    摘要: For detecting a blocker RFID tag, the following steps are conducted. First, a random identifier of a given bit length is created. Alternatively, an identifier is selected out of a probing set, which is stored on a data storage device. The probing set comprises of identifiers, which are not being used as identifiers for a given set of RFID tags. In a second step, a response from all RFID tags is requested having an identifier matching the random identifier or, respectively, the selected identifier. In a third step, it is determined, depending on receiving or not receiving a response, whether the blocker RFID tag is present.

    摘要: For detecting an invalid RFID tag, an identifier and authentication information is read from a given RFID tag. The authentication information is then verified dependent on at least a given part (IDP_TAG) of the identifier (ID_TAG) and it is determined that the given RFID tag is the invalid RFID tag if the verification was negative. Accordingly, an RFID tag is manufactured by determining an identifier (ID), determining an authentication information dependent on at least a given part (IDP) of the identifier (ID) and storing the identifier (ID) and the authentication information on or in the RFID tag.

    摘要: A method of establishing a trustworthiness level of a participant in a communication connection between a first communication partner and a second communication partner is proposed whereby the communication behavior is adapted to the established trustworthiness level. The participant is equipped with a trustworthiness certificate and a therefrom separated securely stored participant private key. The first communication partner receives the trustworthiness certificate from the participant wherefrom the trustworthiness level is derived and established. The first communication partner tests whether the trustworthiness certificate belongs to the participant by using the participant private key. In case the trustworthiness certificate is confirmed by the test to belong to the participant, the first communication partner communicates the established trustworthiness level to the second communication partner. Then, at least one parameter of the communication behavior is chosen in dependence of the established trustworthiness level.

    摘要: A method of transmitting information data from a sender to a receiver via a transcoder is proposed. The information data comprises confidential information data which is encrypted and non-confidential information data. Security information and transcoding-type information is sent together with the partly encrypted information data to the transcoder which uses the security information and transcoding-type information during a transcoding step. The encrypted confidential information data is thereby transcoded without using its content while the non-confidential information data is transcoded, having access to its content.
