A Novel Approach of Secure Communication: Encryption Based Compression Technique

Abstract

Transmission of information through a problematic channel for communication assumes an
essential job in the present period subsequently communication security over an overall
system turning into a most rising point. Different advances have been acquainted with satisfy
this need Cryptography and Steganography are two strategies in this period. Cryptography
method distorts the information so that separated from proposed client nobody can get to it.
Be that as it may, it is having an impediment that in this system message exist in encoded
however noticeable shape. So malicious user keeps trying to decrypt that message and once it
is decrypted it reveals its identity. Hence Steganography has been introduced to overcome the
limitation of Cryptography. For secure communication various compression techniques are
available which are described below.
