AI Technical Summary
Among existing quantum key distribution technologies, the confidentiality enhancement algorithms have low performance, high hardware resource consumption, slow operation speed, and insufficient pseudo-randomness of the final key.
A key security enhancement method based on two-dimensional cellular automata is adopted. By setting the number of rows, columns and key compression ratio of the cellular automata, the negotiated key is converted into a submatrix. Bitwise operations and XOR operations are performed using the iterative structure of the cellular automata to generate a pseudo-random sequence with good randomness, and finally the final key is formed.
It improves the speed of security enhancement and the pseudo-randomness of the final key, realizes efficient utilization of hardware resources and real-time key output, and enhances the performance of the security enhancement algorithm.
