Some applications of finite BL-algebras

In this paper we present an encryption/decryption algorithm which use properties of finite MV-algebras, we proved that there are no commutative and unitary rings R such that Id ® = L,where L is a finite BL-algebra which is not an MV-algebra and we give a method to generate BL-comets. Moreover, we give a final characterisation of finite BL-algebra and we proved that a finite BL-algebra is a comet or MV-algebras which are not chains.
