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.

重新定义了有限域上逻辑函数的Chrestenson线性谱，考察了新定义的Chrestenson线性谱和原来的Chrestenson循环谱的关系，并利用一组对偶基给出了有限域上逻辑函数的反演公式；给出了有限域上随机变量联合分布的分解式，并利用随机变量联合分布的分解式对有限域上逻辑函数的密码性质进行了研究；给出了有限域上逻辑函数与相应素域上向量逻辑函数的关系，探讨了它们之间密码性质的联系，如平衡性，相关免疫性，扩散性，线性结构以及非线性度等；讨论了有限域上逻辑函数各类线性结构之间的关系，并给出了任意点都是线性结构的逻辑函数的全部构造，由此引出了有限域上的"泛仿射函数"的概念；考察了有限域上逻辑函数的退化性与线性结构的关系、退化性与Chrestenson谱支集的关系；给出了有限域逻辑函数非线性度的定义，利用有限域上逻辑函数的非线性度与相应素域上向量逻辑函数非线性度的关系，考察了有限域上逻辑函数的非线性度与线性结构的关系；利用有限域上逻辑函数与相应素域上向量逻辑函数的关系，揭示了有限域上的广义Bent函数与相应素域上的广义Bent函数的关系，以及有限域上的完全非线性函数与相应素域上向量广义Bent函数之间的关系；给出了任意有限域上任意n元完全非线性函数存在性与否的完整证明，并利用有限域上平衡的p-多项式的性质给出了有限域上完全非线性函数的一些基本构造方法。

Hotel brokers dragged staggering pace, with a look of exhaustion luggage into the station, one that is open to police to borrow money that is太岁头上动土encountered fraud syndicate, police did not believe the beginning, after the investigation turned out that name of the hotel brokers before working in Hong Kong to Taichung, after work has been unable to find a new job, spend money and helpless body, and want to go home but no money to ride, forced only to adults for help we the Boli Shi, raising more than 500 police vehicles block the money to the hotel brokers , good people to do in the end, and also patrol car with the hotel brokers to the station to ride bow deeply to the police adult Thank you kindly, hotel broker promised to find a job after returning Kaohsiung made money, some Taichung peace will return to the police station to thank the police who help him.

酒店经纪拖著蹒跚的步伐，带著行李一脸疲惫走进派出所，一开口就是要向员警借钱以为是太岁头上动土，遇到了诈骗集团，员警一开始还不相信，事后调查原来这名酒店经纪日前到台中港打工，工作结束后一直找不到新的工作，无奈身上的钱又花光了，想回家却没钱坐车，不得已只好向咱们的波丽士大人求助了，员警集资五百多块的车钱给酒店经纪，好人做到底，同时还用巡逻车载酒店经纪到车站搭车深深一鞠躬谢谢好心的警察大人，酒店经纪允诺回高雄后找到工作赚了钱，一定会回台中安宁派出所来谢谢帮助他的员警们。
