Higher order differential (HOD) attack and Integral attack are one of the general purpose attacks to common key block ciphers. The former uses the concept of recursive application of differential of discrete functions, and the latter uses the XOR sum property of discrete functions.
As HOD can be also expressed as XOR-sum formula, they are very similar, but Integral attack has a wider concept.
Todo introduced the Division property as the method to find good integral characteristic.
This article uses the Division property as a link of HOD and Integral, and shows the followings.
The best Integral attack derived by Division property is equal to the HOD attack. The data complexity is the same; both needs $2^{d+1}$ texts for non-linear function $f(Vec{x})$ of degree $d$.
The number of different characteristics is the same for both attacks.
It is $2^{m-d-1}prod ^d_{i=0}frac{2^{m-i}-1}{2^{d-i}-1}$, where $m$ is a input width of $f(Vec{x})$.
These results are derived from the minimum distance and weight distribution of RM codes. |
