Abstract:
Computer techniques are progressing
remarkably and the amount of electronically
transmitted information is increasing every day.
Different security measures can be employed to
ensure the integrity and confidentiality of secret
information. As a result, steganography has
become an interesting and challenging field of
research striving to achieve greater immunity of
hidden data on the host cover media like image,
audio, or text. Although techniques for images or
sounds have mainly been studied, there are few
examples of research of the information hiding
method on text data. The proposed system uses
an SOAP message as cover text, embedded secret
information using stego-key. Steganography
especially combined with cryptography is a
powerful tool which enables people to
communicate without possible eavesdroppers
even knowing there is a form of communication
in the first place. It provides double security.
Digital Signature which is a cryptographic
technique is used to authenticate messages
between parties. In this study, we propose a
secure and undetectable steganography
technique to be used for SOAP signature
messages within XML Web services
environments. This technique is embedded secret
data into an innocuous cover text by shuffling
XML elements to form the stego text with
minimum degradation.
