Bernstein's NFS analyzed by Lenstra and Shamir

kousik writes "The analysis of Bernstein's NFS by Arjen Lenstra, Adi Shamir, Jim Tomlinson, Eran Tromer has been put up on cryptosavvy. Seems interesting it comes from Lenstra and Shamir. Lenstra lead the 1994 factorisation of RSA 129. From the abstract: ... We also propose an improved circuit design based on a new mesh routing algorithm, and show that for factorization of 1024-bit integers the matrix step can, under an optimistic assumption about the matrix size, be completed within a day by a device that costs a few thousand dollars..."
