SM4GCM
SM4GCM is an authenticated encryption algorithm that combines the SM4 block cipher with the Galois/Counter Mode (GCM). It provides both confidentiality and data integrity by encrypting plaintext and generating an authentication tag for associated data and ciphertext.
SM4 is a 128-bit block cipher with a 128-bit key, standardized in China for governmental and commercial
The security properties of SM4GCM rely on the standard assumptions of GCM: a unique IV (nonce) for
Applications and implementation of SM4GCM appear in Chinese cryptographic ecosystems, where SM4 and its authenticated modes
