Security Analysis of Block Cipher KT-64 Jinkeon Kang

KT-64 is a -bit block cipher which use CSPNs suitable for the efficient FPGA implementation. In this paper, we propose a related-key amplified boomerang attack on the full-round KT-64. The attack on the full-round KT-64 requires  related-key chosen plaintexts and  KT-64 encryptions. This work is the first known cryptanalytic result on KT-64.
