# Multidimensional zero-correlation linear cryptanalysis of the block cipher KASUMI

@article{Yi2014MultidimensionalZL, title={Multidimensional zero-correlation linear cryptanalysis of the block cipher KASUMI}, author={Wentan Yi and Shaozhen Chen}, journal={IET Inf. Secur.}, year={2014}, volume={10}, pages={215-221} }

The block cipher KASUMI is widely used for security in many synchronous wireless standards. It was proposed by ETSI SAGE for usage in 3GPP (3rd Generation Partnership Project) ciphering algorthms in 2001. There are a great deal of cryptanalytic results on KASUMI, however, its security evaluation against the recent zero-correlation linear attacks is still lacking so far. In this paper, we select some special input masks to refine the general 5-round zero-correlation linear approximationsâ€¦Â
