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.
