First of all the Ecrypt project is is really outdated. Second you're reading the table wrong. Curve25519 gives you 128 bit of symmetric security, but the curve is 255 bit long. So from your table this compares to 3248 RSA.
Third I'm no fan of such key number tables, it's a bit arbitrary and doesn't really reflect the complexities of modern cryptography.
- mSparks 10y agoso we should just take yours, and a random blogs word for it over a group of eu cryptologists paid by the eu to keep our data safe from the us and russian state hackers. again. no thanks. you want to join all the american idiots listening to such nonesense disinformation and give all your data to the ruskies. be my guest.
- acqq 10y agoThe paper of the designers of ed25519 specifies the design of the curve: the modulo is 2 to the 255th power - 19 (note that it's how the curve got its name), in the table you quote it's equvalent to (roughly) 3000 RSA bits: https://ed25519.cr.yp.to/ed25519-20110926.pdf https://ed25519.cr.yp.to/ed25519-20110926.pdf
