Improved Cryptanalysis of SHAMATA-BC
Adem Atalay Orhun Kara Ferhat Karakoç
We state the design flaws of the 1-round block cipher SHA\-MATA-BC, designed by Fleishmann and Gorski by using the building blocks of SHAMATA hash function. We fix the flaws and then show that the amended version of SHAMATA-BC is much weaker. We believe that there is no connection between security level of SHAMATA as a hash function and that of SHAMATA-BC as a block cipher.
