....factor has been found by ECM. Factors of larger numbers are customarily found by trial division [16, 18] 2. The Elliptic Curve Method ECM was invented by H. W. Lenstra, Jr. 23] Various practical refinements were suggested by Brent [1] Montgomery [24, 25] and Suyama [32] We refer to [3, 14, 22, 26, 31] for a description of ECM and some of its implementations. In the following, we assume that ECM is used to find a prime factor p 3 of a composite number N , not a prime power [21, x2.5] The first phase limit for ECM is denoted by B 1 . 1991 Mathematics Subject Classification. 11Y05, 11B83, ....

....p 2 . This algorithm is more ecient than the previously proposed one [5] In Section 4, we will introduce the Duality Law of a pair of reciprocal characteristic sequences. Using this law, we show the property of redundancy in states of characteristic sequences over GF (q) Lenstra and Verheul in [8] have also found this type of redundancy for a special case of characteristic sequences over GF (p 2 ) However the technique used in [8] can not be extended to the general case of the characteristic sequences over either GF (p 2 ) or GF (q) for any arbitrary q. In Section 5, using the linear ....

....suppose that we know ae i for some i 2 f1; n Gamma 1g. If deg ae i = n then set ae i 1 = ae i . If deg ae i n then we need to construct ae i 1 as a primitive element of Q(ae i ; i 1 ) over Q. We determine the minimal polynomial of i 1 , and factor it over Q(ae i ) By the result of [7] this can be done in polynomial time. This determines the degree d = Q(ae i ; i 1 ) Q(ae i ) If d = 1 then we set ae i 1 = ae i . Now suppose that d 1. For t 2 f1; 2; n 2 g we form the minimal polynomials of ae i t i 1 , until we find an element of degree d Delta deg ae i ....

.... overcome by the invention of the (special) number field sieve (SNFS) based on a new idea of Pollard [43, 61] In 1990, Lenstra, Lenstra, Manasse and Pollard, with the assistance of many collaborators and approximately 700 workstations scattered around the world, completely factored F 9 by SNFS [44, 45]. The factorization is F 9 = 2424833 Delta 7455602825647884208337395736200454918783366342657 Delta p 99 : In x8 we show that it would have been possible (though more expensive) to complete the factorization of F 9 by ECM. F 10 was the most wanted number in various lists of composite numbers ....

Lenstra, Jr. 46] in 1985. Practical refinements were suggested by various authors [8, 23, 50, 51, 72] We refer to [45, 52, 62, 71] for a general description of ECM, and to [24, 69] for relevant background. Suppose we attempt to find a factor of a composite number N , which we can assume not to be a perfect power [2] 44, x2.5] Let p be the smallest prime factor of N . In practice it is desirable to remove small factors (up ....
