This Paper's main contribution is confidentiality, integrity and authentication in SMS (Short Message Services). The transmission of an SMS in GSMnetwork is not secure, therefore it is desirable toSecure SMS by additional encryption. In the following text, thereare various algorithmsare compared in the use of cryptography for SMS transfer securing. The two main characteristics that identify and differentiate one encryption algorithm from another are its ability to secure the protected data against attacks by hackers and its speed and efficiency. This paper provides aPerformance comparison between five of the most common encryption algorithms: DES, 3DES, Blowfish, AES and NTRU. The comparison has been conducted by running several encryption settings to process different sizes of data blocksto evaluate the algorithm's encryption/decryption speed. Papers main concern here is the performance of thesealgorithms under different conditions, the presented comparison takes into consideration the behavior and performance of the algorithm when different data loads are used. Simulation has been conducted in JAVA J2ME platform and on android O.S. At the end, this paper present a new algorithm for enhancing the performance of available algorithm. The proposed method is faster on average than the best previously known method. This paper also present a highly efficient implementation of NTRU within the android CryptographyArchitecture
