At last, security and capability of the system are evaluated with methods of qualitative analysis and quantitative analysis; ways to enhance system's performance are also discussedThe main research results of this article are as follows: a solution including three security services to settle short message security threatens; discussing on algorithm set which includes ECC, AES, HASH, describing implement of the three security services by using the algorithm set; design and implement of secure short message protocol; modularizing design and coupling research between modules with guiding ideology of object oriented and reusability; put forward an design of short message engine which is used for encapsulation operations of short message.
