Abstract:
Security requirement is extremely needed to prevent various
types of network attacks in some environment such as banking, exam question
distribution, and military information exchange process. Files and data are
transferred through networks in such environments. These networks are more
vulnerable to network attacks. This paper presents a system to support secure
network file transfer. The proposed system uses hybrid cryptosystem; Asymmetric
RSA and Symmetric PBE (Password- Based Encryption). PBE uses password to
generate encryption and decryption key. AES algorithm is used for the file
encryption and RSA algorithm is used for key encryption . This system is more
secure than generating keys from storage media. The entire system is implemented
by Java Programming Language.
