The concept of composition of finite automata is first proposed in finite automaton public key cryptosystem.
在有限自动机公开钥密码体制中首次提出了自动机化合的概念。
In the construction of cryptosystem of a pair of keys and cryptosystem which is based on identifcation,the composition of finite automata becomes a basic means.
主要讨论了有限自动机的化合与化合前两个有限自动机的弱可逆性,严格延迟步数,弱逆以及线性的一些关系。
It also discusses the invertibility of composition of FA.
主要讨论了有限自动机运算后的可逆情况,给出了有限自动机串、并联后为可逆(弱可逆,延迟有限步(弱)可逆)的若干条件,最后对有限自动机的化合运算的可逆性进行了特别讨论。
