Cryptosystem with Rédei Rational Functions via Pellconics
2012
International Journal of Computer Applications
In this paper, two cryptosystems are constructed using the fact that Rédei rational functions are permutation polynomials and exploiting the multiplicative properties of Rédei rational functions and the inverse property of Dickson polynomial extended to Rédei rational functions. The encryptions are based on evaluating Rédei rational functions ( , ) kn Q d z ¢ with the values n z ¢ connected to the solutions of the Pell's equation 22 1 x dy in n ¢ . The connection between these evaluations
