This dissertation investigates the construction of pseudo-random sequences (pseudo-random numbers) from elliptic curves and mainly analyzes their cryptographic properties by using exponential sums over rational points along elliptic curves. The main results are as follows:(1) The uniform distribution of the elliptic curve linear congruential generator is discussed and the lower bound of its nonlinear complexity is given.(2) Two large families of binary sequences are constructed from elliptic curves. The well distribution measure and the correlation measure of order k of the resulting sequences are studied. The results indicate that they are "good" binary sequences which give a positive answer to a conjecture proposed by Goubin et al.(3) A kind of binary sequences from an elliptic curve and its twisted curves over a prime field F_p. The length of the sequences is 4p. The "1" and "0" occur almost the same times. The linear complexity is at least one-fourth the period.(4) The exponential sums over rational points along elliptic curves over ring Z_ are estimated and are used to estimate the well distribution measure and the correlation measure of order k of a family of binary sequences from elliptic curves over ring Z_.(5) The correlation of the elliptic curve power number generator is given. It is proved that the sequences produced by the elliptic curve quadratic generator are asymptotically uniformly distributed.(6) The uniform distribution of the elliptic curve subset sum generator is considered.(7) We apply the linear feedback shift register over elliptic curves to produce sequences with long periods. The distribution and the linear complexity of the resulting sequences are also considered.

本文研究利用椭圆曲线构造的伪随机序列，主要利用有限域上椭圆曲线有理点群的指数和估计讨论椭圆曲线序列的密码性质——分布、相关性、线性复杂度等，得到如下主要结果：(1)系统讨论椭圆曲线-线性同余序列的一致分布性质，即该类序列是渐近一致分布的，并给出了它的非线性复杂度下界；(2)讨论两类由椭圆曲线构造的二元序列的"良性"分布与高阶相关性(correlation of order κ)，这两类序列具有"优"的密码性质，也正面回答了Goubin等提出的公开问题；(3)利用椭圆曲线及其挠曲线构造一类二元序列，其周期为4p(其中椭圆曲线定义在有限域F_p上)，0-1分布基本平衡，线性复杂度至少为周期的四分之一；(4)讨论了剩余类环Z_上的椭圆曲线的有理点的分布估计，并用于分析一类由剩余类环Z_上椭圆曲线构造的二元序列的伪随机性；(5)讨论椭圆曲线-幂生成器序列的相关性及椭圆曲线-二次生成器序列的一致分布；(6)讨论椭圆曲线-子集和序列的一致分布；(7)讨论椭圆曲线上的线性反馈移位寄存器序列的分布，线性复杂度等性质。

The Joseph father advantage takes a bath the number of times are not many, the approximately 23 weeks only then flush one time then to be possible, but the pet owner cannot be therefore loaf, still importantly recorded scratches every day for the dog class throws over the wool, can make to throw over the wool maintains along slides sharp; Because the Joseph bottomless wool level, throws over the wool in addition inborn along the straight relations, therefore throws over the situation which the wool very little appears ties a knot, in after dog flushing body, must thoroughly and eats Mao Mogan does, uses the unraveling to comb again combs the wool cascade is suitable, because the dog throws over the wool young, therefore in combing time then must double carefully, combs by suitable Canada, only then not Mao Shuduan, if needs, may use unraveling unrefined oil, when carding wool then did not fear that sleepy wrong with adds makes the painful dog; Because throws over the wool the fat secretion to be many, the ear easy Tibet dirt, skin also Yi Sheng to have the tinea, must therefore maintain the body clean clean.

补充约瑟爹利洗澡的次数不多，约两三星期才冲洗一次便可，但饲主也不能因此而偷懒，仍要紧记每天为狗儿流擦披毛，才能令披毛保持顺滑亮丽；由於约瑟无底毛层，加上披毛天生顺直的关系，所以披毛很少出现打结的情形，在替狗儿冲洗身体后，要彻底把毛抹乾及吃乾，再用解结梳把毛逐层梳顺，因为狗儿的披毛较幼，所以在梳理时便要加倍小心，以适当的加度去梳，才不把毛梳断，如需要的话，更可使用一解结毛油，梳毛时便不怕困错用加而弄痛狗儿；由於披毛的脂分泌较多，耳朵易藏污垢，皮肤亦易生有癣疥，所以要保持身体清洁乾净。约克夏狗是狗类型一个小狗品种，开发在19世纪在约克夏历史地区在英国。品种的定义的特点是它的小型和它柔滑的蓝色和棕褐色的外套。品种起绰号Yorkie和安置在狗小组的玩具狗部分由Fédération Cynologique国际歌和在玩具小组或伴侣小组由其他狗窝俱乐部，虽然所有同意品种是狗。一赢取的showdog和一条普遍的伴侣狗，约克夏狗也是其他品种的发展的一部分，例如澳大利亚柔滑的狗。
