报告题目: Blockchain-Based Anonymous Reporting Scheme with Anonymous Rewarding 


报 告 人:王化群 教授

邀 请 人: 付安民


报告摘要:For the first time, we propose the novel concept of blockchain-based anonymous reporting scheme with anonymous rewarding (for short, BB2AR). Our BB2AR scheme solves the open problem: how to realize the anonymous reporting and the anonymous rewarding simultaneously? First, we formalize the system model, definition and security model of BB2AR. Second, we propose a concrete BB2AR scheme based on the elliptic curve public key cryptography (for short, ECC). Our formal proof shows that our BB2AR scheme satisfies the anonymous reporting and the anonymous rewarding simultaneously. Finally, we analyze its efficiency and give its prototype implementation. From the comparison, our BB2AR scheme is more efficient and practical.
