An Optimization Method for National Cryptography Algorithm

A Python optimization method is proposed to ad-dress the slow and inefficient encryption speed of third-party libraries (gmssl and pysmx) commonly used in Python to im-plement national security encryption algorithms. This method combines bit operations, memory construction of S-boxes, and other methods to improve the encryption speed of national secu-rity algorithms. Through laboratory comparison and verification, compared to existing third-party national security encryption algorithm libraries, this method can effectively improve the speed of implementing national security encryption algorithms in Python.
