title = "Related-key attacks on the full-round Cobra-F64a and Cobra-F64b",
abstract = "Cobra-F64a and Cobra-F64b, designed for firmware-oriented applications, axe 64-bit Data-dependent Permutation based block ciphers with 128 key bits, which consist of 16 and 20 rounds, respectively. In this paper, we investigate their security against related-key attacks. Our investigation shows that the full 16-round Cobra-F64a can be broken by our related-key rectangle attack and that the full 20-round Cobra-F64b can be broken by our related-key differential attack.",
