The world it knows today would be impossible
without cryptography. This Paper is presenting study of
cryptography and problem associating with existing encryption
model is also presented. Furthermore this is proposing encryption
model. This encryption model is based on the stream cipher
concept where it will be encrypt and decrypt any type of data file
in bit wise way. The primary goal of this paper is to improve
level of security. The proposed encryption model will analyze by
using a parameter called Avalanche effect. Plaintext and
encryption key are mapped in binary code before encryption
process. Avalanche Effect is calculated by changing one bit in
plaintext keeping the key constant and by changing one bit in
encryption key keeping the key constant. Expected experimental
results shows that the proposed encryption model exhibit
significant high. Avalanche Effect will improve the level of the
security.

The proposed encryption model, presented in this paper is
very simple to understand and it will easy to implement.
The 128 bits key length for any particular file which will
certainly enhance the security features. Expected outcome
section indicates that the proposed encryption model is
definitely comparable with existing encryption model. The
performance of Proposed Encryption model will
significantly better than other encryption model. For large
files, proposed encryption model will be very suitable. The
proposed encryption model will be applicable to ensure
high security in transmission of any file of any size.
