Abstract

Post-quantum public cryptosystems introduced so far do not define a scalable public key infrastructure for the quantum era. We demonstrate here a public certification system based on Lizama's non-invertible key exchange protocol which can be used to implement a secure, scalable, interoperable and efficient public key infrastructure (PKI). We show functionality of certificates across different certification domains. Finally, we discuss a method that enables non-invertible certificates to exhibit perfect forward secrecy (PFS).

摘要

迄今为止推出的后量子时代公共密码系统并未为量子时代定义一个可扩展的公钥基础设施。我们在此展示一种基于利萨马不可逆密钥交换协议的公共认证系统，该系统可用于实现一个安全、可扩展、可互操作且高效的公钥基础设施（PKI）。我们展示了证书在不同认证域中的功能。最后，我们讨论了一种使不可逆证书能够展现完美前向保密性（PFS）的方法。
