Construction of efficient and secure Pairing Algorithm and its Application
The randomized projective coordinate (RPC) method on pairing computing algorithm is a good solution which leads an efficient countermeasure against side channel attacks. In this paper, we investigate measures for the efficiency of the RPC based countermeasures of the pairing algorithm and construct a method that induce an efficient RPC based countermeasure against side channel attacks. As it application, we apply our construction method to the well-known $\eta_T$ pairing algorithm over binary fields and so we obtain an RPC based countermeasure of $\eta_T$ pairing which is more efficient than the RPC method on the original $\eta_T$ pairing algorithm.
