A method for providing an authenticated connection between at least two communication partners (12, 14) having the following steps: - Provision of a shared secret key for the at least two communication partners (12, 14); - establishing an anonymous signal-conducting connection between the at least two communication partners (12, 14), wherein all messages of the connection between the at least two communication partners (12, 14) are encrypted with the shared secret key; - authentication of the connection between the at least two communication partners (12, 14) by a user; wherein the authentication of the connection between the at least two communication partners (12, 14) by the user comprises the following steps: - calculation of a first integrity check value on the basis of the shared secret key by the first communication partner of the at least two communication partners (12, 14); - calculation of a second integrity check value on the basis of the shared secret key by the second communication partner of the at least two communication partners (12, 14); - reproduction of the integrity check value calculated by the first communication partner by the first communication partner; - reproduction of the integrity check value calculated by the second communication partner by the second communication partner; - comparison of the integrity check value reproduced by the first communication partner with the integrity check value reproduced by the second communication partner by a user; - confirmation of the equality of the integrity check value reproduced by the first communication partner and of the integrity check value reproduced by the second communication partner by the user; wherein the authentication of the connection between the at least two communication partners (12, 14) is carried out by the user by the confirmation of the equality of the integrity check value reproduced by the first communication partner and of the integrity check value reproduced by the second communication partner; wherein the anonymous signal-conducting connection between the at least two communication partners (12, 14) is based on a transport layer security protocol. - Provision of a shared secret key for the at least two communication partners (12, 14); - establishing an anonymous signal-conducting connection between the at least two communication partners (12, 14), wherein all messages of the connection between the at least two communication partners (12, 14) are encrypted with the shared secret key; - authentication of the connection between the at least two communication partners (12, 14) by a user; - calculation of a first integrity check value on the basis of the shared secret key by the first communication partner of the at least two communication partners (12, 14); - calculation of a second integrity check value on the basis of the shared secret key by the second communication partner of the at least two communication partners (12, 14); - reproduction of the integrity check value calculated by the first communication partner by the first communication partner; - reproduction of the integrity check value calculated by the second communication partner by the second communication partner; - comparison of the integrity check value reproduced by the first communication partner with the integrity check value reproduced by the second communication partner by a user; - confirmation of the equality of the integrity check value reproduced by the first communication partner and of the integrity check value reproduced by the second communication partner by the user;
