Section 6. finally, describes the elliptic curve factorization method [20]. It is, at the moment, the undisputed champion among factoring methods for the great majority of numbers.
This paper 19 devoted to the deacnption and analysis of a new algonthm to factor positive mtegers It depends on the use of elliptic curves The new m et b öd α obtained from
For these other methods the running time is basically independent of the size of the prime factors of n, whereas the elliptic curve method is substantially faster if the second
We propose a simple number extractor based on elliptic and hyperelliptic curves over quadratic extensions of finite fields. This extractor outputs, for a given point on a curve,
Also all primes p ≤ 19 occur as the order of a torsion point of some elliptic curve over a number field of degree at most 5.. Table 3.2 also contains the results obtained using the
Given a finite Galois extension of Q, the working hypothesis tells us which conjugacy classes in the Galois group appear infinitely many times as the Frobenius symbol of a
hmit As a piofimte abelian group, the stiucture of TE is äs follows If char /c = 0 then TE^Z®Z, where Z is the projective hmit of the groups Z/Z«, n ^ l, if char k=p>0 and Eis
One may think that this is an exceptional property of K; indeed, it implies unique factorization for elements rather than just for ideals, which is known to fail for infinitely
