我们展示了如何实现比特币钱包的双因素身份验证。为此,我们解释了如何在比特币环境中采用 MacKenzie 和 Reiter 的两方签名协议的 ECDSA 改编(Int J Inf Secur 2(3–4):218–239, 2004.doi:10.1007/s10207-004-0041-0),并提出比特币钱包的原型实现,该钱包提供双因素身份验证和验证通过一个单独的通道。由于我们使用智能手机作为第二个身份验证因素,因此我们的解决方案可以与大多数用户已有的硬件一起使用,并且用户体验与现有的网上银行身份验证方法非常相似。
We show how to realize two-factor authentication for a Bitcoin wallet. To do so, we explain how to employ an ECDSA adaption of the two-party signature protocol by MacKenzie and Reiter (Int J Inf Secur 2(3–4):218–239, 2004. doi:10.1007/s10207-004-0041-0) in the context of Bitcoin and present a prototypic implementation of a Bitcoin wallet that offers both: two-factor authentication and verification over a separate channel. Since we use a smart phone as the second authentication factor, our solution can be used with hardware already available to most users and the user experience is quite similar to the existing online banking authentication methods.
