Theoretical Cryptanalysis of the Klimov-Shamir Number Generator TF-1
The internal state of the Klimov–Shamir number generator TF-1 consists of four words of size w bits each, whereas its intended strength is 22w. We exploit an asymmetry in its out...

Deterministic Polynomial-Time Equivalence of Computing the RSA Secret Key and Factoring
Abstract. We address one of the most fundamental problems concerning the RSA cryptosystem: does the knowledge of the RSA public and secret key-pair (e, d) yield the factorization o...
