Abstract

In applications such as communications and cloud storage

electronic files encryption is an important way to enhance information security and prevent cyber theft. A new encryption scheme and its hardware realization are proposed. First

two 3-D discrete time chaotic systems based on chaos anti-control theory are designed. Then each variable from these two chaotic systems is multiplied and molded

and the results are used to encrypt files. Security analysis is finally conducted. To keep the encrypted file remaining in its original format

the encryption system only encrypts the file data section but not the file format section

so that it avoids the format compatibility problems caused by format corruption. The encryption system is implemented mainly based on a SOPC (System on a Programmable Chip)

while the encryption algorithm is achieved in FPGA (Field Programmable Gate Array) and the Ethernet communication is realized in ARM (Advanced RISC Machines). Experiment results show that the electronic files are encrypted and decrypted correctly and the format is compatible

and thus experiment results present the favorable security performance and the technical feasibility.
