<p>The invention relates to a security-device (10) for enabling a secure data transmission between a first communication device (20) and at least one second communication device (30) over an inherently insecure data connection and / or with an inherently insecure first communication device (20), comprising a receiving means (2) for receiving a second authentication request (105) from the at least one second communication device (30) regarding a data transmission request (101) from the first communication device (20) to the at least one second communication device (30), the receiving-means (2) being coupled with an output means (3) for providing information about the data transmission request (101) to a user, an input means (4) for the inputting of authentication data (110) by the user, a means for generating a third authentication request (106) for the at least one second communication device (30) by the user at the security-device (10) in dependence of the authentication data (110), and a first connection-means (1) configured so that only predefined enable signal (103) is receivable and / or processable by the security-device (10) and that the third authentication request (106) is only transmittable to the at least one second communication device (30), after the correct receipt of the enable signal (103). The invention also relates to a method for a secure data transmission.</p> |
