Definitions

  • the present invention generally relates to an access control system and a method for using said system.
  • the present invention relates to locking system and a corresponding method for controlling and customizing access of a mobile key to a lock.
  • the invention provides an easy, convenient and still safe system and method which allows an administrator to control and customize a mobile phone which comprises an NFC (Near Field Communication) device, as a mobile key for one a plurality of locks of a locking system.
  • NFC Near Field Communication
  • the method and system according to the present invention is not limited on access control systems for locks but can be used for any kind of access control systems.
  • Locking systems with a plurality of electronic locks and a plurality of electronic keys are known in the art.
  • transponders (active or passive) or RFID cards can be used as portable electronic keys (in the following also called credentials), which provide a plurality of advantages over pure mechanical locking systems with mechanical keys and mechanical locks.
  • the electronic keys and/or the electronic locks may be programmed individually, which allows to provide very flexible locking plans. For instance, each hotel guest or employee has its own electronic key, which can be individually programmed for unlocking a particular lock or a plurality of locks during a specific period of time.
  • the electronic key e.g., the RFID card
  • a card reader/writer of an administrator is required.
  • a locking system management e.g. a central computer with appropriate software which allows the administrator to program the electronic key(s) and/or the individual lock(s) individually.
  • a drawback of such known locking systems is, however, that the electronic key has to be connected physically to the card reader of the administrator for programming or re-programming.
  • the electronic locks have to be connected to the locking system management to allow individual programming of the locks.
  • Such an connection between the locking system management and the electronic locks typically requires complex wiring or sophisticated wireless networks.
  • the present invention further relates to a corresponding method for administrating the locking system according to the present invention.
  • a locking system comprises at least one electronic lock, preferably a plurality of electronic locks and at least one portable electronic key, preferably a plurality of electronic keys.
  • the system further comprises a locking system management (also called Locking-System-Management; LSM in the following) which allows controlling and administrating access of individual or groups of electronic keys to individual or groups of electronic locks.
  • LSM Locking-System-Management
  • a locking system according to the present invention a may be based on a digital locking and access control system (see e.g. System 3060 from SimonsVoss) which is an electronic version of a mechanical locking system which provides all the functions of a classical access control system.
  • Electronic transponders electronic keys
  • Electronic keys may be used instead of mechanical keys, along with electronic locks, such as digital locking cylinders. Radio communication between the electronic locks and the electronic keys takes the place of a key turning in a lock.
  • Data is preferably transferred from the transponder to the locking cylinders or SmartRelays inductively at a frequency range of 25 kHz. The typical reading distance up to 40 cm for the locking cylinder and up to 120 cm for the SmartRelays may be provided.
  • the locking system according to the present invention is preferably a further advancement of the above discussed locking system.
  • the present invention provides the further advantage that access management of electronic locks, which are not connected via a network to the LSM, can still be flexibly and individually managed by using mobile phones (also labeled cell phones throughout the present application) as electronic keys, wherein said mobile phones are connectable to the LSM via the cellular network (mobile network; mobile communication network) of the mobile network operators (mobile phone providers).
  • mobile phones with NFC (Near Field Communication) devices are used as mobile electronic keys.
  • Transponders in particular passive transponders, are well known in the art to be used in electronic access control devices.
  • RFID Radio Frequency IDentification
  • An RFID tag is typically a small object that can be attached to or incorporated into a product.
  • RFID tags contain silicon chips to enable them to receive and respond to queries from an RFID reader/writer.
  • the power supply to the transponder and the data exchange between the transponder and a reader is achieved without the use of galvanic contacts, using instead magnetic or electromagnetic fields.
  • An RFID system is always made up of two components, the transponder/RFID tag and the reader.
  • NFC Near Field Communication
  • NFC communication is enabled by bringing two NFC-compatible devices within a few centimeters of one another. This "context of proximity" is basis for many new NFC-based applications, e.g.: contactless transactions such as payment, transit ticketing, simple and fast data transfers including electronic business cards and access to online digital content or access control to locking systems.
  • NFC is a standards-based technology that enables simple and safe two-way interactions between electronic devices, allowing consumers to perform contactless transactions, access digital content, and connect electronic devices with a single touch.
  • NFC is not an RFID system, but a wireless data interface between devices, similar to infrared or Bluetooth.
