This paper addresses a pursuer tracking problem where the pursuer's acceleration is given by a proportional navigation (PN) guidance law with a time-varying navigation ratio which varies with the relative range between the pursuer and its target. Based on a motion model that exactly describes the relative motion and the PN guidance law, a novel fil...

An active defense scheme in which a ballistic missile launches a defending missile to intercept the incoming intercepting missile is considered. Compared with traditional passive evasion strategies, the active defense scheme can greatly increase the ballistic missile’s survival rate. Different from many terminal guidance laws using the line-of-sigh...

The anonymity is the most important property of group signature schemes. Traditional schemes suppose that a signer is reluctant to leak his identity to a verifier. In some real scenarios, this supposition does not hold. A signer may want to cooperate with a verifier secretly to achieve special interests. So the verifier needs to identify the signer...

Traditional covert channels study mainly focus on digital signature, operation system and multimedia technology. The covert channels in TCP/IP protocol suite have many advantages, such as they are harder to be detected and more robust. Two covert channels are discovered by using FTP protocol command sequence based on the study of FTP protocol. The...
