The number of malware is increasing rapidly and a lot of malware use stealth techniques such as encryption to evade pattern matching detection by anti-virus software. To resolve the problem, behavior based detection method which focuses on malicious behaviors of malware have been researched. Although they can detect unknown and encrypted malware, they suffer a serious problem of false positives against...
We address secure secret key distribution in wireless communication systems. There is the secrecy capacity concept that it can distribute information which the third parties can not eavesdrop because of the noise over the distribution channel. Then, we address secure secret key distribution in wireless communication systems using secrecy capacity concept. Wireless channel is noisier compared with...
In this paper, we expand the human-friendly control concept which has been restricted only to the robot controls into general assistive controls. For a demonstration of this generalized human-friendly control, we adopt a power-assisted wheelchair and apply a novel control to it. We investigate some requirements for this generalized human-friendly control and suggest solutions to it. Our solution approach...
In this paper, novel multirate two-degree-of-freedom controllers are proposed for digital control systems, where it is restricted that the speed of the A/D converters are slower than that of the D/A converters. The proposed feedforward controller assures the perfect tracking at M inter-sampling points. Moreover, it is shown that the structure of the proposed perfect tracking controller is very simple...
