WebActually, with RSA as you describe, there is a problem with a very small e: if you use e = 3 and encrypt the very same message m with three distinct public keys, then an attacker can recover m. But that's not really due to using a small e; rather, it is due to not applying a proper padding. Share Improve this answer Follow WebJul 13, 2024 · Viewed 2k times. 1.

Web2.3 Existing Models for Detecting Weak RSA Keys The naive way to detect weak RSA keys is to factor the RSA moduli. However, even with number eld sieve, the fastest known factoring method, it would take thousands of years to factor one million RSA keys [KAF+10].

WebJan 24, 2024 · The common modulus attack is performed on Text-Book RSA when Alice and Bob use the same modulus n with different public modulus. The first observation is that this is dangerous since Alice can learn Bob's private key, v.s. On the other hand, the eavesdropper ( passive attacker) knows the public keys ( n, e 1) and ( n, e 2) and when …
