A device, method and system for changing communication infrastructure based on call security level is provided. A device determines a call security level of a call occurring at a first communication infrastructure; the first communication infrastructure associated with a first security level; the call security level determined from one or more of; a profile of a caller on the call; and audio on the call. In response to determining that the call security level and the first security level are misaligned, the device causes the call to change to a second communication infrastructure associated with a second security level aligned with the call security level.

A management electronic device includes a processing circuit configured to: obtain a spectrum in an N-th round of spectrum trading and acquire the interference received by the management electronic device when an electronic device uses the traded spectrum; receive the interference received by another electronic device as determined by another electronic device related to spectrum trading; determine competition rights parameters of the management electronic device and the other electronic device, respectively, the competition rights parameters representing the credibility of the electronic devices and the magnitude of competitiveness when competing for management rights in an N+1-th round of spectrum trading; and select a new management electronic device on the basis of at least one among the interference and the competition rights parameters, the new management electronic device having management rights in the N+1-th round of spectrum trading, instead of the management electronic device having management rights.

Various embodiments provide methods, vehicle computing devices, storage media, and systems for briefly providing PathHistory information in Broadcast Safety Messages (BSMs) sent from a vehicle when PathHistory information is not required to be included in all BSMs. Various embodiments may include broadcasting BSMs including PathHistory information during a period of time following a change of the vehicle's pseudonym certificate and broadcasting BSMs without PathHistory information at all other times. Some embodiments may further include determining whether sufficient path history points are available for PathHistory information generation, accumulating path history points in response to determining that sufficient path history points are not available for PathHistory information generation, and broadcasting BSMs including PathHistory information during the period of time once sufficient path history points have been accumulated.

Embodiments of this application provide a Bluetooth connection method, a system, and an electronic device. In the method, when a communication connection between an electronic device and a vehicle head unit is disconnected, the electronic device starts to scan a Bluetooth advertising signal. When a user carrying the electronic device is close to the vehicle head unit, the electronic device may obtain, through scanning, a Bluetooth advertising signal sent by the vehicle head unit. When obtaining, through scanning, the Bluetooth advertising signal sent by the vehicle head unit, the electronic device may start a vehicle manufacturer application when the vehicle manufacturer application is cleared by a system. The electronic device may reconnect to the vehicle head unit through Bluetooth by using the vehicle manufacturer application and a Bluetooth chip. Embodiments of this application can improve convenience of unlocking in a scenario in which a vehicle is insensibly unlocked.

A messaging system for exchanging messages between nodes in a network via a broker that uses a publish-subscribe message protocol, which nodes have object identifications (IDs). Messages between the nodes are routed using the object IDs of the nodes. Secure communication is provided using authentication according to digital certificates being used as first and second tiers by a commissioning broker and a data broker, respectively, in which the second tier certificate used by the data broker has a shorter lived expiration time.

The present invention provides a wireless communication method of an access point. The wireless communication method comprises the steps of: establishing a cache table comprising a plurality of reference MAC and corresponding PMKs and reference PMKIDs; receiving an association request from a station; reading a MAC address of the station and a PMKID from the association request; if the MAC address of the station and the PMKID do not match items of the cache table, performing a calculation on the PMKID to obtain an original PMKID; determining if the original PMKID matches any one of the reference PMKIDs within the cache table; and if the original PMKID matches one reference PMKID within the cache table, determining that the reference MAC recorded in the cache table and the MAC address belong to the same station.

Systems and methods for a security network integrating security system and network devices are disclosed. A system may comprise a gateway and first and second security panels, each located at a premises. The first and second security panels may be connected, via respective first and second wireless communication protocols, to respective first and second security system components. The first and second security panels may receive respective first and second security data from the respective first and second security system components. The gateway may be configured to receive, via the first and second wireless communication protocols, the respective first and second security data. The gateway may be configured to transmit at least one of the first security data and the second security data to a security server located external to the premises.

Aspects described herein may allow for determining network membership to facilitate detecting fraudulent messages. A computing device may receive, from one or more terminals at a first location, a plurality of interactive messages during a pre-determined time period. Each interactive message may comprise personally identifiable information of a user. The computing device may store a first record and a second record that indicate interactive messages were received from a group of users in temporal proximity to each other at the first location and the second location respectively. The computing device may send a request to confirm users in the subset are members of a network and update a membership list based on a reply received from the user. If further messages are received from devices outside the membership list, an alert may be sent to alert the possibility of a fraudulent message.

A method is disclosed. The method includes receiving a broadcast signal from a beacon device, the broadcast signal encoding a first credential associated with a first entity. In response to receipt of the broadcast signal, the mobile communication device transmits the received first credential to an authentication system. The authentication system determines if the first entity associated with the broadcast signal is authentic and generates a confirmation message confirming the authenticity of the first entity. The mobile communication device then receives the confirmation message indicating that the first entity is authentic. The mobile communication thereafter receives and transmits a second credential for the mobile communication device to the beacon device, which transmits the second credential to the authentication system. The authentication system then confirms the authenticity of the mobile communication device. Then, the beacon device can initiate an interaction process with the user of the mobile communication device.
