WebAbstract: We show that if the private exponent d used in the RSA (Rivest-Shamir-Adleman (1978)) public-key cryptosystem is less than N/sup 0.292/ then the system is insecure. This is the first improvement over an old result of Wiener (1990) showing that when d is less than N/sup 0.25/ the RSA system is insecure.

WebOct 15, 2016 · In RSA: One should use a large enough size n for the public modulus N; that's important because anything that factors N will break the RSA instance using that N, and the resistance of N to factorization tends to grow with n (for constant number of factors of size proportional to n ).
