We present a new design principle for building a batch processing protocol for interactive proofs. First, a generic method to achieve batch processing is proposed when dealing with an NP-relation with certain homomorphicity. It is shown that the method preserves zero-knowledgeness and knowledge-soundness. Second, for some NP-relation that has no such homomorphicity, we illustrate that the relation can be decomposed into a homomorphic relation(hence we have a batch process) and another NP-relation that is proven using an efficient protocol. Such a decomposition provides an advantage in terms of efficiency.
