Building a Consensus platform for shared sequencing can power an ecosystem of layer-2
solutions such as rollups which are crucial for scaling blockchains (eg, Ethereum). However …

A sequence of recent works have constructed constant-size quasi-adaptive (QA) NIZK
arguments of membership in linear subspaces of ̂ G^ m, where ̂ G is a group equipped …

For many years, non‐repudiation in data delivery has not been satisfactorily achieved due to
the difficulty of supervising delivery behavior. Existing fair protocols are still not entirely free …

The blockchain space is changing constantly. New chains are being implemented frequently
with different use cases in mind. As more and more types of crypto assets are getting real …

Abstract Atomic Cross-Chain Swap (ACCS) is one important topic in cryptocurrency, where
users can securely and trustlessly exchange assets between two different blockchains …

In this paper, we put forward first adaptively chosen plaintext attack (CPA) secure broadcast
encryption with dealership (BED) scheme in standard model. We achieve adaptive security …

Broadcast encryption with dealership (BED) introduced by Gritti et al.(2015) is a proficient
cryptographic primitive which involves a third party called as a dealer and creates a …

The broadcast encryption with dealership (BED) scheme allows a dealer, instead of a
broadcaster, to manage a recipient. Unlike prior broadcast encryption schemes, BED …

理性交换协议是解决小额支付的有效方法, 但是由于参与者的自利性, 理性交换协议的公平性较
难满足. 对理性交换过程中的集体利益进行形式化定义, 并基于占优策略构建理性参与者模型 …

Broadcast Encryption allows a sender to send a message to more than one receiver. In a
typical broadcast encryption, the broadcaster decides the privileged set as in who all can …
