The Key Exchange Research of Chaotic Encryption Chip Based on Elliptic Curve Cryptography Algorithm

In order to encrypt the plaintext information with FPGA encryption chip based on chaotic encryption algorithm, the elliptic curve cryptography algorithm is applied to encrypt and transmit the initial key to realize secure exchange. This essay emphatically researches the improvement of the point multiplication and the subjacent multiplication operations of the elliptic curve encryption so as to speed up the system implementation. Finally, the concerned experimental simulation of the improved elliptic curve encryption system proves that the system can effectively realize the security exchange of chaotic initial key.
