强壮的部分平衡的设计 SPBD (v, b, k;λ, 0 ) 其 b 是在所有 SPBD 的块的最大数(v, b, k;λ, 0 ) 作为一个最佳的强壮的部分平衡的图案,简短 OSPBD (v, k,λ) 被学习。在认证代码的调查,强壮的部分平衡的设计能被用来构造认证代码,这被发现了。这笔记调查最佳的强壮的部分平衡的设计 OSPBD 的存在(v, k, 1 ) 为 k = 在那里存在的 3 and4,和表演 OSPBD (v, k, 1 ) 为任何 v ≥ k。
A strong partially balanced design SPBD(v, b, k; λ,0) whose b is the maximum number of blocks in all SPBD(v, b, k; λ, 0), as an optimal strong partially balanced design, briefly OSPBD(v, k, λ) is studied. In investigation of authentication codes it has been found that the strong partially balanced design can be used to construct authentication codes. This note investigates the existence of optimal strong partially balanced design OSPBD(v, k, 1) for k = 3 and 4, and shows that there exists an OSPBD(v, k, 1) for any v ≥ k.
