中文摘要:

单身者产生的四种序列骑车三角形的功能(T 功能) 被调查为是在流零的一个密码的部件的单个周期 T 功能检查可能性。由于魏,基于单个周期 T 功能和一个算法的特殊性质这些的线性复杂性四种顺序都被获得。结果证明单个周期 T 功能序列有高线性的复杂性。因此, T 功能满足是溪流零的一个基本部件的必要要求。

英文摘要:

Four kinds of sequences generated by single cycle triangular function (T-function) are investigated to check the possibility for a single cycle T-function to be a cryptographic component in stream ciphers. Based on the special properties of single cycle T-function and an algorithm due to Wei, linear complexities of these four kinds of sequence are all acquired. The results show that single cycle T-function sequences have high linear complexity. Therefore, T-function satisfies the essential requirements being a basic component of stream cipher.
