Abstract: A system and method for cryptographically securing data communications between a group of networked devices establishes and maintains an overlay network at the Application Layer, on top of a unicast routing service provided at the Internetworking Layer. The overlay network provides first, the routes that are used to deliver multicast datagrams and second, the cryptographic keys used to secure multicast datagrams. A common cryptographic key is established between all members of each group, and end-to-end encryption ensures that multicast datagrams can be accessed only by authorized group members. In other embodiments, keys are established between pairs of adjacent devices in the overlay network, and hop-by-hop encryption ensures that multicast datagrams can be accessed only by overlay network members.

Abstract: Various embodiments of the present disclosure relate to folding furniture, and more specifically, to folding chairs with the ability to support their own weight and stand while in a folded position. In an embodiment, a folding chair configurable in an unfolded position and a folded position comprises a first leg assembly, a second leg assembly, a seat, and a chair back fixed between the first and second leg assemblies. The first and second leg assemblies each comprise an outer leg pivotally coupled with an inner leg, such that in the folded or unfolded positions, the first and second leg assemblies support the folding chair. The seat comprises a support bar and is pivotally coupled with each inner leg of the first and second leg assemblies, such that in the unfolded position, the seat provides support for a person when the support bar contacts a portion of the first outer leg and a portion of the second outer leg preventing overextension of the seat.
