Construction of Transition Matrices for Ternary Ring Feedback With Carry Shift Registers


Since the linear structure of linear feedback shift registers (LFSRs) has a drawback that may lead to attacks against LFSR-based stream ciphers, feedback with carry shift registers (FCSRs) have been proposed as an alternative to LFSRs for the design of stream ciphers. However, some weaknesses in stream ciphers based on Fibonacci or Galois FCSRs have been… (More)
