This article addresses the development of quantum communication methods in the context of emerging quantum computing threats and emphasizes the importance of key reconciliation in quantum communication systems. The study focuses on the CASCADE protocol and the design of a software prototype intended for research and educational purposes. A parallel error-correction algorithm based on the actor model was implemented, improving the efficiency of key reconciliation and reducing the amount of exchanged data. Evaluation of the prototype revealed limitations, including the computational cost of message passing, complexity of error handling, and code redundancy due to iterative development. Experimental results confirmed the correct implementation of the core CASCADE algorithms and informed the design of future improvements. Proposed enhancements include redesigning the system architecture, developing interfaces for exporting intermediate data, defining the communication channel as a separate component, and expanding tools for systematic verification and comparative analysis of blind key-reconciliation methods.
