Abstract

We will describe an algorithm to construct an elliptic curve EfqE_{f_q} over some prime field Fp\mathbb{F}_p such that such that Efq(Fp)=fq|E_{f_q}(\mathbb{F}_p)| = f_q, where fqf_q is a probable Fibonacci prime for some prime index qq. The algorithm is a variant of the efficient CM-construction by Bro¨\ddot{o}ker and Stevenhagen, which is well suited for Fibonacci primes due to their arithmetic properties. The time complexity of our algorithm is expected to be lower than O~(log3(fq))\widetilde{O}(\log^3({f_q})). The construction process is a series of algorithms, where each is a test for primality.
