Semi-honest MPC ⇒ Semi-honest 2PC

Fully-black-box reduction · standard model · folklore · security loss: none

Statement

A family of protocols that securely computes, for every $n$, every $n$-party functionality against semi-honest adversaries corrupting up to $n-1$ parties (semi-honest security) contains, for $n=2$, a protocol that securely computes every two-party functionality against a semi-honest adversary corrupting either party (semi-honest 2PC) — folklore.
