Devices that are unable to generate high-quality keys are exposed to multiple vulnerabilities. In this work, we present an Entropy-as-a-Service (EaaS) architecture to address this problem. The proposed solution creates secure keys and sends them to a mobile application using a Quantum Random Number Generator (QRNG). Futhermore, our solution provides anonymity to the users who request a key while ensuring that the EaaS provider can still apply access control policies. Keys are sent via a quantum channel and received by the mobile application via NFC to ensure security. A certificate is generated with the key to authenticate the user in the application services. This certificate creates an identity separate from his real identity.engAtribución 4.0http://creativecommons.org/licenses/by/4.0/Quantum Random Number Generator (QRNG)NFC technologyEntropy-asa-Service (EaaS)Implementation of a User Anonymity Application Using a Privacy-Preserving Entropy-as-a-Service with Quantum Securityconference outputopen access
