In which of these attacks will a steganalyst use a random message to generate a stego-object by using some steganography tool, to find the steganography algorithm used to hide the information?
A. Chosen-message attack
The textbook defines a Chosen-message attack as one where the attacker selects a message to be hidden and then uses this information to analyze and deduce the steganography algorithm used. This method helps in understanding how the algorithm works by observing how the chosen message is embedded.
A< Chosen message attack. The steganalyst generates a stego-object from
some Steganography tool or algorithm from a chosen message. The goal
in this attack is to determine corresponding patterns in the stego-object
that may point to the use of specific Steganography tools or algorithms.
(This is the most powerful attack.)
