Abstract: Nowadays, short message communication has a wide range of applications in modern lives. Authentication, announcements, reports, and personal communications are the common instances of application of this widely used digital media. At transmission time, the message content spreads in the air without any intrinsic security countermeasure. As a result, the content of messages is interceptable without the need for complicated equipment. In modern methods, security has migrated from hardware to software, especially in smartphones. In this research, a method for securing short message communications is introduced which uses four distinguished cryptographic key generation factors to produce a couple of unique and dynamic encryption and decryption keys. The evaluation results show that the proposed method uses secure encryption and decryption keys, is resistant against a wide range of cryptographic and network attacks, outstandingly reduces the cost of establishing secure sessions, and highly satisfies the users with the delivered level of security and usability.
