Abstract: Embodiments described herein relate to apparatuses and methods for brewing tea via pods. The pods can be configured to work with existing pod-based espresso machines to build up pressure within the pod thereby enabling better brewing of teas (e.g., matcha, chai, etc.). The pods can have interlocking ribs or tabs configured to interface with the espresso machine to prevent leakage during the brewing process. The pods can be completely biodegradable (e.g., compostable). In some embodiments, the pods can include bilayer films/meshes disposed at the top and bottom of the body of the pod. In some embodiments, the bilayer films include non-woven PLA fabrics and papers with specific mesh sizes configured to allow the existing espresso machines to pierce the films and enable brewing of the teas. The tea powders (e.g., matcha powder) disposed within the pods have specific meshes to enable proper dispersion in water without agglomeration of the matcha particles in the finished beverage.

Abstract: The disclosure discloses an authentication method and system for a wireless mesh network. The method comprises: when a new node accesses a network and the node is a Mesh Point (MP), the MP selects one authenticated node from neighbor nodes as a father node, and a uniquely identified secure path exists between the father node and an AC; the MP uses the father node as an authentication point to perform authentication; and after being transmitted to the AC through the secure path between the father node and the AC, which then forwards an authentication message to an AS; similarly, a return message of the AS is forwarded by the AC to the father node through the secure path, and the MP is authenticated. The authentication message is saved on the AC at the same time, so as to facilitate the second authentication of the MP.
