本文研究了通信系统中重要的 Costas阵列。对多值逻辑函数提出了处处非线性函数 ,并揭示出 Costas阵列与处处非线性函数深刻的内在联系。证明了一个 Costas阵列就是一个对称或负对称的正交拉丁方阵。将Costas阵列引入密码学中的公开钥密码系统 ,极大地提高了系统破译的难度
This article studies the important Costas arrays in communication systems. Proposed a non-linear function for multi-valued logic functions everywhere, and revealed a deep intrinsic relationship between Costas array and non-linear functions everywhere. Prove that a Costas array is a symmetric or negatively symmetric orthogonal Latin square. Introducing the Costas array into the cryptographic public key cryptosystem greatly increases the difficulty of system deciphering
