Combinatorial method for Boolean SAC functions designing
In this paper a new approach for designing Boolean functions that satisfy the Strict Avalanche Criterion (SAC) is presented. The advantage of the suggested approach is the simplicity of its realization and the significant greater number of the generated functions compared to the known methods. The formalized procedure for construction of nonbalanced and balanced SAC-functions is described in de...
متن کاملbuckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
A Simple, Artistic and Efficient Modification of the Inversion Method
The simplest and fastest way of producing an acceptable and accurate cast is by adopting the two-pour or inversion method. This process is slightly cumbersome and messy due to difficulty of access. A much more efficient, easy and artistic way of accomplishing it is described by adopting a Rotating Cake Icing Table with a Silicone Baking Mat on top as an autoclavable non-stick barrier.
متن کاملGeneralization of Higher Order SAC to Vector Output Boolean Functions
S-boxes (vector output Boolean functions) should satisfy cryptographic criteria even if some input bits (say, k bits) are kept constant. However, this kind of security has been studied only for scalar output Boolean functions. SAC(k) is a criterion for scalar output Boolean functions of this type. This paper studies a generalization of SAC(k) to vector output Boolean functions as the rst step t...
متن کاملAlmost Boolean Functions: The Design of Boolean Functions by Spectral Inversion
The design of Boolean functions with properties of cryptographic significance is a hard task. In this paper, we adopt an unorthodox approach to the design of such functions. Our search space is the set of functions that possess the required properties. It is ‘Booleanness’ that is evolved.
