Abstract:
Today, people use widely computer networks to
communicate from one place to another. When people use
computers, they will need necessary to protect the information
and to thwart the hackers. So, people interconnect their secret
data by using cryptographic algorithms. But the hackers try to
know the key. Therefore, the key secure important in the
cryptographic system. In this paper, AES and RSA algorithms
are joined to use in the encryption and decryption. AES
algorithm is used for file encryption and RSA algorithm is used
for key encryption. Any file is encrypted with RSA algorithm
using the receiver’s public key. This system must construct
within the local area network (peer to peer network). It will be
used for all businesses, governments, militaries and academic
organizations.
