摘要：Information security is thebest approach deliberated to keep data secure from unauthorized access. Nowadays, people feel more convenience usinga chat applicationon a smartphone to communicate with each other than calling or short messageservices (SMS) features. Major advantages of chat application are there are no limitations of message size, no limitations of the number ofconsumers to use it; especially text as well as any document can be sent easily. In this paper, we implement a secure chatting application using asymmetric cryptography algorithms. The proposed system allows the users to communicate via text messages, voicemessages, and photos. The proposed system usedthe NTRU algorithm to generate the key pair and exchange to produce the shared key that will be used for theencryption of data. For the text message, the voice, andimages we used the NTRU security algorithm for encryption and decryption.In review, when it comes time to analyze the actual performance, we get the same security levels; NTRU has a good performance which is better than ECC and RSA.
