Example text

Merten’s theorem (see for example [BS96]) states that n 1 pi = eγ , n→∞ log n p − 1 i i=1 lim where pi is the ith prime number. Thus this probability is asymptotically equal to (eγ log ap)/p log 2. The first two claims easily follow from this observation. 2 Let E be a prime-generating elliptic curve defined over the field Fq . Then the following statements can be made about the distribution of the primes generated by E: (i) The number of primes of the form Ek /E1 less than or equal to x, is approximately (eγ / log q) log log x.

It is unfortunately not known whether or not there exist prime-generating elliptic curves, but some good candidates will be given later. First, the possible values of e for which Ee /E1 can be prime will be narrowed down. 3 Let E be an elliptic curve defined over a finite field Fq . Suppose that Ee /E1 is a prime. Then one of the following statements holds: (i) e is prime, (ii) q = 2 and e ∈ {4, 6, 9}1 , (iii) q = 3 and e = 4. Proof: Suppose that e is not a prime and let f be a non-trivial divisor of e.

Then the Frobenius eigenvalues are given by 1 ± i. Furthermore  e 2 − 2e/2+1 + 1    e   2 − 2(e+1)/2 + 1 Ee = 2e + 1   2e + 2(e+1)/2 + 1    e 2 + 2e/2+1 + 1 if if if if if e≡0 e ≡ 1, 7 e ≡ 2, 6 e ≡ 3, 5 e≡4 (mod (mod (mod (mod (mod 8), 8), 8), 8), 8). Let E be the elliptic curve defined over F3 with Weierstrass equation Y 2 = X 3 −X−1. √ Then the Frobenius eigenvalues are given by (3 ± i 3)/2 and  e 3 − 2 · 3e/2 + 1     3e − 3(e+1)/2 + 1     3e − 3e/2 + 1  Ee = 3e + 1   3e + 3e/2 + 1      3e + 3(e+1)/2 + 1   e 3 + 2 · 3e/2 + 1 if if if if if if if e≡0 e ≡ 1, 11 e ≡ 2, 10 e ≡ 3, 9 e ≡ 4, 8 e ≡ 5, 7 e≡6 (mod (mod (mod (mod (mod (mod (mod 12), 12), 12), 12), 12), 12), 12).
