- We all know in Caesar cipher we replace each alphabet with other alphabet which is 3 positions down the order. Modified Caesar cipher is same as actual Caesar cipher with little modification.
- We are now saying that alphabet A will not necessarily replace by alphabet D. It can be replaced by any other valid alphabet i.e. by E,F,G and so on, there are 25 other alphabets with whom we can replace alphabet A. Once replacement scheme is decided then it would be constant and will be use to replace other alphabets in that message.
- There are only 25 other combinations because there are 26 alphabets in English and it doesn’t make sense to replace it with himself.
- Hence to break modified Caesar cipher our earlier algorithm would not work but it is still weak encryption method.
