Abstract: Systems and methods may be used for providing wireless power from a mobile device to a digital lock. The mobile device may include a proximity communication antenna to receive an authentication request from the digital lock. The proximity communication antenna may facilitate the mobile device providing wireless power to the digital lock via a wireless power protocol. The proximity communication antenna may send an authorization to the digital lock to cause the digital lock to open.

Abstract: It is provided a method for performing an action by an electronic device (2), based on a first partial secret key (10a) and a corresponding second partial secret key (10b), wherein the first partial secret key (10a) and the second partial secret key (10b) form part of a threshold cryptography scheme (11) associated with a public key (12). The method comprises: transmitting (40), upon the device initialising, a request for a first partial secret key (10a) to a key server (3); receiving (42) the first partial secret key (10a) from the key server (3); storing (44) the first partial secret key (10a) only in volatile memory (70); retrieving (46) a second partial secret key (10b) from non-volatile memory (71); and performing (48) an action based on applying both the first partial secret key (10a) and the second partial secret key (10b).

Abstract: Systems and methods may be used for controlling physical access using a cloud transaction. A method may include receiving an authentication attempt for a user from a mobile device, and authenticating the user for access to a physical space based on the authentication attempt. The method may include receiving identification information corresponding to the user from an access control device, and sending authorization to the access control device to permit the user to access the physical space based on the authenticating the user.

Abstract: It is provided a method for providing hardware integrity control of an electronic device (2). The method comprising: triggering (40) each one of a plurality of components (4a-d) of the electronic device to generate of respective partial secret keys (10a-d) forming part of a threshold cryptography scheme (11) associated with a public key (12), wherein a threshold number of the plurality of partial secret keys (10a-d) are required to be applied in the threshold cryptography scheme (11) for verification against the public key (12); and providing (42) the public key (12) to a hardware verification device (3). A corresponding hardware integrity device (1), computer program (67, 91) and computer program product (64, 90) are also provided.

Abstract: A verifier device of an authentication system comprises physical layer circuitry and processing circuitry coupled to the physical layer circuitry. The processing circuitry is configured to encode an authentication command for sending to a credential device; decode a response communication received from the credential device, wherein the response communication includes a first random number; encrypt the first random number, a second random number, and verifier keying material for sending to the credential device; decrypt encrypted information received from the credential device, wherein the encrypted information includes the first random number, the second random number, and receiver keying material; and calculate a session encryption key using the verifier keying material and the receiver keying material.
