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.

Positive correlation between Mg~# and P_2O_5 and negative correlation between P_2O_5 and FeO suggest that addition of P is not the key role for the separation of immiscible oxide melts. In contrast, negative correlation between Mg~# and Fe_2O_3/FeO ratios implies that the increasing of oxygen fugacity is very likely the main factor to induce immiscibility of oxide melt.

Mg#与P2O5的正相关以及P2O5与FeO含量的负相关，表明P不是导致氧化物熔体不混熔的主要原因；而Mg#与Fe2O3/FeO的负相关则说明，岩浆演化过程中氧逸度的升高可能是导致氧化物熔体不混熔的主要原因。

In this technique, K-L transformation was used to remove spectral statistic correlation on the spectral direction. Then SNMAW prediction tree technique was used to remove spatial correlation and spectral structure correlation.
