Factoring polynomials with rational coefficients
TLDR
We present a Polynomial-time algorithm to solve the following problem: given a non-zero polynomial fe Q(X) in one variable with rational coefficients, find the decomposition of f into irreducible factors in Z(X). Expand

The XTR Public Key System
This paper introduces the XTR public key system. XTR is based on a new method to represent elements of a subgroup of a multiplicative group of a finite field. Application of XTR in cryptographicExpand

Selecting Cryptographic Key Sizes
TLDR
We give guidelines for the determination of cryptographic key sizes, based on a set of explicitly formulated hypotheses, combined with existing data points. Expand

Factorization of a 768-Bit RSA Modulus
TLDR
This paper reports on the factorization of the 768-bit RSA-768 by the number field sieve factoring method and discusses some implications for RSA. Expand

Selecting Cryptographic Key Sizes
TLDR
We offer guidelines for the determination of key sizes for symmetric cryptosystems, RSA, and discrete logarithm-based cryptsystems both over finite fields and over groups of elliptic curves. Expand

Hard Equality Constrained Integer Knapsacks
We consider the following integer feasibility problem: Given positive integer numbersa0,a1, ... , a n , with gcd( a1,..., a n ) = 1 anda = ( a1,..., a n ), does there exist a vectorx?Z nExpand

Chosen-Prefix Collisions for MD5 and Colliding X.509 Certificates for Different Identities
TLDR
We present a novel, automated way to find differential paths for MD5 at an approximate expected cost of 250 calls to the compression function. Expand

The Development of the Number Field Sieve
The number field sieve is an algorithm to factor integers of the form $r^e-s$ for small positive $r$ and $s$. The authors present a report on work in progress on this algorithm. They informallyExpand

The number field sieve
TLDR
The number field sieve is an algorithm to factor integers of the form re − s for small positive r and |s| using arithmetic in an algebraic number field. Expand

A random zoo: sloth, unicorn, and trx
TLDR
We show how sloth can be used for uncontestable random number generation (unicorn), and how unicorn is used for a new trustworthy random ellip­ tic curves service. Expand
