Introduction to Cryptography

  • In section 5.2 (RSA), the statement "But m is relatively prime to n (because n = pq ...)" is not necesarily true. We could pick all m < p and q, making it true, but this is not necessary. Knowing that m is relatively prime to p and q is good enough to prove that m^{ed} = m (mod n) even if m is not an element of Z_n^*..
