WebIn this paper we propose an algorithm of factoring any integer N which has k different prime factors with the same bit-length, when \((\frac{1}{k+2}+\frac{\epsilon}{k(k-1)})\log N\) high-order bits of each prime factor are given. For a fixed ε, the running time of our algorithm is heuristic polynomial in (logN).Our factoring algorithm is based on a new lattice-based … WebThese attacks assume that we know some part of one of the factors of N. For example, if we know the most significant bits of p; more precisely, let a match p on all but the bottom 86 …

"WebSymmetric key block ciphers process fixed-size blocks simultaneously using the same key to encrypt the data. The block size of a cipher refers to the number of bits that are processed together. The original DES algorithm specified the use of 56-bit keys. As computing advanced, this proved ineffective protection against certain attacks. " - Known high bits factor attack
