CHAT SIMULATOR USING AES ENCRYPTION

Abstract

Smartphones have become an integral part the lives of individuals and their priorities The present moment. The most visible uses are to chat and chat programs Most of these apps do does not provide the necessary protection and privacy information exchanged between users. Chat apps have become one of the most important and popular smartphone apps. It has the ability to exchange text messages, images and files that can freely communicate with each other. All messages must be protected and in this paper the encryption to used for secure all messages is by using AES encryption. AES (Advanced Encryption Standard) is a symmetric encryption algorithm widely used to keep data confidential in Internet networks. AES uses a block cipher with a block length of 128 bits and can encrypt data with keys consisting of 128, 192, or 256 bits. AES is one of the strongest encryption algorithms available today. It has been adopted by many organizations, including governments, banks, and technology companies. AES security is based on mathematical complexity and is difficult to crack even on ultra-fast computers. The AES encryption process involves multiple steps such as replace, move, and merge. The original data is split into smaller blocks and encrypted with the provided key. The blocks then change periodically, complicating the data patterns an attacker might find
