构造具有良好性质的伪随机序列一直是密码学研究的热点问题之一。基于有限域上的椭圆曲线构造了一类二元伪随机序列,并利用椭圆曲线上的指数和计算了该类序列的一致分布测度和k阶相关测度。结果表明该类序列具有较小的一致分布测度和k阶相关测度。
It is one of the hot-spots in cryptography to construct pseudorandom sequences with good properties.This paper presents a family of pseudorandom binary sequences constructed from elliptic curves over finite fields.With the help of exponential sums on elliptic curves,the well-distribution measure and correlation measure of order k are computed.The results show that both of them are small.
