The Creation of Steganographic Effect in the Systems of Electronic Signature

As is known, the method of electronic digital signatures is used to protect the transmitted information from unauthorized changes, in the channels of communication, from the moment of sending the document to reception by the receiver. The task of encryption of the information itself in this method is not worth it. When using this method, in some cases, the task is to hide some of the transmitted information from unauthorized persons who should not guess the existence of such information. The article introduces an algorithm for implementing the "Steganography" effect, when applying the method of electronic digital signatures based on the RSA method. The article describes the corresponding algorithm, gives a practical example of the implementation of this algorithm. A conclusion is drawn. That the application of this algorithm does not require a change in the RSA method, do not introduce new requirements, but allows you to close a portion of the transmitted information to unauthorized persons.
