摘　　要：研究手机通信系统中图文数据的加密设计,由于手机设备的有限性能,其运算能力还无法与计算机相提并论。因此文中采用具有高效率和轻量级特点的X-IDEA加密算法,它是对IDEA算法进行改良使之更适合运用于手机图文安全传送,也更适合与当前3G通信中图文大小可变以及存在相同部分的可能性增大的情况。This paper has studied the encryption of data in mobile＇s graphic communication,and the computing power cannot be compared with the computer due to the limited performance of mobile devices.Therefore,this paper uses a highly efficient and lightweight characteristics： X-IDEA encryption algorithm,it is a improved IDEA algorithm.This nalgorithm has improved IDEA more suitable transmission used in mobile graphics safe,more suitable the current variable size Photo in 3G,while the presence of an increased possibility of the same part of the case.
