....the effectiveness of the proposed method. For example, the proposed method runs 3 or 4 times faster than the original ECM. 3.1 Introduction It is important to find efficient factoring algorithms for evaluating the security of cryptosystems. The ae method [50] p 0 1 method [49] p 1 method [21], continued fraction method [51] quadratic sieve method [45] number field sieve method [34] elliptic curve factoring method [33] 43] etc. have been proposed. These methods have been classified into two types: algorithms depending on prime factors and algorithms depending on composite numbers. ....

....forit ing method [1] This method is widely re#ered to as P 1 method. Factoring the composite number N , P 1 method is very e#ective when P 1 isf)L: P into small primes, where P is af( of the N. In 1975, Guy suggested P 1 method which is a similar algorithm to P 1 method [2]. Since cryptosystem based on the problemof fblemP( the composite number N can be attacked with P 1 and P 1 methods, it is required that P 1 and P 1 should be di#cult to be f : PB into many small primes. The trial division method is well known as an e# cient methodf= generating ....

Maier on gaps between consecutive primes, the exact formulation of Cram er s conjecture has now been called into question, however the conjecture required for [GK86] is unaffected.

....program factor for IBM PC and compatible computers [3] The program factor should be considered primarily as a means of accessing a file of known factors, rather than as a general purpose factorization program. For surveys of factorization algorithms and programs, we refer the reader to [1, 2, 7, 8, 10, 13, 14, 16, 17, 18, 19, 20]. Over the past few years we have systematically extended our list of factors, concentrating on numbers a n Sigma 1 for 13 a 100, n 100, but also considering some larger values of the exponent n for the smaller bases a. The tables are now complete for n 46 and include no composites with ....

.... the scenes of this world wide computing effort (Section 5) and some concluding remarks (Section 6) 2 Predicting the difficulty of factoring r Back in 1976, Richard Guy wrote I shall be surprised if anyone regularly factors numbers of size 10 80 without special form during the present century [8]. In 1977, Rivest estimated in [20] that factoring a 125 digit number which is the product of two 63 digit prime numbers would require at least 40 quadrillion years using the best factoring algorithm known, assuming that a b (modc) could be computed in 1 nanosecond, for 125 digit numbers a, b, ....
