Authentication is of paramount significance to cybersecurity. However, most of conventional authentication schemes are implemented in a centralized mode, in which potential problems that could arise include single-point failure, the exposure of personal information, and the risk of identity theft. Additionally, static single-factor authentication schemes are unsuitable for dynamic environments like mobile applications. In order to tackle these difficulties, we propose a blockchain-based authentication scheme with an adaptive multi-factor authentication strategy. Our scheme features a blockchain-based authentication framework that prevents unauthorized information alteration and system corruption. Additionally, we design an adaptive multi-factor authentication strategy model to ensure trustworthy multi-factor authentication in dynamic scenarios. Last, we construct a Raft-based consensus model to select an authoritative leading node for rapid authentication. The security analysis demonstrates the effectiveness of the proposed scheme in effectively countering various forms of cyberattacks targeted at authentication systems, and experiments demonstrate its superior effectiveness and efficiency compared to existing studies.

具有自适应多因素身份验证策略的基于区块链的身份验证方案

身份验证对于网络安全至关重要。然而，传统的认证方案大多以集中式方式实现，可能出现的潜在问题包括单点故障、个人信息暴露以及身份盗用的风险。此外，静态单因素身份验证方案不适合移动应用程序等动态环境。为了解决这些困难，我们提出了一种基于区块链的身份验证方案，具有自适应多因素身份验证策略。我们的方案具有基于区块链的身份验证框架，可以防止未经授权的信息更改和系统损坏。此外，我们设计了自适应多因素身份验证策略模型，以确保动态场景下值得信赖的多因素身份验证。最后，我们构建了一个基于Raft的共识模型来选择权威的主导节点进行快速认证。安全分析证明了该方案在有效对抗针对身份验证系统的各种形式的网络攻击方面的有效性，并且实验证明了与现有研究相比其优越的有效性和效率。
