基于LWE的识别方案

LWE-based Identification Schemes

Rosemberg Silva, Antonio Campello, Ricardo Dahab

摘要:

一些来自格的困难问题,如LWE(带错误的学习),特别适合于密码学中的应用,因为可以使用最坏情况到平均情况的约简作为强安全性的证据。在这项工作中,我们展示了两个基于LWE的零知识识别方案的结构,并讨论了它们的性能和安全性。我们还强调了设计选择,使我们的解决方案的理论和实践的兴趣。

英文摘要:

Some hard problems from lattices, like LWE (Learning with Errors), are particularly suitable for application in Cryptography due to the possibility of using worst-case to average-case reductions as evidence of strong security properties. In this work, we show two LWE-based constructions of zero-knowledge identification schemes and discuss their performance and security. We also highlight the design choices that make our solution of both theoretical and practical interest.
