Abstract:
Nowadays, Internet and network applications are
growing very fast, so critical information is needed to protect .
Crypto algorithms play a main role in information security
systems. In this paper, we present secure data transfer by using
hybrid cryptosystem. It used cryptography for confidentially,
authenticity and integrity of information during transmission.
This system describes describes symmetric, asymmetric and
digital signature. This system implements a secure information
transfer between any two parties so that they can securely
transmit and access critical information. To implement this
system AES, RSA and digital signature with MD-5 algorithms
are used. The implementation is written in C# using Microsoft
Visual Studio 2005.
