The distribution of their correlation values is completely determined. These families have maximum correlation $2^{n/2+1}+1$ and family size $2^{3n/2}+2^{n/2}$ for odd $n/2$ or $2^{3n/2}+2^{n/2}-1$ for even $n/2$. The construction of the large set of Kasami sequences which is exactly the $\mathcal{F}^{k}$ with $k=n/2+1$ is generalized.30 pagesInformation TheoryCryptography and Securitytext
