In telecommunications, message switching was the precursor of packet switching, where messages were routed in their entirety, one hop at a time. It was first built by Collins Radio Company, Newport Beach, California, during the period 1959–1963 for sale to large airlines, banks and railroads. Message switching systems are nowadays mostly implemented over packet-switched or circuit-switched data networks. Each message is treated as a separate entity. Each message contains addressing information, and at each switch this information is read and the transfer path to the next switch is decided. Depending on network conditions, a conversation of several messages may not be transferred over the same path. Each message is stored (usually on hard drive due to RAM limitations) before being transmitted to the next switch. Because of this it is also known as a 'store-and-forward' network. Email is a common application for message switching. A delay in delivering email is allowed, unlike real-time data transfer between two computers.
Method and system for fast positioning of a vehicle with a door lock
PendingCN122179895ARoad vehicles traffic controlParticular environment based servicesTopology informationLocation tracking
This invention discloses a method and system for rapid vehicle location tracking via door locks. The method includes: configuring topology information containing neighboring door lock addresses for each unit door lock based on a preset community access topology map; the resident door lock sending an IGMP join message to a preset multicast address; generating a discovery message based on the first detection of a Bluetooth tag signal by the unit door lock, and forwarding it to predicted neighbors via unicast according to the neighbor topology; the unit door lock receiving the discovery message switching its Bluetooth detection mode from low frequency to high frequency, forming a relay detection chain along the predicted path; and, based on the condition that the tag's signal strength remains stable near a certain unit door lock, generating a formal announcement multicast message, which is then forwarded by a router to the corresponding resident door lock, completing the vehicle location push. Using this invention, rapid, accurate, and low-power vehicle Bluetooth tag location can be achieved, improving the location response speed and system coordination efficiency in a community environment.

Authentication response verification using qubits and quantum channel
ActiveUS12665772B2Key distribution for secure communicationUser identity/authority verificationEngineeringMessage switching
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.

Device, method and system for communication between devices in the absence of time synchronization
A method, system, and device for secure communication in environments without synchronized clocks. Using a clock-skew server, devices embed clock-skew certificates in MIKEY-SAKKE messages to compute and verify message generation times. These certificates facilitate secure message exchange, including peer-to-peer scenarios and applications requiring intermediary servers, by addressing clock drift without relying on external time references. Embodiments support mission-critical communication while mitigating replay attacks and resource inefficiencies inherent in traditional synchronization-dependent methods.

Collective remote attestation framework
PCT designated stageWO2026106866A1Key distribution for secure communicationMultiple keys/algorithms usageInternet privacyEngineering
Disclosed are methods and systems for verifying the integrity of sensor device programs within a distributed network through secure message exchanges using a unidirectional keychain and cryptographic techniques. A verifier device communicates with sensor devices by broadcasting sequential messages containing nonces, keys, and encrypted attestation requests. Sensor devices authenticate received keys, derive encryption keys, decrypt attestation instructions, compute hashes of locally stored programs, and compare computed message authentication codes to determine trust status. When devices and / or programs are determined to be not trusted, corrective actions for devices may be initiated.

Mailbox message exchange between daisy-chained nodes in a synchronous communication network
A communication system includes a plurality of nodes connected in a daisy-chain via respective bus links configured for full duplex, synchronized communication. A node is configured to communicate a mailbox message with one or more connected nodes, the mailbox message having a flexible message size or flexible destination defined based on register access. A node includes a mailbox register configured to store a message header and one or more words of a current message for one or both of a transmit direction or a receive direction. The node includes a message buffer configured to store one or more messages including the current message for transmission or reception. The node includes a tunnel controller configured to communicate the current message from or to the message buffer as one or more mailbox packets with one or more of the connected nodes that participate in a mailbox tunnel over the daisy-chain.
