AES-GCM-SIV uses the authentication tag (created with Polyval over the plaintext and the associated data) as a nonce for AES-CTR to encrypt the plaintext. This is the trick behind SIV: the nonce used to encrypt in the AEAD is generated from the plaintext itself, which makes it highly unlikely that two different plaintexts will end up being encrypted under the same nonce. AES¶. AES (Advanced Encryption Standard) is a symmetric block cipher standardized by NIST.It has a fixed data block size of 16 bytes.

The plaintext recovered is then used along with the associated data to validate the authentication tag. Both tags need to be compared (in constant-time) before releasing the plaintext to the application. For each block in CTR mode a new unpredictable keystream block is generated based on the initial vector (IV, sometimes called "nonce") + the current counter (01, 02, 03,) + the secret encryption key and the input block is merged by XOR with the current keystream block to produce the output block. Simple chosen-plaintext attack on AES-CTR given NONCE and IV re-use for multiple ciphertexts.
