A method for hierarchical Internet trust sharing includes dividing a network into intra-domain and inter-domain layers based on a management domain; performing authentication on a central certificate through a CA and publishing the central certificate to a blockchain; managing by the central node, a certificate of each communication node based on a real address; collecting by the central node, temporary data reported by each communication node every preset time interval, generating a trust evaluation value of each communication node based on the temporary data and forming a format file from the trust evaluation values; generating by the central node, a file digest from the format file at each preset time interval, and publishing the file digest verified by central nodes in the inter-domain to the blockchain; and automatically deleting by the blockchain, data from the time interval 1 to the time interval (N-T-1) to retain blockchain header information.

A method for selecting a recommended node in a behavior deviation model includes: determining a candidate path starting from a delegation node to a target node based on a preset network topology; determining candidate recommended nodes passing through each candidate path, and acquiring a first behavior deviation corresponding to the target node at each candidate node; reading a second behavior deviation of each candidate recommended node from a central node in the network topology; calculating an average deviation value for the target node based on second behavior deviations and first behavior deviations; determining a candidate path with the smallest average deviation value as a target candidate path; and in response to the average deviation value of the target candidate path being less than or equal to a preset warning value, determining the candidate recommended node on the target candidate path as a recommended node.

Method and device for selecting recommended node in behavior deviation model

Provided are keratin BD-4, an encoding nucleic acid molecule thereof, an expression vector, a host cell, and a pharmaceutical composition containing the keratin. The keratin BD-4 can be used for preparing drugs having antipyretic and analgesic, antitussive and expectorant, and antiepileptic effects.

The present disclosure relates to a component-based task allocation method for an extensible router, comprising: S1: selecting components that needs to be activated from a component library, generating a topology structure of the components, and measuring load of each component; S2: selecting a super master control and a backup super master control from master controls, allocating the components, generating a task allocation table and a task updating message according to dynamic allocation algorithms; and S3: receiving the task updating message from the super master control by the other master controls, and activating the components that need to be activated and registering to a component manager. Thus, the tasks can be allocated uniformly.
