Abstract :
Cryptographic techniques offers authenticity, Integrity and secrecy during data transmission. In this paper, a hybrid cryptosystem, which uses both symmetric crypto algorithm and hashing techniques, is proposed. The hash value of message is calculated using MD5 algorithm. The same message is encrypted using double DES algorithm using secret keys. The ciphertext produced from double DES and hash value are combined and transmitted. At the receiver side, the ciphertext is separated from hash value and decrypted to get original message. The hash value of decrypted message is calculated at receiver side also using MD5 algorithm. This hash value is compared with hash value received from sender to check data integrity.
