Aiming at the authentication of civilian signals broadcasted by currently orbiting GPS satellites, this paper proposes a new technique, which carries GPS authentication information by the messages hidden in the navigation message and, without affecti

The GPS system is capable of one-way communication (OWC) if the reserved bits of navigation message are utilized. Excluding the potential communication protocol overheads, a single frequency with one satellite transmits data at 0.5B/s; with the dual

There are two main techniques to disable GPS user receivers from performing navigation fix, either causing interference on transmission route segment or using directional signal radiation on satelliet segment. This paper introduces a new Denial of Se

In collaborative environment the threshold structure is common for joint authorization. Although with the powerful ability to enforce security policies, traditional RBAC hardly considers the issue. In order to solve the problem, we describe the thres

The ports which are often open on different hosts at different times are extremely important for network security analyses because they supply more attack chances to attackers. These ports can be discovered by sequential port scans. For network defen
