Current cellular architecture will not be suitable for 5G because it will not scale to the anticipated number of connected endpoints and their rich diversity. The distribution of the previously centralized Core Network (CN) functionality, e.g., Access Authentication and Authorization, has to be decentralized, leading to the demise of the most utilized tool of network security engineering, Physical Security Perimeter. The asserted and attested Platform Integrity of the network nodes that comprise the edges of the network, the network cloud, “network fog”, and the endpoints will allow mobile network operators (MNOs) to create Virtual Network Perimeters and allow highly reliable, diverse, and flexible 5G networks. This article describes the reasons for such network transformation, provides references to applicable standardization activities, and uses the examples of support for Unmanned Aerial Vehicles (UAV) and connected automobiles by 5G networks to justify the need for Platform Integrity.

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
