在不存在分裂的情况下,提供保密性和认证性的认证码和保密码已经被深入研究;然而,关于存在分裂的情况的结果要少得多。在本文中,我们重点研究了c-分裂的情况,并得到了获得最大安全级别所需的编码规则数量的一个界。如果C-分裂认证和保密代码获得最大安全级别并且具有最小数量的编码规则,则该代码称为最优。我们定义了一种新的设计,称为认证垂直多阵列,并证明了认证垂直多阵列的存在意味着存在最优的c-分裂认证和保密码。进一步,我们研究了认证垂直多阵列的结构和存在性,得到了两类新的无限类最优c-分裂认证和保密码。
Authentication and secrecy codes which provide both secrecy and authentication have been intensively studied in the case where there is no splitting; however the results concerning the case where there is splitting are far fewer. In this paper, we focus on the case with c-splitting, and obtain a bound on the number of encoding rules required in order to obtain maximum levels of security. A c-splitting authentication and secrecy code is called optimal if it obtains maximum levels of security and has the minimum number of encoding rules. We define a new design, called an authentication perpendicular multi-array, and prove that the existence of authentication perpendicular multi-arrays implies the existence of optimal c-splitting authentication and secrecy codes. Further, we study the constructions and existence of authentication perpendicular multi-arrays, and then obtain two new infinite classes of optimal c-splitting authentication and secrecy codes.
