Truncated and Higher Order Differentials
In 6] higher order derivatives of discrete functions were considered and the concept of higher order diierentials was introduced. We introduce the concept of truncated diierentials and present attacks on ciphers presumably secure against diierential attacks, but vulnerable to attacks using higher order and truncated diierentials. Also we give a differential attack using truncated diierentials o...
متن کاملThese are your rights.
over centuries, the labour move ment fought to establish basic rights for workers, combatting the vested interests of avaricious capital ists and the cynicism of the state, which consigned to the workhouse those unable to find employment in the mines and fac tories. through collective action in the form of trades unions, then later through the political parties that were established in their...

High-order Point Variations and Generalized Differentials
In a series of nonsmooth versions of the Pontryagin Maximum Principle, we used generalized differentials of set-valued maps, flows, and abstract variations. Bianchini and Stefani have introduced a notion of possibly high-order variational vector that has the summability property. We consider a slightly more general class of variational vectors than that defined by Bianchini and Stefani, and pro...
متن کاملFrom Higher-Order Differentials to Polytopic Cryptyanalysis
Polytopic cryptanalysis was introduced at EUROCRYPT 2016 as a cryptanalytic technique for low-data-complexity attacks on block ciphers. In this paper, we give an account of how the technique was developed, quickly go over the basic ideas and techniques of polytopic cryptanalysis, look into how the technique differs from previously existing cryptographic techniques, and discuss whether the attac...
