Abstract: It is provided a method for controlling access to a physical space. The method is performed in an access control device and comprises the steps of: communicating with an electronic key to obtain an identity of the electronic key; obtaining a plurality of delegations; determining, from one of the delegations, that there is an auxiliary condition, wherein the auxiliary condition is that access is approved for the electronic key by an auxiliary party, authenticated by a digital signature by the auxiliary party; and granting access to the physical space when the plurality of delegations comprises a sequence of delegations covering a delegation path from the access control device to the electronic key such that, in the sequence of delegations, the delegator of the first delegation is the access control device, the receiver of the last delegation is the electronic key, and the auxiliary condition is fulfilled.

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.

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.

Abstract: It is provided a method for managing administration privileges of an electronic lock. The method is performed in the electronic lock and comprises the steps of: receiving a first signal from a first mobile device, the first signal comprising a first code entered by a user to the first mobile device, and an identifier of the first mobile device; determining that the first mobile device has administration privileges to the electronic lock; storing the first code in memory of the electronic lock; receiving a second signal from a second mobile device, the second signal comprising a second code entered by a user to the second mobile device, and an identifier of the second mobile device; and granting administration privileges to the lock for the second mobile device only when the second code matches the first code.

Abstract: According to a first aspect, it is provided 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; sending a consumer request to a service consumer device, asking whether to grant access to the lock; receiving a positive consumer response from the service consumer device; determining validity time for a grant token; obtaining a grant token for the service provider, the grant token having the determined validity time; providing the grant token to the service provider; deleting the grant token in the access coordination server; receiving an agent request for access to the lock for a specific service provider agent device, the agent request comprising the grant token; obtaining a credential for the service provider agent device; and providing the credential to the service provider agent device.
