 Jun 2 comment Which attacks are possible against raw/textbook elliptic curve? Indeed. I'm referring to RSA public key encryption. Jun 2 comment Which attacks are possible against raw/textbook elliptic curve? There are no other EC schemes which i'm missing here? RSA can safely encrypt up to 245 bytes if I remember correctly (exchanging session keys using some defined format for example). EC has no such means of exchanging session keys. If you want that you should use it in a key agreement scheme. Jun 2 asked Which attacks are possible against raw/textbook elliptic curve? Mar 19 comment HMAC tag to verify the key (verification in the reverse direction) $S_0$ and $S_1$ are random, never re-used and hard to compute. So that should not be a problem. Mar 19 asked HMAC tag to verify the key (verification in the reverse direction) Jun 6 comment Why is verification using DSA slower than verification with RSA? @HenrickHellström: Thank you for the response. Jun 6 awarded Commentator Jun 6 comment Why is verification using DSA slower than verification with RSA? A quick follow up, is there a big difference in authentication and verification complexity between RSA with a 1024 modulus and a 2048 modulus?
