Patent application number | Description | Published |
20090116650 | METHOD AND SYSTEM FOR TRANSFERRING INFORMATION TO A DEVICE - Methods and systems for transferring information to a device include assigning a unique identifier to a device and generating a unique key for the device. The device is located at a first site, and the unique identifier is sent from the device to a second site. The unique key is obtained at the second site, and it is used for encrypting information at the second site. The encrypted information is sent from the second site to the device, where it can then be decrypted. | 05-07-2009 |
20090172392 | METHOD AND SYSTEM FOR TRANSFERRING INFORMATION TO A DEVICE - A system and method for transferring information include generating a public/private key pair for programming equipment and sending the programming equipment public key to a certificate authority. A programming equipment certificate is generated using the programming equipment public key and a private key of the certificate authority. The programming equipment certificate and a certificate authority certificate are sent to the programming equipment. Information is transferred to or from the programming equipment in response to an authentication using the programming equipment certificate and the certificate authority certificate. | 07-02-2009 |
20090172401 | METHOD AND SYSTEM FOR CONTROLLING A DEVICE - A system and method for controlling a device. Data that was encrypted using a first encryption scheme is decrypted, then re-encrypted using a second encryption scheme. The re-encrypted data is then decrypted. | 07-02-2009 |
20090172489 | CIRCUIT ARRANGEMENT AND METHOD FOR CHECKING THE FUNCTION OF A LOGIC CIRCUIT IN A CIRCUIT ARRANGEMENT - A circuit arrangement comprising a logic circuit to be tested and a test circuit is provided. The logic circuit is designed to provide output data from input data, said output data being generated from the input data by logic-circuit-internal combinations, such that the output data are in a predetermined relationship with the input data. The logic circuit is designed to detect whether the relationship is fulfilled and to provide an error signal if the relationship is not fulfilled. The test circuit is designed to alter logic-circuit-internal combinations. The test circuit is designed to detect the error signal, and is furthermore designed to output an alarm signal if the error signal is not detected upon alteration of the logic-circuit-internal combinations. | 07-02-2009 |
20090206165 | CONTACTLESS CHIP MODULE, CONTACTLESS DEVICE, CONTACTLESS SYSTEM, AND METHOD FOR CONTACTLESS COMMUNICATION - A contactless chip module including a power supply, adapted to supply the contactless chip module with power obtained from an electromagnetic field; a first receiver adapted to receive an actively modulated signal; and a second receiver adapted to receive a passively modulated signal contained in the electromagnetic field. | 08-20-2009 |
20090207016 | APPARATUS AND METHOD FOR SECURE SENSING - An apparatus including a sensor configured to sense a physical quantity, an actuator configured to manipulate the physical quantity in a predefined manner, and a detection circuit configured to output an alarm signal in case the sensor does not react to the manipulation of the physical quantity in an expected way. | 08-20-2009 |
20090289761 | SECURE METHOD FOR BIOMETRIC VERIFICATION OF A PERSON - In various embodiments, a method for biometric verification of a person is provided. The method may include detecting a biometric sample of a biometric characteristic of the person, and reading out a stored biometric feature from a data carrier and carrying out a comparison of the stored biometric feature with the detected biometric sample by means of a control unit; wherein at least one data area of the stored biometric feature is altered by means of disturbances, the control unit determines the altered disturbed data area of the stored biometric feature and omits the determined disturbed data areas during the comparison. | 11-26-2009 |
20100013631 | ALARM RECOGNITION - A method and apparatus of recognizing an alarm scenario in a chip card. The method includes detecting a deviation of a property, and determining whether the deviation is a result of an alarm scenario. | 01-21-2010 |
20100031026 | METHOD AND SYSTEM FOR TRANSFERRING INFORMATION TO A DEVICE - A system and method for transferring information to a device include sending a first challenge from an information provider to programming equipment, and responding to the first challenge by the programming equipment. A second challenge is sent from the programming equipment to the information provider, which responds to the second challenge. Information is encrypted by the information provider and sent from the information provider to the programming equipment. | 02-04-2010 |
20100031059 | SECURITY DEVICE, SECURE MEMORY SYSTEM AND METHOD USING A SECURITY DEVICE - A security device including a first external interface; a second external interface; and a security controller connected to said first external interface and said second external interface, said security controller being adapted to validate an access right based on a codeword received via said first interface to perform an encrypted memory access via said second external interface to an external memory coupleable to said second external interface, and to prevent that encrypted memory access via said first external interface or prevent any output of data via said first external interface depending on data received via said second external interface in case of a negative validation. | 02-04-2010 |
20140122881 | METHOD AND SYSTEM FOR CONTROLLING A DEVICE - A system and method for controlling a device. Data that was encrypted using a first encryption scheme is decrypted, then re-encrypted using a second encryption scheme. The re-encrypted data is then decrypted. | 05-01-2014 |
