Abstract

It is presented a method for providing access to a lock for provision of a service. The method comprises the steps of: receiving a request for access to the lock, the request being based on the service consumer ordering a service requiring access to a physical space, the request comprising a first public key associated with a co-ordinator and a second public key associated with a service provider agent; presenting a first consumer query to the service consumer; receiving a first positive consumer response indicating that the service consumer allows the service provider agent to access the physical space; and delegating access to the lock to the co-ordinator, which comprises encrypting at least part of a delegation using the first public key, encrypting at least part of the delegation using the second public key, and electronically signing the delegation, enabling further delegation to the service provider agent.
