By its nature, the SMS communication is insecure and the message information can be viewed of many interested parties. Here we propose a protocol for secure SMS end-to-end communication between two mobile devices. Our protocol is based on a symmetric encryption of the message context and on secure key exchange. The security of our protocol is based on the usage of already secure cryptographic algorithms:AES, SHA-2, DH-EC, and others.We have considered several possible attacks on our secure protocol and we could conclude that it is resistant of them.
