KT-64 is a 64-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 2^(45∙5) related-key chosen plaintexts and 2^(65∙17) KT-64 encryptions. This work is the first known cryptanalytic result on KT-64.
