with mobile devices, not only computing devices, it poses security challenges of a new dimension that users disclose lots of sensitive data and privacy information over open devices and networks as well. Thus, more...
Linear and nonlinear optical absorption coefficients of spherical dome shells are theoretically investigated within analytical wave functions and numerical quantized energy levels. Our results show that the inner radius, the outer radius and the cut-off angle of spherical dome shells have great influences on linear and nonlinear optical absorption coefficients as well as the total optical absorption...
