Cryptosystems with Rédei Rational Function via Pellconics
P. Anuradha Kameswari, R. Chaya Kumari · 2012
In this paper, two cryptosystems are constructed using the fact that Redei rational functions are permutation polynomials and exploiting the multiplicative properties of Redei rational functions and the inverse property of Dickson polynomial extended to Redei rational functions. The encryptions are based on evaluating Redei rational functions ( , ) kn Q d z ¢
