A secondary processor device ownership assignment system includes a chassis that houses devices, a secondary processing system, a central processing system that includes an integrated switch device that is coupled to each of the devices and the secondary processing system, and a device ownership subsystem that is coupled to the central processing system. The device ownership system accesses device information for a subset of the devices that will be owned by the secondary processing system, and configures the device information for the subset of the devices such that the subset of the devices are hidden from an operating system provided by the central processing system. The secondary processing system reconfigures the device information for the subset of the plurality of devices such that the subset of the plurality of devices are accessible by the secondary processing system.

In accordance with an embodiment, an electronic device includes a secure element configured to implement a plurality of operating systems; and a near field communication module coupled to the secure element by a single bus and by a routing circuit configured to route routing data between the plurality of operating systems and a receive circuit of the near field communication module.

Security system for protecting a vehicle electronic system by selectively intervening in the communications path in order to prevent the arrival of malicious messages at ECUs, in particular at the safety critical ECUs. The security system includes a filter which prevents illegal messages sent by any system or device communicating over a vehicle communications bus from reaching their destination. The filter may, at its discretion according to preconfigured rules, send messages as is, block messages, change the content of the messages, request authentication or limit the rate such messages can be delivered, by buffering the messages and sending them only in preconfigured intervals.

Systems and methods for detection of attacks on a communication authentication layer of an in-vehicle network, including determining, by at least one network node, at least one attack attempt on the communication authentication layer of the in-vehicle network, wherein the determination is carried out by identifying anomalies in at least one of messages, data and metadata directed to the communication authentication layer, and selecting, by the at least one network node, a response corresponding to the determined attack attempt from at least one of modification of parameter values corresponding to a security protocol, a failsafe response, and rejection of messages identified as anomalies.

A method for detecting an unauthorized physical access to a bus system. The method includes detecting a test level sequence in the voltage signal; constituting a binary sampled pattern by sampling the voltage signal at specified pattern times associated with the detected test level sequence, and assigning a first value if the voltage signal is above a predefined voltage threshold at the respective pattern time, and a second value if the voltage signal is not above the voltage threshold; comparing the sampled pattern with a reference pattern that is associated with the detected test level sequence and that was constituted for the test level sequence as a sampled pattern in a state of the bus system during which no unauthorized access existed; and determining that a possible unauthorized physical access exists if the reference pattern does not match the sampled pattern.

A method of authorizing a limited use intravascular device can include determining if the intravascular device is in communication with a clinical system; determining if the intravascular device is authorized for clinical operation without providing the clinical system access to intravascular device data stored on the intravascular device; and providing an authorization signal to the clinical system. An intravascular device can include a flexible elongate member including a sensing component at a distal portion and a connector at a proximal portion, the connector including: a memory component configured to store a parameter value; a processing component; and a charge storage component configured to power the memory component and/or the processing component; wherein the processing component is configured to determine if the flexible elongate member is authorized for clinical operation using the parameter value without providing the parameter value to a clinical system.
