| 摘要 |
The invention relates to a method for authenticating and/or identifying a device, a service, a person and/or money in a communication network, consisting of a first communication device and an additional communication device, for example a central database, between which an authentication query is carried out. Initially, a first key is provided in the communication device, which comprises at least one character sequence consisting of individual or several locally modifiable characters which can be dynamically modified in accordance with a measurable variable or an algorithm which is dependent on the measurable variable, rules and/or instructions in the communication device, between two authentication time points. A second key is also provided in the central database or an additional communication subscriber which comprises a character sequence consisting of centrally modifiable characters and optionally non-modifiable characters. In a further step, a transmission and a comparison of the key stored in the central database and the communication device is carried out. |

1. A method for authentication and/or identification of a device, a service, a person and/or financial resources in a communication network comprising a communication device and a central database, between which an authentication query is performed, comprising of the steps:
Providing a first key in the communication device that includes at least a string, comprising
single or multiple locally changeable characters that change dynamically depending on a measured variable or an algorithm depending on the measured variable, rule and/or instructions in the communication device between two authentication time-pointssingle or multiple locally unchangeable characters in this or in a further locally stored string that remain static between two authentication time-points in the communication device, Providing a second key in the central database that includes a string, consisting of
single or multiple centrally changeable characters in this or in a further string that match the locally unchangeable characters or strings of the communication device of the last authentication time point,single or multiple centrally unchangeable characters that correspond to the locally changeable characters or string of the communication device of the last authentication time-point, Transfer and comparison of the key stored in the central database and the communication device,wherein a positive authentication and/or identification of the device, the service, the person and/or the financial resources then takes place at the time of authentication, when at least the following criteria are met:
i. at least partially conformity of the locally unchangeable characters or string in the key of the communication device with the corresponding centrally changeable characters or string in the key to the central database, ii. at least partially mismatch of the locally changeable character or string in the key of the communication device with the corresponding centrally unchangeable characters or string in the last key of the central database,wherein the locally changeable characters or string between two authentication time-points can be changed only in the communication device, but not in the central database and the centrally changeable characters or string can be changed only in the central database, but not in the communication device. |
