DEVICES, SYSTEMS, AND METHODS FOR MODIFYING AN ACCESS PERMISSION LEVEL

Abstract:

A server device that includes server elements that receive a modification request to modify a respective access permission level, designated to a client device for a target server element, from a baseline permission level among a permission hierarchy of access permission levels to a different permission level among the permission hierarchy. The server device sends a nonce associated with the modification request to the client device, and receives a signed nonce or nonce signature generated by the client device based on the nonce and a client private key of the client device. In response to determining an authenticity of the signed nonce or nonce signature based on a client public key that is associated with the client private key and trusted by the server device, the server device modifies the respective access permission level designated to the client device for the target server element to the requested permission level.
