Abstract

Abstract:

With the continuous development of Internet technology, the circulation and trading of digital assets on Web 3.0 have become an important driver for the effective release of data value. However, in the current digital asset trading process, technical challenges still exist, such as uncontrollable data circulation and ambiguous ownership boundaries, especially in the Web 3.0 environment, which presents key challenges such as controllable embedding and dynamic changes in data rights. This study proposes a three-right separation data rights confirmation scheme for Web 3.0, digital asset trading based on blockchain technology and the chameleon signature algorithm. First, a chameleon proxy signature algorithm is designed on the basis of proxy signature and chameleon signature technology to solve the problem of ownership tags not being embedded within the control of the digital asset owner during the data release process. Second, a data trading protocol is constructed on the basis of blockchain technology to solve the problem of dynamic changes in ownership tags during the data release process and to achieve public verification of data rights. Finally, security and experimental simulation analyses show that the ownership tags of this scheme can safely and reliably confirm the rights of transaction data when they cannot be forged, meeting the actual needs of digital asset trading on Web 3.0.

Key words: Web 3.0, data right confirmation, three-right separation, chameleon signature, data trading

摘要：

随着互联网技术的不断发展，Web 3.0中数字资产的流通交易已成为促进数据价值有效释放的重要驱动。然而，当前数字资产交易过程中仍面临数据流通不可控、权属边界模糊等技术难题，特别是在Web 3.0环境下呈现出数据权属可控嵌入与动态变更等关键挑战。针对上述问题，基于区块链技术和变色龙签名算法，提出一种面向Web 3.0数字资产交易的三权分置确权方案。首先，结合代理签名和变色龙签名技术设计变色龙代理签名算法，解决数据发布过程中权属标签未在数字资产拥有者控制范围内进行嵌入的问题；其次，基于区块链技术构建数据交易协议，解决数据发布过程中权属标签动态变更的问题，实现数据权属的公开验证。实验仿真结果表明，该方案的权属标签在不可伪造的情况下，能安全可靠地实现交易数据确权，满足Web 3.0中数字资产交易的实际需求。
