    摘要: This article describes how after the concept of anonymous credential systems was introduced in 1985, a number of similar systems have been proposed. However, these systems use zero-knowledge protocols to authenticate users, resulting in inefficient authentication during the stage of proving credential possession. To overcome this drawback, this article presents a signature scheme that uses partially blind signatures and chameleon hash functions such that both the prover and verifier achieve efficient authentication. In addition to providing a computational cost comparison table showing that the proposed signature scheme achieves a more efficient credential possession proving compared to other schemes, concrete security proofs are provided under a random oracle model to demonstrate that the proposed scheme satisfies the properties of anonymous credentials.
