A hash function may use a block cipher algorithm as its basic structure to improve the efficiency and cost of hardware and software implementation. The SIMON, SPECK, and SIMECK algorithms are a family of lightweight block ciphers designed for implementation on devices with constrained resources. In this paper, we examine the robustness of the Davies-Meyer scheme using the SIMON-32, SPECK-32, and SIMECK-32 algorithms as the basic structure using fixed-point attacks. The result obtained is that the Davies-Meyer scheme based on SIMON, SPECK, and SIMECK algorithms shows the vulnerability to fixed-point attacks.
