WebDec 26, 2007 · (a * b) mod p == 1. Which makes sense, as (in "real speak") a is the inverse of b if a*b == 1, i.e., a = 1/b. To find a, given b and p, requires the use of the "Greatest Common Divisor" (GCD) which returns the largest integer less than (or equal to) a (or) and b that divides a and b evenly.. If this integer is 1, then a and b are relative prime, since only 1 can … WebWiener’s Low Decryption Exponent Attack. Wiener described a polynomial-time algorithm for cracking a typical RSA cryptosystem in 1990, i.e., if p and q are the same size and e < n. Suppose the secret exponent d has no more than one-quarter the number of bits as the modulus n. We also know that there is an integer k for which ed − kφ (N)=1.
