There seemed to be no reason why everyone couldn’t just use the same prime, and, in fact, many applications tend to use standardized or hard-coded primes.
Then, if the prime number is standardized or hard-coded, why they just not use it? Why we need to break it?
- macns 11y agoIt shouldn't be nor standardized nor hard-coded because someone with the funds (e.g. NSA) would need to break the encryption using this 'standardized' number only once. If everyone used a random very large prime (spec suggests so) then NSA would have to break with every prime number possible which currently is not possible
