Milos V. Bandjur · Facta universitatis - series Electronics and Energetics · 2003
Systems for ciphering contain substitution or transpositions or combination of both. The goal of the present work is to suggest the new cipher that belongs to substitutional ciphers with constant cryptogram length, where cryptogram length is equal with message length. Cipher system suggested here is new and belongs to perfect cipher class regarding the aspect of reliability, as will be shown.
