SMS Encryption using NTRU Algorithms on Android Application

U 33T , 33T P U 33T ABSTRACT- In these days, security is necessary for all the applications on the network. Number of techniques and algorithms are used for the purpose of providing the security in many fields by many approaches. NTRUis a fast encryption algorithm and it is implemented in various fields but it was yet not implemented on SMS applications on android application. For providing the security to the data transferred on the network, NTRUalgorithm is seen as fast and best algorithm. NTRUis patented and an open source public-key cryptosystem in which lattice-based cryptographysystem is used for encryption and decryption of files. Many applications make use of extensive databases (chats) to store the data and are accessible from anywhere by the multiple people simultaneously via mobile networks or towers. This paper represents the implementation of the NTRUalgorithm for security of such application that is used for chats and showed that this algorithm provides the best security for android chatting application as well as systems chatting application. The keys generatedby the server are used for encryption/decryption of files and encrypted files are stored in the database. This paper focuses on implementation an algorithm for chat application on android.
