A Construction of 1-Resilient Boolean Functions with Good Cryptographic Properties

摘要

This paper proposes a general method to construct 1-resilient Boolean functions by modifying the Tu-Deng and Tang-Carlet-Tang functions.Cryptographic properties such as algebraic degree,nonlinearity and algebraic immunity are also considered.A sufficient condition of the modified functions with optimal algebraic degree in terms of the Siegenthaler bound is proposed.The authors obtain a lower bound on the nonlinearity of the Tang-Carlet-Tang functions,which is slightly better than the known result.If the authors do not break the "continuity" of the support and zero sets,the functions constructed in this paper have suboptimal algebraic immunity.Finally,four specific classes of 1-resilient Boolean functions constructed from this construction and with the mentioned good cryptographic properties are proposed.Experimental results show that there are many 1-resilient Boolean functions have higher nonlinearities than known 1-resilient functions modified by Tu-Deng and Tang-Carlet-Tang functions.
