In a recent work, a family of rational maps identified as tangent-Chebyshev maps over finite fields was introduced. Such maps have potential applicability in cryptography and channel coding. In this paper, we present new properties for the referred maps: their symmetry and fixed points are determined, their relationships with other maps are described and their functional graphs are characterized. Illustrative examples related to the developed properties are given; in particular, we show that the use of the referred maps to interleave in a turbo code may provide coding gains, when compared with usual approaches.
