WebOct 29, 2024 · Short description: Authenticated encryption mode with resistance against nonce reuse. AES-GCM-SIV is a mode of operation for the Advanced Encryption Standard which provides similar performance to Galois/Counter Mode as well as misuse resistance in the event of the reuse of a cryptographic nonce. The construction is defined in RFC 8452. WebThe algorithm uses a 16-round Feistel network structure similar to its predecessor, CIPHERUNICORN-E, but with significant changes.
