Construction and Analysis of Extended Welch-Gong Sequences
Abstrak
Welch-Gong(WG) sequences have good randomness,including long period,balance property,ideal 2-tuple distribution,two-level autocorrelation,three-level cross correlation with m-sequences,and linear complexity increasing exponentially.For the WG transformation,the odd term of polynomial function is studied.Considering the complexity of polynomial function by WG transformation,this paper extends the specific five-term function to general three-term function in WG transformation,and analyzes that the new sequences still have good randomness and low linear complexity.It selects a specific instance to analyze the hardware implementation of WG cipher based on the three-term function,and gives a certain reference value for the design of the algorithm.
