ABSTRACT
Now-a-days the usage of internet increases tremendously so, there is a need of security for the data. Cryptography
is a process of scrambling the data into unknown format which provides security to the data. Modern
cryptography is mainly based on mathematical theory and computer science practice. Cryptography process is
done with the help of encryption and decryption. The basic two ideas behind the cryptography technique are
substitution and transposition. This paper presents a multistage encryption algorithm. At the end of each stage an
intermediate cipher is produced. The key is generated by using SEEDED SDES algorithm. Final cipher text is
derived from the local binary pattern (LBP).
