Abstract: A method for establishing a secure connection from a service technician to a component of an automation environment that can be remotely diagnosed and/or maintained and is experiencing failure. A service certificate is required for establishing the secure connection, wherein a secure initial connection is first established to the automation environment by the service technician using a one-time password. With the initial connection, a service certificate required for establishing the secure connection to the component of the automation environment experiencing the failure is subsequently transmitted from the automation environment to the service technician. The secure connection from the service technician to the component experiencing the failure is then established by means of the service certificate. The invention further relates to an automation environment that is suitable for carrying out a method of said kind.

Abstract: In a method and a system (1) for providing target information of an event message for an event occurring at a tag reader (2), the target information is extracted from a signed digital certificate of a tag (4). The event is triggered at a tag reader (2) and can be evaluated by a target computer (6), for example a server. The method and system enhance reconfiguration flexibility and also increase security against manipulation.

Abstract: The present embodiments disclose methods and devices for digitizing documents. The device includes a document-scanning device designed to digitize at least one document existing as a hard copy, and having a security device that is designed to protect the at least one digitize document against unauthorized access on the basis of an identifier that is only valid once.

Abstract: The invention relates to a method for authenticating a user by an application by means of a challenge-response method. In this case, the challenge (5) is displayed in the form of a barcode on a display (6) and is transmitted to a communication device (3) associated with the user. The determined response (8) is input by the user at a user interface (10) of the application.

Abstract: In a system (1) for transmitting RFID identifiers, which can be read from RFID tags (4), to an authentication server (6), at least one RFID protocol message, which is encoded in authentication messages, can be transmitted from an RFID reading unit (2A) to the authentication server (6).

Abstract: In a method for the access control to an automation unit (01), access rights predetermined by the access control are dependant on the operating state of the automation unit (01), wherein at least during an emergency, expanded access rights in relation to normal operation are granted independently of the access rights during normal operation.

Abstract: The invention relates to a method for exchanging data between a mobile telephone and a fixed line telephone. According to the invention, a mobile telephone equipped with Near Field Communication (NFC) technology and a fixed line telephone that is also equipped with NFC technology are initially placed in a reception range, subsequently the mobile telephone and the fixed line telephone are coupled by means of the NFC technology, and then data is transmitted between the mobile telephone and the fixed line telephone by means of the NFC technology. Said coupling occurs when the mobile telephone and the fixed line telephone are authenticated, and two different NFC technologies are used for the authentication of the mobile telephone and the fixed line telephone, and the subsequent transmission of data.

Abstract: In a method for protecting at least parts of product data, which are stored on at least one server and/or in at least one database and associated with a product identified by an RFID tag, from unauthorized access, an authentication and authorization check of an accessing party is performed upon access to a server and/or database, additionally proof being required upon access that the product is located within the discretionary area of the accessing party, the proof being provided by the RFID tag upon detection by an RFID reader by an access token in the form of a data structure, by which the RFID tag authorizes the accessing party to access at least parts of the product data associated with the product identified by the RFID tag, and stored on the server and/or in the database, wherein the product data can be queried and/or changed depending on the application.

Abstract: A digital certificate is configured to confirm the association of a public key assigned to a device as the owner of the public key to the device. The digital certificate further has an additional digital certificate, the additional digital certificate being a certificate of an additional device configured to digitally sign the digital certificate of the device. The certification process can be improved, wherein particularly the verification of digital certificates is improved. The various embodiments are particularly useful for applications where a secure communication of information or data is desired and/or should be made possible.
