In <em>Crypto93</em>, Damgård showed that any constant-round protocol in which the verifier sends only independent, random bits and which is zero-knowledge against the <em>honest</em> verifier can be transformed into a protocol (for the same problem) that is zero-knowledge <em>in general</em>. His transformation was based on the interactive hashing technique of Naor, Ostrovsky, Venkatesan and Yung, and thus the resulting protocol had very large round-complexity.

Abstract We present a silent self-stabilizing distributed algorithm computing a maximal $\ p$-star decomposition of the underlying communication network. Under the unfair distributed scheduler, the most general scheduler model, the algorithm converges in at most $12\Delta m + \mathcal{O}(m+n)$ moves, where $m$ is the number of edges, $n$ is the number of nodes and $\Delta $ is the maximum node degree. Regarding the time complexity, we obtain the following results: our algorithm outperforms the previously known best algorithm by a factor of $\Delta $ with respect to the move complexity. While the round complexity for the previous algorithm was unknown, we show a $5\big \lfloor \frac{n}{p+1} \big \rfloor +5$ bound for our algorithm.
