| Abstract: | In order to encrypt the plaintext information with FPGA encryption chip based on chaotic encryption algorithm, the Elliptic Curve Cryptography algorithm is applied for the encryption and transmission of the initial key. Thus, the initial key of chaotic encryption chip is securely exchanged. This essay emphatically reseaches 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. |
