This paper has made some discussions on the finite commutative semigroup. The relationship between the finite commutative semigroup and the finite commutativegroup is established.

First, we give the definition of Lie color superalgebras using the symmetric bicharacter on a finite commutativegroup, and also we introduce some fundamental notions about Lie color superalgebras.
The braid group is infinite non-commutativegroup, and it has many hard problems that can be utilized to design cryptographic primitives, such as the word problem, conjugacy problem and root problem.
