Ndapota ndipei pfupiso yechinonzi AES-GCM uye kuti zvii zvainopinda uye zvainobuda.
Context:In cryptography, Galois / Counter Mode (GCM) chinhu muoti kushanda nokuda symmetric-kiyi cryptographic block ciphers iyo zvikuru vakagamuchira nokuda kwayo kuita. GCM throughput rates for state-of-the-art, high-speed communication channels can be achieved with inexpensive hardware resources.  GCM algorithm inopa zvose kuvimbika kwedata (kuvimbika) uye zvakavanzika uye ndeyekirasi yekodhi yakasimbiswa ine data yakabatana (AEAD) nzira. Izvi zvinoreva kuti sezvo chiyamuro zvinotora kiyi K, vamwe plaintext P, uye vamwe chokuita mashoko AD; zvino encrypts ari plaintext vachishandisa kiyi kubudisa ciphertext C, uye computes munhu authentication Tag T kubva ciphertext uye chokuita mashoko (anoramba unencrypted). Mugamuchiri ane zivo yeK, pakugamuchira AD, C uye T, anogona kubvisa ciphertext kuti adzorere plaintext P uye anogona kutarisa tag T kuti ave nechokwadi chokuti kana ciphertext kana data yakabatana haina kubviswa.
AES-GCM inzira yekushanda ye symmetric-key cryptography. Inomirira Galois/Counter Mode uye inonzi authenticated block cipher iyo inopa kuvimbika uye kuvimbika pamusoro pekuvanzika. Inogamuchira sechinhu chinopinda kiyi K, plaintest P uye yakabatana nedata AD, uye inoburitsa sechibudiso ciphertext C uye tag yekusimbisa T.
