Implementation of Secure Data Transfer Using Hybrid Cryptosystem

Abstract

Nowadays, Internet and network applications are growing very fast. Thus, people need to protect the information and to thwart the hackers. People interconnect their secret data by using cryptographic algorithms. But, the hackers can try to get the key, and therefore, the key security is the most important role in the cryptographic system. This paper intends to transfer data with high security by using hybrid cryptosystem. Hybrid Cryptosystem uses the secrete-key cryptography to encrypt the data and use the public-key cryptography to encrypt the secrete-key. It uses combination of the AES (Advance Encryption Standard) and RSA (River-Shamir-Adleman ) algorithm. The system is based on the peer-to-peer architecture. In this system, the design of the cryptography technique is based on the digital envelope. The system can support user Authentication portion and data integrity.
