olemus
(1) ründe ressursitarbe mõõt,
näiteks ründevahendite või -teenuste ostuhind
= cost of tools or services for attack

ISO/IEC 18033:
ründe keskmise töömahu suhe
rünnatava algoritmi kutsete arvu ja
ründe õnnestumise tõenäosuse korrutisse,
st suhe W/P, kus
- W on ründealgoritmi keskmine keerukus
krüpteerimisalgoritmi kutsete arvuna
- P on ründe õnnestumise tõenäosus
krüptoründe toime otsustamisel
võivad olla olulised ka muud
hinna mõõdud ja omadused, näiteks
mälu keerukus, andmete keerukus, riistvaraga või rööbitusega kiirendamise võimalikkus
=
ratio of the average workload of the attack to an equivalent number of calls to the encryption algorithm under attack multiplied by the success probability of the attack
Note 1. Using the notation defined in Clause 4, the attack cost is equal to the ratio W/P.
Note 2. Other attack cost metrics and properties, such as memory complexity, data complexity, the ability to be accelerated by specialized hardware or parallelizability may also be important in judging the impact of a cryptographic attack.
