Abstract: Described is a data transmission method, comprising: a first terminal negotiating a shared key with a second terminal by means of a handshake message; and the first terminal transmitting application data to the second terminal by means of a content message, the content message being encrypted and decrypted by using the shared key, wherein the handshake message and the content message have the same message format, the message format comprises a message serial number and a message load, the message serial number comprises a key epoch identifier and a message seq identifier, and the key epoch identifier is characterized by bit information less than a first number of bits, and the message seq identifier is characterized by bit information less than a second number of bits.

Abstract: Device discovery methods, a first device, and a non-transitory computer-readable storage medium are provided. The method is performed by the first device and includes: interacting with a second device by means of n management frames, at least one of the n management frames including a customized field, and n being a positive integer; and acquiring device information of the second device based on a customized field in a first management frame. The first management frame is a management frame transmitted by the second device to the first device among the at least one of the n management frames.

Abstract: The present application relates to an information processing method and an electronic device. The method includes: broadcasting a first management frame, wherein the first management frame is configured for discovering a second device failing to access a network; and receiving a second management frame sent by the second device. The second management frame is configured for indicating that the second device requests networking information of a target network. The networking information is configured for the second device to use to access the target network.

Abstract: A device network configuration method and a first device are provided. The method is performed by the first device. The first device interacts with a second device through n management frames, at least one of the n management frames includes a vendor specific field, and the n is a positive integer. The method includes: broadcasting a first management frame without disconnecting a current communication connection, a vendor specific field of the first management frame carrying networking information of a first network, the networking information of the first network being configured to configure the second device to access the first network.

Abstract: Disclosed in the present application are a device authentication method and an electronic device. The device authentication method includes: establishing a first connection based on a TLS protocol between the electronic device and a first server; sending a first request to the first server on the basis of the first connection, the first request being used to request for identity authentication of the electronic device and generated on the basis of first information which represents a digital certificate of the electronic device; and on the basis of the first connection, receiving first response information about the first request, the first response information being sent by the first server and carrying a result of the identity authentication of the electronic device, and the identity authentication being performed by the first server.

Abstract: A data exchange method is applied to a first electronic device and includes receiving a first message sent by a second electronic device, wherein the first message carries a first identifier, the first identifier is configured to identify a first transaction to which the first message belongs, an active transaction indicates a transaction initiated by the first electronic device, and a passive transaction indicates a transaction initiated by the second electronic device; in a case where a set bit indicates that the first transaction is the active transaction, feeding a processing result about the first transaction in the first message back to an application layer; and in a case where the set bit indicates that the first transaction is the passive transaction, requesting the application layer to output the processing result about the first transaction based on the first message.

Abstract: – A network connection method is performed by a terminal, and the method comprises: establishing a pre-connection with a to-be-accessed device, and the to-be-accessed device being a device to access network; generating a first key pair, and sending a first public key In the first key pair to the to-be-accessed device; generating a first shared key based on the first key pair and first key negotiation information corresponding to the to-be-accessed device; encrypting network configuration information of a network device by using the first shared key, to obtain encrypted network configuration information; and sending the encrypted network configuration information to the to-be-accessed device, to allow the to-be-accessed device to decrypt the encrypted network configuration information by a second shared key, and access the network device based on the decrypted network configuration information.

Abstract: An account binding method, a control device, and a smart device are provided. The method includes the following. A request message is received from a control device, where the request message is for requesting a first string. The first string is generated according to a preset rule, where the first string and a master account logged in the control device have a mapping relationship. The first string is sent to the control device, where the first string is transferred by the control device to a smart device in a preset manner, and the first string is for the server to verify, according to the mapping relationship, validity of establishing a binding relationship between the smart device and the master account.

Abstract: A control method and apparatus for of an Internet of Things device, and an electronic device (110) are provided. The method includes: sending an action call to the IoT device, wherein the action call includes a target service instance identification (siid), a target instance identification (iid), and a property parameter.

Abstract: A data exchange method is applied to a first electronic device and includes receiving a first message sent by a second electronic device, wherein the first message carries a first identifier, the first identifier is configured to identify a first transaction to which the first message belongs, an active transaction indicates a transaction initiated by the first electronic device, and a passive transaction indicates a transaction initiated by the second electronic device; in a case where a set bit indicates that the first transaction is the active transaction, feeding a processing result about the first transaction in the first message back to an application layer; and in a case where the set bit indicates that the first transaction is the passive transaction, requesting the application layer to output the processing result about the first transaction based on the first message.
