20120189125 | METHOD FOR ESTABLISHING A SECURE COMMUNICATION CHANNEL - In a method for establishing a secure communication channel between a portable data carrier ( | 07-26-2012 |
20120331302 | METHOD FOR AUTHENTICATING A PORTABLE DATA CARRIER - A method for authenticating a portable data carrier ( | 12-27-2012 |
20130009752 | SYSTEM AND METHOD FOR THE PRESENCE RECOGNITION OF A SECOND PORTABLE DATA CARRIER BY A FIRST PORTABLE DATA CARRIER - A system for recognizing the presence of a second portable data carrier by a first portable data carrier, wherein the data carriers have respectively a contactless interface with an antenna and an electronic circuit for storing and/or processing data. An RFID reading device supplies the data carriers with energy and for the respective communication of the data carriers with the reading device. In the first and the second data carrier there is respectively provided a further communication device, via which an additional, direct communication channel, independent of the field of the reading device, is made available between the first and the second data carrier, to thereby check the immediate presence of the second data carrier in the field of the reading device by the first data carrier. | 01-10-2013 |
20130031357 | METHOD FOR SECURE TRANSFER OF AN APPLICATION FROM A SERVER INTO A READING DEVICE UNIT - A method and a system for secure transfer of an application from a server (S) into a reading device unit ( | 01-31-2013 |
20130151854 | METHOD FOR AUTHENTICATING A PORTABLE DATA CARRIER - A method for authenticating a portable data carrier ( | 06-13-2013 |
20130326235 | CRYPTOGRAPHIC METHOD - In a cryptographic method between a portable data carrier and a terminal device there are employed a public data-carrier key and a secret data-carrier key of the data carrier as well as a public terminal key and a secret terminal key of the terminal device. The data carrier employs as a public data-carrier key a static public key. As a secret data-carrier key the data carrier employs a secret key that is derived from a secret basic key associated with the public data-carrier key. Within the framework of the method, the terminal device checks an authentication parameter associated with the data carrier and different from the data-carrier keys. | 12-05-2013 |
