embedded authentication cryptanalysis

Breaking a simple 128 bit authentication algorithm of an embedded device. The host sends message X: 128 bit to the device, device responds to host with message Y: 128 bit as a function Y=f(X). The algorithm is fast, thus simple (takes few microseconds to compute on an embedded microcontroller). We need to find the algorithm f(). We can pass any sequence of data X to produce Y for cryptanalysis methods. An example is attached.

Hello, Do you have host sided program? Then I can do reverse engineering work and find out the algorithm. Thanks

Algorithm can be obtained by analyzing host-side software or device-side software. Do you have access to at least one of them? There are very low chance to find algorithm using valid pairs only.
