EC ElGamal multiplicatively Homomorphic

pn flag

Can we make EC ElGamal have multiplicative homomorphic property?

If you can find a homomorphism $f$ that maps from the domain multiplicative group to EC group with point addition, allowing efficient calculation both ways, you can. Do you know of such thing?

No, because you can't multiply one group element with another group element.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
