Key device and associated method, computer program and computer program product
First Claim
1. A key device comprising:
- a mechanical interface for mechanically manoeuvring a lock device upon successful access control, the mechanical interface comprising a connector for powering the lock device and for communication with the lock device such that the lock device is able to perform electronic access control using the key device;
a clock;
a memory;
a radio communication module; and
a controller arranged to, using the radio communication module communicate online with an access control device and use the memory as temporary storage for offline communication between the access control device and one or more lock devices;
wherein the controller is arranged to receive an updated time for the clock of the key device by sending a challenge code to the access control device;
receiving a response code along with the updated time, the response code being based on the challenge code; and
determining the updated time to be valid when the response code is determined to be valid.

16. A method, performed in a key device, the key device comprising a mechanical interface for mechanically maneuvering a lock device upon successful access control, the mechanical interface comprising a connector for powering the lock device and for communication with the lock device;
- and a clock, the method comprising the steps of;
communicating online, using a radio communication module of the key device with an access control device;
comprising receiving an updated time for the clock of the key device by;
sending a challenge code to the access control device;
receiving a response code along with the updated time, the response code being based on the challenge code; and
determining the updated time to be valid when the response code is determined to be valid; andusing a memory of the key device as temporary storage for offline communication between the access control device and one or more lock devices. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A computer program comprising computer program code which, when run on a key device comprising a mechanical interface for mechanically maneuvering a lock device upon successful access control, the mechanical interface comprising a connector for powering the lock device and for communication with the lock device;
- and a clock, causes the key device to;
communicate online, using a radio communication module of the key device with an access control device wherein the computer program code causes the key device to receive an updated time for the clock of the key device by sending a challenge code to the access control device;
receiving a response code along with the updated time, the response code being based on the challenge code; and
determining the updated time to be valid when the response code is determined to be valid; anduse a memory of the key device as temporary storage for offline communication between the access control device and one or more lock devices. - View Dependent Claims (27)
