چکیده

Elliptic curve cryptosystems, proposed by Koblitz([8]) and Miller([11]), can be constructed over a smaller definition field than the ElGamal cryptosystems([5]) or the RSA cryptosystems([16]). This is why elliptic curve cryptosystems have begun to attract notice. There are mainly two types in elliptic curve cryptosystems, elliptic curves E over IF2r and E over IFp. Some current systems based on ElGamal or RSA may often use modulo arithmetic over IFp. Therefore it is convenient to construct fast elliptic curve cryptosystems over IFp. In this paper, we investigate how to implement elliptic curve cryptosystems on E/IFp.

Efficient elliptic curve cryptosystems

Elliptic curve cryptosystems (ECC) are new generations of public key cryptosystems that have a smaller key size for the same level of security. The exponentiation on elliptic curve is the most important operation in ECC, so when the ECC is put into practice, the major problem is how to enhance the speed of the exponentiation. It is thus of great interest to develop algorithms for exponentiation...

An Efficient Procedure to Double and Add Points on an Elliptic Curve

We present an algorithm that speeds exponentiation on a general elliptic curve by an estimated 3.8% to 8.5% over the best known general exponentiation methods when using affine coordinates. This is achieved by eliminating a field multiplication when we compute 2P + Q from given points P , Q on the curve. We give applications to simultaneous multiple exponentiation and to the Elliptic Curve Meth...

A Novel Multi Exponentiation Method

The efficiency and security of most elliptic curve cryptosystems are based on multi exponentiation, such as the verification process in elliptic curve digital signature algorithm. Simultaneous methods are considered to be the most efficient for multi exponentiation. In this paper, we propose a method to construct an addition chain for simultaneous multi exponentiation, which has never been cons...
