摘要
本文通过对IP包的封装结构和通信过程的分析,指出IP包的TTL值隐藏信息的可能性,并提出了基于IP包生存时间的信息隐藏方法。理论分析和实践表明,该方法具有实际应用的可行性和较好的安全性。
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.
