The main contributions of the second part of this dissertation are focused on the cryptographic properties of logical functions over finite field, with the help of the properties of trace functions, and that of p-polynomials, as well as the permutation theory over finite field: The new definition of Chrestenson linear spectrum is given and the relation between the new Chrestenson linear spectrum and the Chrestenson cyclic spectrum is presented, followed by the inverse formula of logical function over finite field; The distribution for linear structures of the logical functions over finite field is discussed and the complete construction of logical functions taking on all vectors as linear structures is suggested, which leads to the conception of the extended affine functions over finite field, whose cryptographic properties is similar to that of the affine functions over field GF (2) and prime field F〓; The relationship between the degeneration of logical functions and the linear structures, the degeneration of logical functions and the support of Chrestenson spectrum, as well as the relation between the nonlinearity and the linear structures are discussed; Using the relation of the logical functions over finite field and the vector logical functions over its prime field, we reveal the relationship between the perfect nonlinear functions over finite field and the vector generalized Bent functions over its prime field; The existence or not of the perfect nonlinear functions with any variables over any finite fields is offered, and some methods are proposed to construct the perfect nonlinear functions by using the balanced p-polynomials over finite field.

Evanescence: Taking Over Me You don't remember me, but I remember you I lie awake and try so hard not to think of you But who can decide what they dream, and dream I do I believe in you I'll give up everything just to find you I have to be with you To live, to breathe You're taking over me Have you forgotten all I know, and all we had You saw me mourning my love for you, and touched my hand I knew you loved me then I believe in you I'll give up everything just find you I have to be with you To live, to breathe You're taking over me I look in the mirror and see your face If I look deep enough So many things in side that are Just like you are taking over I believe in you I'll give up everything just to find you I have to be with you To live, to breathe You're taking over me I believe in you I'll give upeverything just to find you I have to be with you To live, to breathe You're taking over me You're taking over me You're taking over me

你不记得我，但我记得你我躺着努力不去想你但是谁能决定他们的梦呢，我也一样我相信你我要放弃一切只为找到你只有和你在一起才能生存，才能呼吸你是我的全部你忘了我们的从前么你看到我为你哀悼我的爱，你触碰我的手我知道你是爱我的我相信你我要放弃一切只为找到你只有和你在一起才能生存，才能呼吸你是我的全部我在镜子里看到了你的脸我仔细的看我发现有很多东西正如你占据着我一样我相信你我要放弃一切只为找到你只有和你在一起才能生存，才能呼吸你是我的全部我相信你我要放弃一切只为找到你只有和你在一起才能生存，才能呼吸你是我的全部你是我的全部你是我的全部我自己翻的就这样啦您凑合着看看吧

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.
