| Abstract: | This paper analyzes the structure and transmission of IP packets in network communication,and points out the possibility of hidden information in the IP Time To Live Field.Based on this feature,it presents a new steganography scheme that maps the secret messages into IP Time To Live Field and replaces those of IP packets.It proves the feasibility,and the analysis of performance shows the security of the scheme. |
