| Abstract [eng] |
Steganography in networks allows sensitive information to be sent using a variety of header fields that are not used by protocols. Such steganographic methods have been used for a long time now. The main disadvantages of this type of steganography are the integrity of the transmitted confidential information and its small amount. In this work, various steganography methods of TCP/IP stack protocols were analyzed. The main goal is to develop a new or improve the existing steganography method in the RTP protocol. The goal was achieved by improving the method of changing the last voice data bit. A Reed-Solomon error detection and correction code was used. This method can recover the original message in the event of packet loss. It was also investigated whether the bits of the sent message could be hidden not only in the last bit of voice data, but in any of the last four bits of voice data or even using the last two bits of voice data. |
