A Hybrid Cryptosystem approach for file security by using merging mechanism

The expeditious growth of internet and networks applications has given rise to many data security issues. Encryption algorithm plays a crucial role in information and network security systems. One of the efficient directions of achieving security data communication is File Splitting mechanism and Hybrid Cryptosystem. This paper presents the hybrid encryption scheme which combines the quick encryption scheme of symmetric algorithm (Blowfish) with the security of asymmetric cipher algorithm (SRNN). The proposed approach includes file splitting and merging mechanism along with hybrid encryption where each slice is encrypted by its corresponding key.
