Secure Quantum Communication: Simulation and Analysis of Quantum Key Distribution Protocols

Quantum computing poses significant threats to conventional cryptographic techniques such as RSA and AES, motivating the need for quantum secure communication methods. Quantum Key Distribution QKD offers information theoretic security based on fundamental quantum principles. This paper presents a...

Quantum CDMA-Based Continuous Variable Quantum Key Distribution Using Chaotic Phase Shifters

We present a quantum code-division multiple-access q-CDMA framework for multiuser continuous-variable quantum key distribution CV-QKD over a shared quantum channel. The proposed architecture employs chaotic phase shifters to encode and decode quantum states, enabling efficient multiplexing and...

CVE-2025-15603

A security vulnerability has been detected in open-webui up to 0.6.16. Affected is an unknown function of the file backend/startwindows.bat of the component JWT Key Handler. Such manipulation of the argument WEBUISECRETKEY leads to insufficiently random values. It is possible to launch the attack...

CVE-2025-15603

Open WebUI up to version 0.6.16 is reported to contain a security issue in the JWT Key Handler, specifically in the file backend/start_windows.bat. Manipulating the WEBUI_SECRET_KEY argument can lead to insufficient randomness in keys, potentially enabling remote exploitation. Multiple connected ...
