MULTI-STAGE ENCRYPTION USING SEEDED SDES

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).
