Partitioned Soft Sets and Their Application to Cryptology

Soft set theory, introduced by Molodtsov in 1999, is a mathematical tool for dealing with uncertainty and vagueness in a parameterized way. Cryptology is a method of protecting information and communications so that only those for whom the information is intended can read and process it. In this article, we defined partitioned soft sets, which represent a new concept in soft set theory. Using these partitioned soft sets, we then constructed a new type of cipher method called a soft cipher. It is a variation of a cipher method. Finally, we developed a computer program with examples for the soft cipher method.
