Detection and immunological relationship of yolk proteins from different parasitoid wasps

This paper discusses the cryptographical characteristic of output sequence of the additive combined generator,and points out the Output sequence has long period,large linear complexities,correlation-immunity,strong auto correlation and weak cross correlation.

First, this paper gives non-linearity and balanced correlation-immunity of Bent functions and non-repeated homogeneous functions with k degree respectively; second, deeply studies the applications of the two kinds of functions in constructing nonlinear combining functions.

The necessary and sufficient conditions of balanced ,correlation-immune and propagating partially-Bent functions are presented respectively, the nonlinear degree of partially-Bent functions and the equivalent probability of a partially-Bent function and an affine function are given in the paper.

The cryptographic properties of the k -order quasi-Bent functions, such as balancedness, correlation immunity, propagation criterion and the highest algebraic degree can all be easily decided only by the distributions of 0 and 1 in the character matrix, which is different from the spectrum method and the auto-correlation method.

Both balancedness and correlation immunity is one of the most important cryptographic characteristics of a Boolean function to which have gotten many researches respectively.

The relation between combining design and correlation immunity is discussed.
