We derive a lower bound on the round complexity of an $m$-bounded concurrent black-box zero-knowledge interactive proof protocol. This is an extension of the result of the Canetti-Kilian-Petrank-Rosen to the case of $m$-bounded concurrency. The resulting bound is $o(\frac{\log m}{\log\log m})$. Considering it together with our previous result on an upper bound $\omega(\log m)$, we can conclude that the asymptotic order almost $\log m$ is optimal. |
