Methods, systems and computer program products which provide secure updates of firmware (i.e. data stored in a programmable memory device of a processing system) are disclosed. Updates of a programmable memory of a device may be controlled by providing an update window of finite duration during which the programmable memory may be updated. Access to the programmable memory may be based on the state of an access latch. The access latch may be set to allow access after a hardware reset of the device. An update control program may be executed to control access to the programmable memory and the latch reset to prevent access upon completion of the update control program. Verification of the update may be provided through encryption techniques and rules incorporated in certificates for application of updates to provide for selectively updating devices. Also disclosed are methods of securely providing differing functionality to generic devices.

The method disclosed herein provides for performing device security corrective action based on loss of proximity to another device, such as a key device. While a mobile communication device is locked, a mobile communication device determines whether or not a key device is within a specified distance. If the key device is not within the specified distance from the mobile communication device, a notification may be displayed on the mobile communication device. If a user responds to the notification, the user may prevent or alter the mobile communication device from performing at least one device security corrective action. If, however, the user does not respond to the notification within a specified time period, the at least one device security corrective action is performed on the mobile communication device.

A method and system for enhancing computer peripheral safety is provided. In accordance with various aspects of the present invention, the exemplary method and system are configured to monitor and / or isolate alternating current (A.C.) supplies with and / or from any peripheral subsystems or devices. An exemplary method and system comprises an A.C. supply, a host computer system, and a peripheral subsystem or device connected to the host computer system, such as an ultrasound imaging and / or therapy peripheral, and an isolation subsystem configured for monitoring and / or isolating the A.C. supply from the peripheral subsystem or device. In accordance with an exemplary embodiment, an isolation subsystem comprises application software and associated modules and functions that when executed continuously monitors and / or polls the host computer's hardware and / or operating system for the presence of an isolated source, such as a battery, or an unisolated power source, such as through a battery charger and / or other connection path to the A.C. main supply. In accordance with other exemplary embodiments, an isolation subsystem can comprises a wireless or other safe / isolated electrical link for connecting a patient contact device, and / or a verification link or other verification mechanisms configured between an isolation transformer and host computer to monitor or observe usage to power the host computer and peripheral subsystem.

A portable encryption key installation system is disclosed that includes a portable keying device for installing a data communications encryption key in an electronic terminal. The portable keying device securely reprograms the encryption key in the electronic terminal without having to remove the terminal from its shipping container or ship the electronic terminal offsite. Furthermore, the portable keying device securely reprograms the encryption key in the electronic terminal without having to dismantle the terminal, deactivate any anti-tampering features, or re-bond the terminal.

A security token access device, a user device such as a computing device or communications device, and a method for managing multiple connections between multiple user devices and the access device. The access device maintains connection information, including security information, for each user device securely paired with the access device. Each time a new user device is paired with the access device, the access device transmits a notification to the user devices already paired to the user device. A user may provide instructions to the access device to terminate a pairing with one of the user devices by overwriting at least a portion of the connection information associated with the designated user device. A user device may further request a listing of all user devices currently paired with the access device.

An ignition device for a downhole tool includes a body with a cavity, a thermite material and a resistive element within the cavity. The resistive element, which is heated to the high temperature needed for ignition of the thermite material, has a non-galvanic outer surface at the ignition temperature. A large amount of electrical power is required to reach the ignition temperature, making the device safe and unlikely to accidentally ignite. The device has an electrical connector that is located within a sealed chamber when downhole.

A system and method for securing data in mobile devices (104) includes a computing mode (102) and a plurality of mobile devices (104). A node security program (202) executed in the computing node (102) interfaces with a device security program (204) executed at a mobile device (104). The computing node (102) is responsible for managing the security based on a node security profile (208) interpreted by a node security program (202) executed in the computing node (102). A device discovery method and arrangement (106) also detects and locates various information (120) about the mobile devices (104) based on a scan profile (206).

A trust web keying process provides secure peer networking of computing devices on an open network. A device is initially keyed at distribution to an end user or installer with a device-specific cryptographic key, and programmed to respond only to peer networking communication secured using the device's key. The device-specific key is manually entered into a keying device that transmits a re-keying command secured with the device-specific key to the device for re-keying the device with a group cryptographic key. The device then securely peer networks with other devices also keyed with the group cryptographic key, forming a trust web. Guest devices can be securely peer networked with the trust web devices via a trust web gateway.
