2011 Fourth International Workshop on Chaos-Fractals Theories and Applications ARM Realization of Storage Device Encryption Based on Chaos and AES Algorithm Chunlei Wang, Guangyi Wang School of Electronics Information Hangzhou Dianzi University Hangzhou, China e-mail: chunle163.com Yue Sun and Wei Chen School of Electronics Information Hangzhou Dianzi University Hangzhou, China ail: wanggyi@163.com  Abstract—In order to improve the security of the private information in memorizer, an encryption algorithm, which inherits the advantages of chaotic encryption, stream cipher and AES algorithm, is proposed in this paper. We design and realize an encryption system based on the algorithm on ARM(S3C6410), which can encrypt and decrypt the show how it generates the keys. The equation (1) gives the switch hyperchaos as below: ??dx ??dt ??a( y ??x) ? ??dy information in many kinds of memorizers, such as UDisk, SD card and mobile HDD. The system that uses Human-Computer Interaction and Visualization technology provides several encryption algorithms and key generators. Some analysis results are presented to show its high security at the end of the paper. ??dt ???dS (x)x ??cy ??xz ? u ? ??dz ??xy ??bz ??dt ??du ?????????kx ??dt (1) Where a, b, c, d and k are constant parameters. Keywords-chaos; stream cipher; AES; ARM; storage device When x ??0 , S (x) ??1 ; while S (x) ??0 when x ??0 . Take the parameters a ??35 , b ??3 , c ??20 , d ??5 and INTRODUCTION With the development of the digital devices, computers and networks, our world relies more and more on the digital data. In many cases, storing data safely is a very big concern. These data have to be protected so as to prevent the possible unauthorized access. Many technologies have been used to improve the security of the data storage. Such as authentication, audit trail and access control [1]. But all of these models have not encrypted the original data, once the
