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 02 '12 at 09:11
  • yes... I havent found solution yet – WhyWhat Oct 05 '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 06 '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"... :( – WhyWhat Oct 07 '12 at 08:49
