Abstract: A public key may be recorded on the blockchain by a certificate authority in such a manner that any third party may quickly and easily verify that the public key is certified by the certificate authority and that the certification has not been revoked. The certificate authority may be able to revoke the certification nearly instantaneously, and/or may be able to simultaneously certify a new key for the same entity while revoking the old key. The verification may be incorporated into a new transaction so that there is no gap between reliance on the certificate and the verification of its validity. In some cases, each transaction in which the certificate is used may also serve as linked certificate transaction that renews the certificate to enable a subsequent use.

Abstract: Point cloud coding methods, an encoder, and a decoder are provided. The method includes the following. Morton codes for a point cloud are obtained according to geometry information of the point cloud after geometry decoding is completed and the geometry information is reconstructed. The point cloud is determined as an input point cloud of an iteration. Morton codes for an input point cloud of an i-th iteration are right shifted by K bits according to a number of points in the input point cloud of the i-th iteration, where K is a positive integer. A point is selected from points with a same value of Morton codes after right shifted by K bits. An i-th level of detail (LOD) layer is formed with the point selected. Color information is decoded according to the LOD layer.

Abstract: Systems and methods for automatically building up a VPN to facilitate full-mesh communication within an enterprise based on group and role settings of the participating network devices are provided. An SDWAN controller associated with a private network receives configuration information related to group setting and role setting for various network devices of the private network. The group setting indicates a group with which a network device is associated and the role setting specifies a role of the network device within the group as of either a hub or an edge. The SDWAN controller determines IPsec configuration information for generating VPN links between the network devices of the groups to enable full-mesh communication among the groups. The SDWAN controller further directs the network devices to set up IPsec tunnels by pushing the determined IPsec configuration information to the network devices.

Abstract: Systems and methods are described for automatically building up a VPN to facilitate full-mesh communication within a private network of an organization based on group and role settings of participating network devices. According to one embodiment, configuration information, including a group setting, indicating a group with which the particular network device is associated, and a role setting, specifying a role of the particular network device within the group as either a hub or an edge, is received by an SDWAN controller associated with the private network for each network device of the private network. Based on the configuration information, IPsec configuration information is determined for establishment of VPN links between a hub of each group and one or more edges of the group. Full-mesh communication among the groups is enabled by causing the hubs to set up IPsec tunnels between each pair of hubs based on the IPsec configuration information.

Abstract: A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.
