The development of quantum technologies is progressing faster than expected. While quantum computing poses a threat to currently used cryptography, there are also new solutions for resistance towards such attacks including quantum and post-quantum security. The current focus by information security agencies is the transition to post-quantum cryptography. NIST and the European Commission have published their related roadmaps. Our digital infrastructures heavily rely on cryptographic security and the transition timelines are tight. Cryptography is the very security backbone of authorization protocols. At the same time, authorization is a critical digital process for infrastructure security. Such assets are expected to be transitioned by the end of 2030 according to the EU roadmap. The project Quant-ID researched quantum entropy and post-quantum cryptography in OAuth and OIDC on the network and application layer in order to enable a smoother transition. We implemented a multi-component demonstrator, including an authorization server on an IBM VPC instance, relying rarties and a quantum random number generator. In this talk, we will present our main results and challenges in enabling a smooth transition to quantum-safe OAuth and OIDC.
