Abstract: Methods and apparatuses are described for decentralized authorization of user access requests in a distributed service architecture. A gateway node receives a user access request from a remote computing device. The gateway generates a signed and encrypted access token based upon the user access request using an authorization service node and a key management service node. The gateway transmits the access token, the user access request, and a security certificate received from the authorization service to a security proxy node of a microservice container. The security proxy validates the certificate and the access token. The security proxy decrypts the access token using a public key from the certificate, and determines user authorization to access a service endpoint node based upon the decrypted token. The security proxy transmits the user access request to the service endpoint, which provides the remote device with access to services based upon the user access request.

Abstract: A distributed safety lockout system for a vehicle, such as a recreational vehicle (RV), that includes a plurality of networked devices communicatively coupled via a communications network, and that is configured to implement a method for controlling an electromechanical operation of an electromechanical device based on a safety lockout condition determined through use of a consensus protocol in which a safety lockout status is agreed upon by the networked devices. The safety lockout status may be escalated by a safety lockout condition detection device that detects a safety lockout condition, such as movement of the RV. The safety lockout status may be de-escalated through a network contention mode of the consensus protocol in which each of the networked devices agree to de-escalate the safety lockout status.
