Paper proposes adaptive primality testing for public-key cryptography
The architecture targets prime generation for RSA, Diffie-Hellman, and ECC, including proofs when prime distributions are biased.
Gutmann cites Fermat checks for RSA keys with close primes
On the eMudhra intermediates thread, he says Let's Encrypt rejects public keys whose primes are too close.
Paper gives DM-RSA-OAEP a formal fault-detection security treatment
IND-CCA2 security is bounded by the weaker RSA-OAEP instance, and detection fails if both moduli share one chip’s faults.
