Provided is a process, including: accessing, with a processor of an embedded computing device, immutable executable code stored in read-only memory of the embedded computing device; executing, with the processor of the embedded computing device, instructions of the immutable executable code that retrieve, from the read-only memory, a network-layer address of a tamper-evident, immutable data repository and an application-layer address of firmware of the embedded computing device stored in the tamper-evident, immutable data repository; executing, with the processor of the embedded computing device, instructions of the immutable executable code that, using the network-layer address and the application-layer address, download the firmware of the embedded computing device from the tamper-evident, immutable data repository; and executing, with the processor of the embedded computing device, instructions of the immutable executable code that store the downloaded firmware in re-writeable memory of the embedded computing device.

An example method comprises receiving a number of inputs to a system employing an artificial neural network (ANN), wherein the ANN comprises a number of ANN partitions each having respective weight matrix data and bias data corresponding thereto stored in a memory. The method includes: determining an ANN partition to which the number of inputs correspond, reading, from the memory the weight matrix data and bias data corresponding to the determined ANN partition, and a first cryptographic code corresponding to the determined ANN partition; generating, using the weight matrix data and bias data read from the memory, a second cryptographic code corresponding to the determined ANN partition; determining whether the first cryptographic code and the second cryptographic code match; and responsive to determining a mismatch between the first cryptographic code and the second cryptographic code, issuing an indication of the mismatch to a controller of the system.

Secure emergency vehicular communication is described herein. An example apparatus can include a processing resource, a memory having instructions executable by the processing resource, and an emergency communication component coupled to the processing resource. The emergency communication component can be configured to generate an emergency private key and an emergency public key in response to being within a particular proximity from a vehicular communication component associated with a vehicular entity and in response to receiving a vehicular public key from the vehicular communication component. The emergency communication component can be configured to provide the emergency public key, an emergency signature, and notification data to the vehicular communication component.

Disclosed herein are techniques for using a line-of-code behavior and relation model to determine software functionality changes. Techniques include identifying a first portion of executable code and a second portion of executable code; accessing a first line-of-code behavior and relation model representing execution of functions of the first portion of executable code; constructing, based on the second portion of executable code, a second line-of-code behavior and relation model representing execution of functions of the second portion of executable code; performing a functional differential comparison of the first line-of-code behavior and relation model to the second line-of-code behavior and relation model; determining, based on the functional differential comparison, a status of functional equivalence between the first portion of executable code and the code portion of executable code; and generating, based on the determined difference, a report identifying the status of functional equivalence.

Various embodiments are generally directed to providing authentication and confidentiality mechanisms for message communication over an in-vehicle network. For example, authentication data associated with a communicating node may be transmitted over the network by encoding different predefined voltage levels on top of the message bits of the message being communicated. Different voltage levels may represent different encodings, such as a bit-pair or any bit combination of the authentication data. In a further example, messaging confidentiality between at least two communicating nodes may be achieved by pseudo-randomly flipping, or scrambling, the dominant and recessive voltages of the entire message frame at the analog level based on a pseudo-random control bit sequence.

A parking system having parking lots and server computers configured to control access to the parking lots. The server computers are connected via a communications network to form a peer to peer network of computing nodes. The peer to peer network of computing nodes hosts a decentralized, distributed database that stores activity records of parking spaces in the parking lots. The peer to peer network can include vehicles planning to use parking services of the parking lots and/or mobile devices connected to infotainment systems of the vehicles. Alternatively, the peer to peer network is formed by parking applications running in the vehicles and/or the mobile devices. The records in the decentralized, distributed database provide parking space availability information and/or can be used to regulate and/or plan parking reservation, usage, and navigational guidance to reach available parking spaces.

The present disclosure describe methods, apparatuses, storage media, and systems for a device disposed at an edge of a vehicular communication network or vehicles within a coverage area of the device. The device is to generate a list of vehicle security data to be distributed to vehicles currently within a coverage area of the device, based at least in part on a context related to the vehicles. The device is further to announce, on a control channel communicatively coupling the device and the vehicles, that the list of vehicle security data are available and a service channel to receive the list of vehicle security data. The list of vehicle security data are to be provided to the vehicles via the service channel. Other embodiments may be described and claimed.

The present embodiments relate to systems and methods for using a blockchain to record information related to the lifecycle of a vehicle associated with a Vehicle Identification Number (VIN). For example, the VIN lifecycle process may be used to develop safety-feature based insurance models. The systems and methods may include calculating a safety rating for a safety feature based upon data accessed at a blockchain. The safety rating may be used to generate a product associated with a new vehicle type, such as an insurance product covering the new vehicle type. The systems and methods described herein may allow for using a blockchain which gives the option for private information, and permissioned participants in the blockchain. In particular, the systems and methods may allow for a distributed consensus amongst businesses, consumers, and authorities, as to the validity of information and transactions stored on the blockchain.

Methods and systems of segmenting computing devices in a wireless network having an access point broadcasting in a single domain are described. In an exemplary method, a request to join the wireless network is received from a computing device. The request is associated with an identifier. When the identifier is not associated with a virtual network within the wireless network, a virtual network is configured within the wireless network and the identifier is associated thereto and the computing device is assigned thereto. When the identifier is associated with an existing virtual network within the wireless network, the computing device is assigned to the existing virtual network.

Systems and methods for cloud-based keyless entry are generally described. In some examples, a first number is received from a vehicle. A first computing device of the vehicle may be configured to control an electronic door lock. A first unlock code may be generated using the first number. In some examples, a notification is sent to a remote entry device associated with the vehicle. A response to the notification may be received from the remote entry device. In some examples, the first number may be retrieved from a messaging service based at least in part on the receiving the response to the notification. A second unlock code may be generated using the first number. A determination may be made that the first unlock code matches the second unlock code. An instruction may be sent to the first computing device, the instruction effective to cause unlock of the electronic door lock.
