Abstract: A hand-held pneumatic pollinator for hybrid rice seed production and a method thereof are provided. The pollinator includes a hand-held power chassis, a lifting assembly, a pneumatic pollination assembly, and a control assembly. A position of each of air blowing pipes relative to an ear of the male parent is adjusted by the control assembly and the lifting assembly. The pneumatic pollination assembly is provided with a plurality of air blowing pipes, of which the number is less than rows of the male parent of a hybrid rice seed production with a relatively large row ratio. Each air blowing pipe is located between corresponding two rows of the male parent during pollination. The directional, uniform and constant airflow at an air blowing port blows a pollen off a stamen to transport the pollen to the female parent compartment.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of secure network architecture. The method comprises transmitting, at a master device and to an access network device, a first level start-up request with a first identification signature corresponding to a first identification key for identifying the master device, the first identification key being generated based on a master key specific to the master device; receiving, from the access network device, a first level start-up authorization response with a first authorization signature corresponding to a second identification key; and verifying the first authorization signature with the first identification key.

Abstract: An example embodiment includes transmitting first connection information that the user device is connected to a plurality of servers to a first server, and receiving a list of candidate servers from the first server, the candidate servers being determined by the first server at least based on the first connection information. The embodiment further includes selecting a second server from the list to establish a connection.

Abstract: The present invention provides a solution of automatically distributing PIP keys, and on that basis, provides a new encryption method. A domain control device is proposed to verify whether a network node is an eligible node in the domain; if the network node is an eligible node in the domain, then a key for the PTP protocol is sent to the network node. The methods and apparatuses according to the present invention enable access authentication of various forms of PTP network nodes, as well as the automatic configuration and dynamic sending of PTP keys, such that the security of the keys are significantly increased. Additionally, by means of SignCryption encryption algorithm, it is enabled that for each PTP message, not only message source authentication, message integrity authentication, message confidentiality, and replay protection can be provided, but also its sending network node can be tracked. Thus, the security is significantly increased.

Abstract: The present invention provides a method for creating routes in access devices of the communication network by using access response messages. With the method provided by the present invention, services can be distinguished and forwarded based on destination IP sub-networks, so that different services can be distributed in access devices. In this way, on the premise that services are distinguished based on layer 3, the requirements for access devices are reduced and layer 2 networks on the user side are not required to carry out route protocols, which decreases administrators' maintenance work and is the important condition for the realization of plug&play and reduces the requirements for marginal routers.
