A Modified Simple Substitution Cipher With Unbounded Unicity Distance
finite-key unicity randomization
2019/6/4
The classic simple substitution cipher is modified by randomly inserting key-defined noise characters into the ciphertext in encryption which are ignored in decryption. Interestingly, this yields a fi...
On a Result of Tohge Concerning the Unicity of Meromorphic Functions
Meromorphic functions Weighted sharing Uniqueness
2008/6/27
In this paper we prove some uniqueness theorems of meromorphic functions which improve a result of Tohge and answer a question given by him. Furthermore, an example shows that the conditions of our re...
