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...
The encrypting time of traditional AES algorithm is too long to meet the need of fast encryption. For this point, the high-performance computing capability of Graphic Processing Unit has become the hot issue of research. This paper proposes that AES algorithm is improved by use of GPU's high performance computing capability and compared with that using CPU. And AES encryption algorithm base on high...
