The application relates to subscription-notification mechanisms for synchronization of distributed states. The invention provides an apparatus, systems, methods, and related computer program productsfor synchronizing distributed states amongst a plurality of entities and authenticating devices to access information and/or services provided by a remote server. Synchronization techniques include client devices and remote servers storing buckets of information. The client device sends a subscription request to the remote serve identifying a bucket of information and, when the bucket changes, theremote server sends the change to the client device. Authentication techniques include client devices including unique default credentials that, when presented to a remote server, provide limited access to the server. The client device may obtain assigned credentials that, when presented to the remote server, provide less limited access to the server. 本申请涉及用于分布式状态的同步的订阅通知机制。本发明提供了用于使在多个实体之间的分布状态同步以及认证设备以访问远程服务器所提供的信息和/或服务
