The hardest process of the three steganalysis category

The practice of concealing messages within other data, such as text or images.

The operation finds the remainder of a division

An encryption method where the sender and receiver share a SINGLE private key to use in the encryption

The most important part of the process of the three steganalysis category

When the letter in an alphabet is replaced with a different character or symbol.

This means "hidden or covered"

The last bit in a byte.

The encrypted message generated by a cipher

A computational process that converts data of varying size to a fixed-size

This replaces redundant or insignificant data with covert data

An algorithm used for encryption or decryption?

Uses the covert text itself to generate an overt message. Spam text is a good example

Keys are combined mathematically to create one key used in the encryption/decryption algorithm

This means "to Write"

The original message that needs to be encrypted

A standard that computers use to represent letters , numbers, and symbols

Algorithm behind paired key encryption algorithms that relies on math functions that are easy to do, but hard to undo.

A digital cash system

Rivest, Shamir, and Adelman, the founders of an American computer and network security company.

Encryption method that uses two keys, Public and Private

A file that contains other data and acts like a drive

The science and art of delivering a message securely and confidentially.

A string of characters used as a parameter that determines the output of an encryption algorithm

The easiest process of the three steganalysis category
