Abstract
Provided is a management server system that accepts a transition instruction for transition between tenants of an agent device, generates symmetric keys consisting of a first key and a second key, responds the second key to the agent device, and verifies signature information included in a transition request using the first key when the agent device makes a tenant transition request. Upon successful verification of signature information, the management server system transmits new authentication information for communication between the management server system and the agent device to the agent device. After transition of the tenant, the agent device communicates with the management server system using the new authentication information.
