Publication number: US20220182375A1
Application number: 17/544,935

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.

Publication number: US20220191125A1
Application number: 17/543,726

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.

Application number: 17/541,650

A polymer solar cell includes a photoactive layer, a cathode electrode, and an anode electrode. The photoactive layer includes a polymer layer and a carbon nanotube layer. The polymer layer includes a first polymer surface and a second polymer surface opposite to the first polymer surface. A portion of the carbon nanotube layer is embedded in the polymer layer, and another portion of the carbon nanotube layer is exposed from the polymer layer. The cathode electrode is located a surface of the carbon nanotube layer away from the polymer layer. The anode electrode is located on the first polymer surface and spaced apart from the carbon nanotube layer. The entire second polymer surface is exposed.
