A method for initializing encrypted data transmission using a common reference character chain (100) and shared use of a password, which has:Determining a generalized diffie hellmann - - tuple (201);Generating a single simulation reliable, knowledge of free proof, which a consistency of the generalized diffie hellmann - - tuple proves (204); andEncrypt a message according to the generalized diffie hellmann - - tuples (108a),the method is carried out by a processor,the common reference character chain (100) of a cyclic group g of selected elements g, a and k, and wherein the generalized diffie hellmann - - tuples elements s and s in the cyclic group g, wherein the elements s and s ′ can be obtained by a random number x is selected, wherein the element s is determined by the element g with the arbitrary whole number x is greatly increased, and the element s ′ is obtained by the element a with the random whole number x is greatly increased.
