摘要
参考文献 [1 ]中首次提出了拟 Bent函数的概念 .在本文中 ,我们进一步研究了这一类函数的性质及它与 Bent函数的关系 .当 n=4时 。
The definition of quasi\|Bent function is first presented in \. In this paper, we study more properties of this kind of function and its relationship with Bent function. As for n=4, we do a further research on its cryptographic properties if it were used as cryptographic function.
