Abstract: It is provided a method for determining when to trigger positioning of a portable key device used in access control for an electronic lock controlling access to a restricted physical space. The method is performed in a positioning determiner and comprises the steps of: obtaining movement data from a motion sensor of the portable key device, the movement data indicating movement of the portable key device; determining when the movement data indicates a stop in motion of the key device; and triggering positioning of the portable key device when a stop in motion of the key device has been determined.

Abstract: It is provided a method for controlling access to a physical space using an emergency delegation. The method is performed in a lock device and comprises the steps of: receiving an access request from an electronic key; obtaining a plurality of delegations, wherein each delegation is a delegation from a delegator to a delegatee, the plurality of delegations collectively forming a chain of delegations wherein when two delegations are chained together, the delegatee of one delegation is the delegator of the next delegation; determining that a delegation in the chain of delegations is an emergency delegation, the emergency delegation indicating that access should only be granted when an emergency situation occurs; determining when an emergency situation occurs; and granting access to the physical space when the chain of delegations starts in the lock device and ends in the electronic key; and when the emergency situation occurs.

Abstract: It is provided a method for determining whether a portable key device is located inside or outside a metal door. The method is performed by a credential communication device and comprises the steps of: obtaining a first time-of-flight, ToF, measurement between a first antenna and the portable key device, wherein the first antenna is located on the outside of the metal door; obtaining a second ToF measurement between a second antenna and the portable key device, wherein the second antenna is located on the inside of the metal door; and determining the portable key device to be located on the outside of the metal door when the first ToF measurement is less than the second ToF measurement by an amount which is greater than a threshold value.

Abstract: It is provided a method for determining when a portable key device is located on a front side or on a back side in relation to a barrier secured by an electronic lock. The method is performed in a location determiner and comprises the steps of: obtaining a channel impulse response, CIR, based on an impulse signal transmitted from the portable key device, the CIR being based on a plurality of samples of the impulse signal as received by an antenna being fixedly mounted in relation to the electronic lock; and determining, based on the CIR, whether the portable key device is located on the front side or on the back side.

Abstract: It is provided a method for enabling access control for access to a physical space secured by a lock device. The method is performed in a security device and comprises the steps of: obtaining at least one image captured using a first camera of a portable key device, the at least one image being captured in a vicinity of the lock device; receiving a template decryption key from a lock device over a short-range communication link; obtaining a credential associated with the lock device; matching the at least one image with a plurality of templates, each template being associated with a lock device, which comprises obtaining the plurality of templates by decrypting encrypted templates using the template decryption key; and wherein a positive match is a necessary condition for opening the lock device.

Abstract: It is provided a method for selectively granting access to a physical space secured by a barrier. The method is performed in a credential evaluator and comprises the steps of: determining a matching list containing a strict subset of credential identifiers of credentials within range of an antenna provided in a proximity of the barrier, wherein the matching list is based on how long each credential has been within range of the antenna; obtaining a set of biometric templates, consisting of biometric templates respectively associated with the credential identifiers of the matching list; obtaining biometric data of a person being closest to the barrier; and wherein a positive match between biometric data and one of the biometric templates is a necessary condition for granting access to the physical space.

Abstract: It is provided a method for determining when access control of an electronic lock, controlling access to a restricted physical space, should be performed. The method is performed in an intent determiner and comprising the steps of: obtaining movement data from a first sensor of a portable key device, the movement data indicating movement of the portable key device; obtaining a distance indicator from a second sensor, the distance indicator being indicative of distance between the electronic lock and the user; determining when there is user intent to open based on both the movement data and the distance indicator; and triggering access control to be performed only when user intent has been determined.
