Abstract

It is provided a method for providing access to a physical space secured by a lock for provision of a service. The method comprises the steps of: receiving an approval signal from a service consumer device of the service consumer, the approval signal indicating that the service consumer allows a service provider agent of a service provider to open the lock; receiving, from the service provider device, a request to assign a service provider agent to open the lock; communicating with the service provider device to use a private key of a cryptographic key pair accessible to the service provider device, the private key being used to generate service agent access data that is specific for the service provider agent, to allow the service provider agent to open the lock; and transmitting the service agent access data to a service provider agent device associated with the service provider agent.
