The systems and methods balance privacy and efficiency by distributing activation codes according to various approaches, including a direct request approach, a fixed-size subset approach, and a variable-size subset approach.

A peer-to-peer offline communication method, including: at a mobile device executing a mobile device communication application, generating a mobile device certificate signing request and sending the mobile device certificate signing request to a cloud server; at the mobile device communication application, receiving a signed mobile device certificate from the cloud server; at a vehicle executing a vehicle communication application, generating a vehicle certificate signing request and sending the vehicle certificate signing request to the cloud server; at the vehicle communication application, receiving a signed vehicle certificate from the cloud server; broadcasting the presence of the mobile device and discovering the presence of the mobile device at the vehicle; exchanging and verifying the signed certificate signing requests between the mobile device communication application and the vehicle communication application; and encrypting and decrypting data exchanged between the mobile device and the vehicle.

In one implementation, a method for automatically generating a security policy for a controller includes receiving, by a security policy generation system and from a controller development environment, code for a device controller; selecting middleware that enforces a security policy; analyzing the code for the device controller; based at least in part on the analyzing, automatically generating the security policy; and providing the selected middleware along with the generated security policy.

A secure chain of data blocks is maintained at a given computing node. The given computing node is part of a set of computing nodes in a distributed network of computing nodes wherein each of the set of computing nodes maintains the secure chain of data blocks. The secure chain of data blocks maintained at each computing node comprises one or more data blocks that represent one or more accident related transactions associated with a vehicle. In response to a risk assessment operation, one or more data blocks are added to the secure chain of data blocks maintained at the given computing node.

The present disclosure discloses a method for sharing models among autonomous vehicles based on a blockchain, the method comprising the steps of: 1) creating a mobile edge computing network; 2) generating a key pair for each node in the mobile edge computing network; 3) creating a local model set of a mobile node set in the mobile node computing network; 4) enabling each mobile node to communicate with a corresponding nearest mobile edge computing node; 5) creating supernode sequences by the mobile edge computing node; 6) creating a blockchain based on the supernode sequences; and 7) updating the local model set.

Disclosed herein is a vehicle theft prevention device. The device can include a data store including event configuration data. The device can include one or more sensors that can sense various types of measurements proximate to a vehicle. The device can include a computing device in communication with the sensors. The computing device can read measurements from the sensors and determine that a particular event has occurred. The computing device can analyze the measurements to determine the particular event occurred based on the event configuration data. When the particular event occurs, the computing device can perform one or more remedial actions.

In an authentication system, when an electrical component with a temporary ID recorded by a temporary ID assignment device is connected to a switching hub, a temporary authentication device performs temporary authentication based on switching hub information describing the switching hub to which the electrical component is connected, the temporary ID of the electrical component, and temporary authentication inquiry information. A main authentication device performs main authentication based on the switching hub information of the switching hub to which the electrical component with a formal ID recorded by the formal ID assignment device is connected, and the formal ID of the electrical component, and main authentication inquiry information.

An example operation may include one or more of receiving, by an accident processing node, an accident report from a transport, determining, by an accident processing node, a time and location parameters of the accident based on the report, querying, by an accident processing node, transport profiles on a storage based on the time and location parameters, and responsive to the transport profiles containing data corresponding to the time and location parameters, sending a request to access the transport profiles.

In one implementation, a method for automatically generating a security policy for a controller includes receiving, by a security policy generation system and from a controller development environment, code for a device controller; selecting middleware that enforces a security policy; analyzing the code for the device controller; based at least in part on the analyzing, automatically generating the security policy; and providing the selected middleware along with the generated security policy.

A method (100) for performing an authentication procedure between a verifying device and a responding device is disclosed, the verifying and responding devices being provisioned with security credentials. The method, performed by the verifying device, comprises generating an authentication challenge (110), delivering the authentication challenge to the responding device (120), receiving an authentication response from the responding device (130), and verifying the authentication response (140). According to the method, at least one of the authentication challenge or authentication response is encoded as a sequence of qubits and delivered over a quantum communication channel between the verifying device and the responding device (120A, 120B, 130A, 130B). Also disclosed are methods for delivering and receiving a message over a quantum communication channel, and devices for performing authentication and message exchange methods.
