Abstract


In this century, although the IP core reuse has solved the problem of the IP design difficult and design cost a long time, but the appearing of the IP core theft, illegal copying, reselling, and tampering is greatly hindered the development of the IP core market. Therefore the use of encryption technology to protect the IP core and providers to ensure that the interests of IP core based on the IP core for the majority of buyers and provide maximum convenience is a major problem to be solved to promote the healthy development of IP core market.Compared to other symmetric encryption algorithm, the Federal Government’s latest AES encryption algorithm used in reliability, high efficiency, saving resources have a greater advantage. Almost all of the studies show that the same level of security, in elliptic curve public key encryption algorithm, ECC encryption algorithm that takes the least resources, as its key short. Therefore, the AES encryption algorithm and ECC encryption algorithm for protecting IP core is the best choice.This paper used a symmetric key algorithm AES, using the Verilog language to achieve AES hardware encryption and decryption IP core module and the module is implemented in the encryption and decryption of resource sharing, saving chip area and improve the chip’s processing speed. Finally, the IP core embedded in the PS hardware and software collaborative platform FPGA, and successfully verified the IP core protection based on AES function of the system. In addition, this article uses the Verilog language to implement elliptic curve encryption algorithm hardware encryption and decryption IP core module, and so that it can work in prime fields and finite field operations of these two different domains, but also two different operations in this domain realized Resource sharing, and finally verified by the program. As the IP core in the ECC has no global clock, and there is no clock skew, chip function has been greatly improved.
