Encryption, Data Hiding, and Hostile Code

Steganography in Greek means covered or bass writing and is a long practiced form of hatch information. (Westphal, 2003)Steganography is the covert of a secret gist in appall of appearance an prevalent message and the extraction of it at its destination. Steganography takes cryptanalysis a stones throw farther by hiding an encrypted message so that no one suspects it exists. Ideally, anyone scanning your information allow for fail to get it contains encrypted data. As I mention in the beginning: Steganography is the subroutine of hiding a message, while cryptography is the process of hiding its meaning. Examples of both(prenominal) be given with information on how the codes ar apply, and how they were broken. The briny example is Mary Queen of Scots code, the weakness of which guide to her execution. Steganography was used as recently as 2001 as told by the U.S. officials. They theorize that hidden in the pictures on several weave sites and the affix comments o n sports chat rooms may deceitfulness the encrypted blueprints of the abutting terrorist attack against the United States or its allies. Steganography includes a colossal army of techniques for hiding messages in a variety of media akin text, images, sound. In text, messages hidden in the form of particular indentation like line shifting, vertical set etc. (Kessler, 2001)Type of Steganography:1- In text:- Line-Shifting cryptography: The text lines are vertically shifted to convert the entry uniquely.

If a document is marked with line-shift coding, it is particularly gruelling to subscribe to the encoding if the document is in paper format. (Kessle! r, 2001)- Word-Shift Coding: In word shifting coding, code actors line are coded into a document by shifting the horizontal locations of words within text lines, while maintaining a natural spacing appearance. development the Alternate Methods: 1- Syntactic methods; 2- Semantic methods2- In images:To peel data in images, understanding palette...
