An unmanned aerial vehicle (UAV) receives a set of Random Access preambles, determines its UAV status, and selects a Random Access preamble from the set of Random Access preambles. In some cases, the set of Random Access preambles are allocated for use by UAVs and are common to a plurality of neighboring cells. The UAV transmits the selected Random Access preamble to multiple neighboring cells.

Intermediary handling of identity services to guard against client side attack vectors
This document describes, among other things, security hardening techniques that guard against certain client-side attack vectors. These techniques generally involve the use of an intermediary that detects and handles identity service transactions on behalf of a client. In one embodiment, the intermediary establishes a resource domain session with the client in order to provide the client with desired resource domain content or services from a resource domain host. The intermediary detects when the resource domain host invokes a federated identity service as a condition of client access. The intermediary handles the identity transaction in the identity domain on behalf of the client within the client's resource domain session. Upon successful authentication and/or authorization with an IdP, the intermediary connects the results of the identity services domain transaction to the resource domain. |
