TL;DR: A new, general mechanism, called packet leashes, is presented for detecting and thus defending against wormhole attacks, and a specific protocol is presented, called TIK, that implements leashes.
Abstract: As mobile ad hoc network applications are deployed, security emerges as a central requirement. In this paper, we introduce the wormhole attack, a severe attack in ad hoc networks that is particularly challenging to defend against. The wormhole attack is possible even if the attacker has not compromised any hosts, and even if all communication provides authenticity and confidentiality. In the wormhole attack, an attacker records packets (or bits) at one location in the network, tunnels them (possibly selectively) to another location, and retransmits them there into the network. The wormhole attack can form a serious threat in wireless networks, especially against many ad hoc network routing protocols and location-based wireless security systems. For example, most existing ad hoc network routing protocols, without some mechanism to defend against the wormhole attack, would be unable to find routes longer than one or two hops, severely disrupting communication. We present a new, general mechanism, called packet leashes, for detecting and thus defending against wormhole attacks, and we present a specific protocol, called TIK, that implements leashes.
TL;DR: In this article, a method, system, transmitter, receiver and protocol for communicating with wireless receivers is described, which includes a controller having a discovery mode and an operating mode, in the discovery mode the controller is capable of registering wireless devices and in the operating mode it can receive transmissions from a wireless device that has been registered.
Abstract: A method, system, transmitter, receiver and protocol are disclosed for communicating with wireless receivers. The invention includes providing a controller having a discovery mode and an operating mode, in the discovery mode the controller is capable of registering wireless devices, in the operating mode the controller is capable of receiving transmissions from a wireless device that has been registered. A wireless transmitter is provided which is capable of communicating wirelessly with the controller. The wireless device has an actuator for initiating at least one transmission of registration data. When the controller is placed into the discovery mode, and the actuator of the wireless device is actuated to wirelessly transmit the registration data from the wireless device to the controller, whereby the wireless device is registered with the controller. The wireless data contains data that allows the controller to interface with the wireless device.
TL;DR: In this paper, a system and method for enabling a zero configuration nomadic wireless and wired computing environment presenting a just works experience is presented, which examines predefined user preference or profile settings to determine to which of a competing number of wireless networks available it should connect, and what type of authentication should be used for such connection.
Abstract: A system and method for enabling a zero configuration nomadic wireless and wired computing environment presenting a just works experience is presented. The system examines predefined user preference or profile settings to determine to which of a competing number of wireless networks available it should connect, and what type of authentication should be used for such connection. Nomadic wireless computing between infrastructure wireless networks and ad hoc wireless networks may be accomplished without further user intervention required in an auto mode. Also, both infrastructure only and ad hoc only modes are available through the system of the invention. Further, the user may set a preference for infrastructure or ad hoc modes in the auto mode. With an infrastructure mode preference set, the system will automatically detect and transfer connectivity to a newly available infrastructure wireless network if the user was previously operating off-line or in ad hoc mode.
TL;DR: In this article, the authors present a system for automatically monitoring and controlling the actual speed of a vehicle relative to the legal speed limit of the geographic area the vehicle is located in.
Abstract: A system ( 12 ) and method for automatically monitoring and/or controlling the actual speed of a vehicle ( 10 ) relative to the legal speed limit of the geographic area the vehicle is located in. A wireless transmission ( 32 ) containing location or legal speed limit information is received from a transmission source ( 24 ). If location information is obtained, database ( 40 ) is queried to obtain legal speed limit information for the physical location of the vehicle. The legal speed limit is stored into a memory space ( 36 ). Alternatively, the legal speed limit is used to control the actual speed of the vehicle. In a monitor mode, the system ( 12 ) compares the actual speed of the vehicle to the legal speed limit with a processor ( 37 ), and the relative information may be communicated to the driver. In an offset mode, the system ( 12 ) controls the actual speed of the vehicle to an offset amount relative to the legal speed limit, where the offset amount is set by the driver of the vehicle. The transmission source ( 24 ) may be a GPS-compatible satellite network ( 30 ) or a transmitter ( 28 ) on a traffic sign ( 26 ).
TL;DR: In this article, a data processing system including a processor operable in a plurality of modes and in either a secure domain or a non-secure domain is defined, and the processor is operable at least partially in the monitor mode to execute a monitor program managing switching between the secure and nonsecure modes.
Abstract: A data processing system including a processor operable in a plurality of modes and in either a secure domain or a non-secure domain. The system includes at least one secure mode being a mode in the secure domain, at least one non-secure mode being a mode in the non-secure domain, and a monitor mode. When the processor is executing a program in a secure mode the program has access to secure data which is not accessible when the processor is operating in a non-secure mode. Switching between the secure and non-secure modes takes place via the monitor mode and the processor is operable at least partially in the monitor mode to execute a monitor program managing switching between the secure and non-secure modes.
