Method for producing a secure communication channel for a terminal, the method having the following method steps of: - setting up a secure communication channel between a communication partner and a backend by means of a communication protocol, an item of channel binding information respectively being stipulated for the backend and for the communication partner by the communication protocol; - producing a communication channel between the communication partner and the terminal; - transmitting the channel binding information relating to the secure communication channel to the terminal by means of the communication partner; - storing the channel binding information on the terminal; - creating a data structure and a first digital signature across the data structure by means of the backend using a first private key, the digital signature being able to be checked using a first public key; - sending the data structure and the digital signature from the backend to the terminal; and - checking authenticity of the data structure using a checking algorithm for verifying the digital signature using the public key by means of the terminal and/or by means of the communication partner, characterized in that - the data structure comprises the channel binding information and/or basic information from the backend, - the checking algorithm additionally checks the stored channel binding information and the channel binding information in order to determine the authenticity, - the secure communication channel meets security requirements stipulated by the backend, the terminal checking the first signature in order to determine whether the communication channel actually meets the security requirements of the backend. - setting up a secure communication channel between a communication partner and a backend by means of a communication protocol, an item of channel binding information respectively being stipulated for the backend and for the communication partner by the communication protocol; - producing a communication channel between the communication partner and the terminal; - transmitting the channel binding information relating to the secure communication channel to the terminal by means of the communication partner; - storing the channel binding information on the terminal; - creating a data structure and a first digital signature across the data structure by means of the backend using a first private key, the digital signature being able to be checked using a first public key; - sending the data structure and the digital signature from the backend to the terminal; and - checking authenticity of the data structure using a checking algorithm for verifying the digital signature using the public key by means of the terminal and/or by means of the communication partner, characterized in that - the data structure comprises the channel binding information and/or basic information from the backend, - the checking algorithm additionally checks the stored channel binding information and the channel binding information in order to determine the authenticity, - the secure communication channel meets security requirements stipulated by the backend, the terminal checking the first signature in order to determine whether the communication channel actually meets the security requirements of the backend.
