Abstract: An atomic ability invoking method includes a terminal device obtaining an invoking request of an app for an atomic ability (A/A). When the AA is deployed in the terminal device, the terminal device starts the AA and grants, to the AA, a resource access permission required by the AA, so that the AA responds to the invoking request based on the resource access permission required by the AA. According to this method, in a process in which the app invokes the AA, the AA has only the resource access permission required by the AA, to prevent the AA from accessing a corresponding system resource based on a resource access permission that the AA should not have.

Abstract: A method of load sharing, includes: extracting a factor field capable of distinguishing data flow in a packet header of the classified data flow, and taking the factor field as an input factor of a default load sharing algorithm of a network forwarding device interface, or taking the factor field as an input factor of a load sharing algorithm capable of uniformly allocating the data flows and selected according to the flow characteristic of the data flows, calculating the paths of the data flows, and forwarding the data flows according to respective paths. The method is used for increasing the expansibility of the network forwarding device and achieving load balancing.

Abstract: This application discloses a distributed denial of service attack detection method. The method includes: obtaining a data stream sent to a protection object device in each detection period, obtaining total duration of each data stream; dividing each data stream into a long data stream or a short data stream based on the total duration of each data stream; adding, based on a detection period through which the long data stream goes, total data traffic of the long data stream to statistical traffic; adding data traffic of a short data stream in each detection period to the data traffic, of the long data stream, that is added to a corresponding detection period, to determine statistical traffic in each detection period; and if there is a detection period in which the statistical traffic exceeds a preset traffic threshold, determining that the protection object device undergoes a DDoS attack in the detection period.

Abstract: A key negotiation method and an electronic device are provided, and relate to the field of communications technologies. Specifically, the method includes: An IoT control device multicasts, in a first local area network, a discovery message that carries a first public key, and sends a second ciphertext to a first IoT device after receiving a first ciphertext and a second public key. After receiving a third ciphertext from the first IoT device, the IoT control device decrypts the third ciphertext based on a first session key, to obtain a second signature and second session information; verifies the second signature based on a long-term public key of the first IoT device; and performs encrypted communication with the first IoT device based on the first session key after the second signature is successfully verified.
