Abstract:
Mobile phones have changed our day to
day life totally. Short Message Service (SMS) is a
text messaging service component of phone, web,
or mobile communication systems, using
standardized communication protocols that allow
the exchange of short text messages between
devices. On the other hand of the popularity of
SMS, secure messaging transmission is required.
The purpose of secure messaging is to enable
sender and receiver to electronically communicate
both privately and securely. In this proposed
system, Advanced Encryption Standard Algorithm
(AES) is applied to encrypt and decrypt messages
on Android OS. The sender and receiver use the
same key to encrypt and decrypt the messages as
per user requirement in order to improve security
and to get high confidentiality. This application
can run on any device which works on Android
platform and provides a secure encryption of the
data.
