This research will show a sturdy method to hide a text file into an
image using least significant bit algorithm and encrypting this text,
which allows to store English and Arabic texts with various sizes
and ensure that the text file is delivered correctly and secretly.
We take an IDEA Algorithm and add to it some stages depend on
BBM to get an Enhanced Algorithm, which had 3keys, 128-bit
input block.
This paper presents a new type of encryption, using a matrix
asymmetric and symmetric matrix inverse matrix clear text, which
is an internal encryption.
As well as asymmetric encryption, where the ciphertext is inversely
symmetric matrix.
Decryp
tion matrix related to any asymmetric encryption keys
depends on public and private, and is applied to the coded messages
used in the current system ASCII our computers.
