Research on Image-Text Encryption Techniques in Mobile Communications

This paper describes graphic-text files encryption in real-time mobile communication system. As the limited performance of mobile devices, the computing power can not be compared with the computer. Therefore, this paper uses a highly efficient and lightweight characteristics of X-IDEA encryption algorithm, which is the in proved IDEA algorithm, and modified to make it more suitable for secure transmission of graphic-text used in mobile phones, and more suitable for 3G communication with the current variable size Photo and the presence of an increased possibility of the same part of the case.
