• This letter gives a study of addition Y=X+K mod 2^w which is used in some cryptosystems as RC5. Our results enables us to express the differential and linear probability of addition as a function of addend K. To detect a good differential characteristics or linear approximation of a cryptosystem in which extended key is used as addend, we need to consider how the characteristics or approximations behave depending upon the value of the addend, which are clarified by our results.