  • Bluetooth wireless technology was designed to replace cables between cell phones, laptops, and other computing and communication devices within a 10-meter range.
  • NFC provides several features with are of interest in relation to RFID systems. For instance, data transmission between two NFC interfaces uses high-frequency magnetic alternating fields in the frequency range of 13.56 MHz.
  • NFC is compatible with existing RFID standards and makes it possible both to read transponders and to emulate transponders, i.e., to behave like transponders.
  • an NFC interface has a 13.56 MHz transmitter and a 13.56 MHz receiver that are alternately connected to an antenna.
  • NFC devices are active devices and are unique in that they can change their mode of operation to be in (i) reader/writer mode, (ii) peer-to-peer mode, or (iii) card emulation mode.
  • the different operating modes are based on the ISO/IEC 18092 NFC IP-1 and ISO/IEC 14443 contactless smart card standards.
  • an NFC tag is typically a passive device (for example, integrated in a smart poster) that stores data that can be read by an NFC-enabled device.
  • NFC card and “NFC tag” will be used synonymously.
  • a "NFC card” and “NFC tag” are technically the same, however, contactless cards used in ticketing and payment often include additional technology to store secure data.
  • the NFC device In reader/writer mode, the NFC device is capable of reading NFC tag types, such as in the scenario of reading an NFC Smart Poster tag.
  • P2P Peer-to-Peer
  • two NFC devices can exchange data. For example, a user can share Bluetooth or WiFi link set up parameters or a user can exchange data such as virtual business cards or digital photos.
  • the NFC device appears to an external reader much the same as a traditional contactless smart card (RFID card).
  • RFID card contactless smart card
  • This mode is secure and supported by a contactless communication API.
  • a secure element on the device communicates and transacts with an external reader over RFID hardware.
  • the internal security element interacts with an external reader.
  • the application is notified when the external reader has been detected, and, if needed, the application communicates with the secure element, using the contactless communication API connection interface.

  • the LSM and the mobile phone negotiate at least one secret key, e.g., a secret key for symmetric encryption and/or at least a pair of keys for asymmetric encryption.
  • Such an initial negotiation is preferably done in a secure environment, e.g., by connecting the mobile phone and/or the NFC device to the LSM via cable or a local read/write device.
  • a universal mobile key application may be used for all mobile phones. However, it may be necessary to adapt this mobile key application to the operating system of the mobile phone.
  • the individuality of the electronic key is preferably based on the individual key data set, not on the basis of the basis application. Accordingly, the mobile key application may be distributed via classical data storage medium or may be provided on a server which allows a user to download the application.

  • a mobile phone 1 may be individually programmed for unlocking particular electronic locks for a limited time, thus making sure that employees will have to upload their changing access authorizations on a regular basis. For instance, by means of the key distribution service 200, a mobile phone may be programmed every Monday via the cellular network, to get access to specified locks at location 102. In case the employee should not get access to location 102, programming via the cellular mobile network is abandoned.

  • the locking system management preferably comprises at least one computer which allows individual management of all electronic keys, preferably including active transponder, passive transponder and/or mobile phones used as electronic keys according to the present invention.
  • the locking system management preferably also allows that some or all of the locks which form part of the locking system may be programmed individually. For instance, some of the locks may be connected to the LSM via a network. Some of the locks may not be connected to the LSM via a network. Programming such locks, however, may be achieved by means of a portable computer (laptop, handheld, smartphone, etc.), e.g., by programming the locks locally using the portable computer.
  • mobile phones are preferably not re-programmed via a local reader/writer, but preferably via the cellular mobile network.
  • a user downloads appropriate software on the mobile phone 1.
  • this particular software which enables a mobile phone to work within the locking system according to the present invention, may be transferred locally from the LSM or an other computer authorized by the LSM.
  • This software also called “App”, “app” (acronym for "Application") or "mobile key application” may be provided by an “app store”.
  • the app store according to the present invention is a digital application distribution platform, particularly for mobile phones.
  • the app store allows users to browse and download applications that were developed for the mobile phone.
  • the application (app) can be downloaded directly to a target device (the mobile phone), or downloaded onto a computer and afterwards transferred to the mobile phone.
  • a user may download the mobile key application (app) from an app store as illustrated in step 01 of Fig. 3 .
  • the mobile phone as used as electronic key comprises an NFC device, e.g., an NFC chip.
  • the NFC device preferably further comprises a secure element.
