Abstract:

Conic curve cryptosystem was first introduced by CAO Zhenfu in 1998. By now, the previous study on conic curve cryptosystem has been based on conic curve group in finite field GF(p). Since the hardware circuits are suitable for performing addition, multiplication, squaring and the inversion operations in a finite field GF(2n), the operations in finite field GF(2n) are typically easier to implement in hardware and software than their counterpart in finite field GF(p). In order to speed up the computation of conic curve cryptosystem, the conic curve group is extended from finite field GF(p) to finite field GF(2n), and the order of the conic curve group in finite field GF(2n) is given. In addition, this paper suggests to use conic curve group in finite field GF(2n) for realizing public-key cryptosystem, and presents the basic ElGamal public-key encryption scheme and the Digital Signature Algorithm (DSA) based on conic curve in finite field GF(2n). Security of public-key cryptosystem based on conic curve in finite field GF(2n) is analyzed.
