Abstract:
The introduction of Short Messaging Services (SMS) has fundamentally altered the
way people communicate and share information. Every day, billions oftext messages
are transferred around the world in plain text format, putting users' privacy and security
at risk. SMS continues to be vulnerable to security vulnerabilities and loopholes,
thanks to a growing lot ofsoftware crackers out there on the internet. For a long time,
information security was assumed to be limited to personal computers and networks.
Malicious attackers are now targeting mobile devices and their users as the technical
trend shifts away from desktops and toward mobile devices. This project's goal is to
create a safe messaging system that enables smartphonesto reduce these vulnerabilities
and loophotes while sending and receiving messages. Our goal is to build an app for
end-to-end message encryption that can hide messages while being transmitted from
source device to destination using the Hybrid Cipher Algorithm. This application is
designed for both Android and IOS based devices. The hybrid technique incorporates a
combination ofvarious cryptographic algorithms that works together to provide secure
message communication. Our program is a peer-to-peer security mechanism that
.......ensures secrecy, security services for verification; integrity; and non-repudiation.'
