摘要： It is provided a method for providing a privacy-enhanced delegated access right to unlock a physical lock. The method comprises: obtaining a derivation scalar; receiving a cryptographically signed delegation from the delegator device, the delegation being a data object comprising a public key of the delegator device, a public key of the physical lock, and a derived public key for the delegatee device, and wherein the delegation is cryptographically signed using a secret key that is paired with the public key of the delegator device; obtaining a source secret key for the delegatee device, the source secret key being paired with the source public key; calculating a derived secret key for the delegatee device using the source secret key for the delegatee device and the derivation scalar; providing the delegation to the physical lock; and authenticating the delegatee device with the physical lock using the derived secret key.

摘要： A method for maintaining a log of events in a shared computing environment is provided. One example of the disclosed method includes receiving one or more data streams from the shared computing environment that include transactions conducted in the shared computing environment by a first entity and a second entity that is different from the first entity. The method further includes creating a first blockchain entry for a first transaction conducted in the shared computing environment for the first entity, creating a second blockchain entry for a second transaction conducted in the shared computing environment for the second entity, where the second blockchain entry includes a signature that points to the first blockchain entry, and then causing the first and second blockchain entries to be written to a common blockchain data structure in a database that is made accessible to both the first entity and the second entity.

摘要： According to a first aspect, it is provided a method for requesting access to a physical space secured by a lock. The method is performed in a mobile device of a user and comprises the steps of: authenticating the mobile device with an authentication server, resulting in a token, being a data item, indicating one or more access groups to which the user belongs, wherein the token is cryptographically signed by the authentication server; storing the token in the mobile device; obtain a lock identifier of the lock; and transmitting an access request to an access control device, the access request comprising the token and the lock identifier.

摘要： Systems and techniques for a physical access control systems with localization-based intent detection are described herein. In an example, an access control system may regulate access to an asset. The access control system is adapted to receive a credential for the asset from a key device associated with a user using a first wireless connection. The access control system may be further adapted to store the credential in a cache of memory. The access control system may be further adapted to establish a second wireless connection with the key device. The access control system may be further adapted to request a validation of the credential from an authorization service in response to establishing the second wireless connection with the key device. The access control system may receive a validation token from the authorization service. The access control system may be further adapted to store the validation token in the cache.

摘要： A reader device of an access control system comprises physical layer circuitry and processing circuitry. The processing circuitry is operatively coupled to the physical layer circuitry and is configured to initiate transmission of a command to a credential device; determine a time duration from sending the command to the credential device to receiving a response to the command from the credential device; and generate an indication when the time duration exceeds a relay attack detection threshold time duration.

摘要： The present invention provides a method for recovering a device (D). The method comprises the steps of acquiring a recovery code with the device (D) to be recovered, matching an inherence factor of a user recovering the device (D) with an inherence factor of a user which is assigned to the device, and allowing a recovery of the device (D) if the inherence factor of the user recovering the device and the inherence factor of the user which is assigned to the device sufficiently matches. A further method is provided which comprises the steps of connecting the device (D) to be recovered to a cloud storage in which a backup of the device is stored, requesting a knowledge factor from the user recovering the device (D), allowing a recovery of the device (D) if the possession factor is correctly inputted into the device (D) to be recovered. Further an App is provided which can be stored on a device, which App contains instructions for carrying out the method.
Still further a System is provided comprising a device (D) and an App stored on the device (D) which is adapted to carry out the method.

摘要： 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.