  • the secure element may be embedded within the mobile phone in a secure chip, in the SIM card and/or in an external device, attached to the mobile phone.
  • the key data set which represents or comprises data needed for unlocking a particular lock, is preferably stored within said secure element.
  • the key data set is generated individually for each mobile phone 1. Accordingly, it is preferred that each mobile phone stores a unique key data set in the secure element. Since the secure element of an NFC device is adapted to store sensible data securely, a save mobile key is provided.
  • said key data set is preferably transferred from the Locking System Management 201 via an OTA (Over The Air) key server 202, to the mobile phone 1 as follows.
  • the key data set with the individual access codes is generated at the LSM 201. Since the LSM 201 may bee seen as the "heart" of the system, remote access to the LSM from outside should be avoided.
  • the key data set is encrypted (cryptographically secured) at the LSM by means of a secure key.
  • the encrypted key data set is pushed from the LSM 201 to the OTA key server 202 (see step/arrow 02 in Fig. 3 ).
  • the LSM 201 and the OTA key server 201 are connected via TCP/IP, further preferred via the Internet.
  • the key data set is pushed only in the direction from the LSM to the OTA. In other words, it is preferably not possible to download the key data set from the LSM. Still in other words, pushing the key data set represents a one way direction of sensible data which ensures that manipulation of the LSM from outside is impossible.
  • the LSM 201 may be designed such that the administrator actively controls, e.g., by pressing a button, when a new key data set is pushed to the OTA key server.
  • the LSM 201 may additionally or alternatively designed that any amendment of access control relating to a corresponding mobile phone may result in an automatic push of the corresponding amended key data set to the OTA key server. Further preferred, amended key data set(s) may be regularly or according to an underlying timing plan pushed to the OTA key server. It is, however, preferred that only encrypted key data sets are pushed and subsequently stored on the OTA key server.
  • the OTA key server 201 is preferably provided as a trusted service manager (TSM). Such trusted service managers are typically very save. However, remote access to such OTA server can not be totally avoided such that attacker may hack in worst case the OTA key server and download the stored key data sets. However, since only encrypted key data sets are stored, even hacking the OTA server does not provide a safety problem for the locking system according to the present invention.
  • TSM trusted service manager
  • the user may then download the encrypted key data set from the OTA key server 201 by means of the mobile key application (the app) already installed on his/her mobile phone 1 (see step 03 in Fig. 3 ).
  • the mobile phone network may be used for controlling/managing mobile phones as electronic keys.
  • This provides further advantages over the traditional locking systems which typically suggest connecting the locks via a network for controlling/managing the locks of the locking system with the LSM.
  • the system of the present invention provides further flexibility, especially for locks with are not (logically) connected to the LSM. For instance, a lock may be provided as "hermit lock" anywhere. Access to said lock may still be individually and flexibly managed due to the connection of the LSM to the mobile phone 1 via the cellular network.
  • the mobile key application on the mobile phone 1 is adapted to decrypt (decipher) the encrypted key data set on the mobile phone in a secure manner.
  • the LSM 201 and the mobile key application on the mobile phone 1 both know the preferably individual secure key for encrypting and/or decrypting the key data set.
  • the mobile phone may be physically coupled to the LSM to generate an encrypting and/or decrypting key which is only known by the LSM and the mobile key application on the mobile phone.
  • the encryption/decryption on the LSM/mobile phone may be based on a symmetric key or on the basis of asymmetric keys.
  • This design ensures that solely the mobile key application knowing the secure key may decrypt the encrypted key which is distributed via the OTA key server. After decrypting the key data set, the key data set (the encrypted key data set) is stored in the secure element of the NFC device. Thus, since the secure element of the NFC device is safe against manipulation from outside, security of the locking system according to the present invention is guaranteed.
  • a user may then use the NFC device with the stored key data set for unlocking the door 2 (see step/arrow 04 in Fig. 3 ).
  • the NFC device switches into card emulation mode such that NFC device behaves like a typical RFID device.
  • the NFC device behaves like a well known MIFARE® card which transmits data for unlocking the electronic lock 2 on the basis of the key data set stored in the secure element on the mobile phone 1. This provides the advantage that legacy installed locks, which are unlocked by means of MIFARE cards, may be unlocked by traditional RFIC cards or by means of mobile phones 1 which are customized according to the present invention.
