A High Security Framework for SMS

As one of the most popular mobile communication technologies, short message service (SMS) is faced with various security threats. Thus, the fields of high confidentiality (e.g., mobile E-commerce) require a higher level of security protection on SMS. Secure communication in incredible mobile network has very important significance. This paper presents a high security framework for SMS. Through authentication, decryption and integrity protection, it establishes an end-to-end secure channel between server-side and mobile terminal. And it provides various secure application services in the channel. Through attack analysis and simulating a complete SMS system, this framework is proved to ensure confidentiality, integrity and non-repudiation of SMS messages.
