发明名称 Method for detecting the abnormal use of a safety processor
摘要 The method involves analyzing usage of a safety processor e.g. chip card, during a preset observation period. Number of solicitation is determined from analysis of an average value by a time unit of the processor during the observation period. A sanction is applied to a terminal whose severity level increases gradually, if the average value is more than a threshold. The average value is determined during an activity period of a safety processor during the observation period. Independent claims are also included for the following: (1) a safety processor intended to control access to obscure digital content provided by an operator to a reception terminal (2) a computer program having instructions of program code for execution of steps of the method.
