As we have seen in the previous chapter, non-malleable zero-knowledge (NMZK) represented a fundamental tool for constructing our 2PC protocol. In this chapter, we show how to design such a NMZK protocol, and how this can be used also in the context of multi-party computation. In particular, we show how to design a multi-party protocol for security realizing the coin-tossing functionality.

摘要

As we have seen in the previous chapter, non-malleable zero-knowledge (NMZK) represented a fundamental tool for constructing our 2PC protocol. In this chapter, we show how to design such a NMZK protocol, and how this can be used also in the context of multi-party computation. In particular, we show how to design a multi-party protocol for security realizing the coin-tossing functionality.
