# Is there any Elliptic Curve algorithm equivalent to RSA's asymmetric encryption?

I've been searching but I cant find anything about this... only EC Diffie-Hellman with symmetric cryptography, which is exactly what I do not want :(

Imagine this:

• generate a random private key, k
• then calculate a "public key" with ECC, d=kG

The algorithm I'm looking for is this: any message cyphered with the public key will "only" be decyphered by the owner of the private key.

Does this exists? Has anything like this been developed yet?

Have you looked at Elliptic Curve Cryptography? –  JSchlather Oct 2 '12 at 9:11
yes... I havent found solution yet –  Funenga Oct 5 '12 at 19:14
I'm a little confused. Did you look at the section on ECDSA which is a public key algorithm based on ECC? –  JSchlather Oct 6 '12 at 20:16
yes i have... In section "Key and signature size comparison to DSA" its written: "Suppose Alice wants to send a signed message to Bob.". Also in "Signature verification algorithm" step 2 has: "e=HASH(m)" That m is the plain text message. This means that ECDSA is only used to check the message integrity. As far as the algorithm is concerned, the trasnmission can be: "plain_text_message+signature"... :( –  Funenga Oct 7 '12 at 8:49
