abstract：There has been a recent surge of interest in Nonlinear Feedback Shift Registers (NLFSRs) which can aid the development of new hardware-oriented stream cipher designs especially for constrained applications such as RFID in IoT. In this talk, I will present some results from on cryptanalysis and efficiency of the encryption operations. Specifically, I discuss the relationship between Fibonacci and Galois configurations and their effect on generation and cryptanalysis of Ultra lightweight Grain and Fruit families.
