Abstract:
The messaging system has become the
most popular for electronic communication in the
world. This paper is intended to implement secure
messaging system for electronic communication.
In this age of viruses and hackers of electronic
eavesdropping and electronic fraud, security is
paramount. A cryptographic system (or a cipher
system) is a method of hiding data so that only
certain people can view it. A cryptographic system
typically consists of algorithms, keys, and key
management facilities. There are several
algorithms to choose from that vary in the security
they provide, their size, the time it takes to encrypt
or decrypt a block of data. In this system, message
transmission security is controlled by tiny
encryption algorithm (TEA).Tiny Encryption
Algorithm is short program will run on most
machines and encipher safely
