ABSTRACT-
The Data Encryption Standard (DES) is the most common Secret Key Cryptography scheme. DES was designed by IBM in the 1970 and adopted by the National Bureau of Standards (NBS). This paper proposes a new scheme to enhance the security of cryptosystem. DES is widely used throughout the world for information security. DES so far has been stronger than other cryptosystems in the security. But, due to the advancement in the hardware technique, DES may be attacked by parallel processing. Thus a new scheme to strengthen the DES is needed to protect the cryptosystem. This new scheme will use Triple DES Three Times with RSA Algorithm. This will provide 504 bit key length. This results in enhancing the security level along with an increase in File size which is the major drawback in this scheme. In future we are trying that security level is increased but file size remain constant.
Keywords- Cryptography, Cryptanalysis, Data Encryption Standard, DES, RSA, Triple DES, Key Length.
