Method for securely interacting with a security element

摘要

In a method for securely interacting with a security module (200), which is integrated in a terminal (100), via an input device (180) of the terminal (100), the input device (180) is reserved by a security application (180) which can be executed in a trusted area (130) of the terminal (100). First authentication data (PIN 1) are then input via the reserved input device (180). The security application (150) derives second authentication data (PIN 2) from the first authentication data (PIN 1) by means of secret data (144) stored in the trusted area (130). Said second authentication data (PIN 2) are then encrypted by the security application (150) and are transmitted to the security module (200) and/or to a server. The received, encrypted second authentication data (PIN 3) are finally decrypted in the security module (200) and/or the server.
