GCM uses a block cipher with block size 128 bits (commonly AES-128) operated in counter mode for encryption, and uses arithmetic in the Galois field GF(2 128) to compute the authentication tag; hence the name. Galois Message Authentication Code (GMAC) is an authentication-only variant of the GCM which can form an incremental message ...
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.
[2] Suite B's components were: Advanced Encryption Standard (AES) with key sizes of 128 and 256 bits. For traffic flow, AES should be used with either the Counter Mode (CTR) for low bandwidth traffic or the Galois/Counter Mode (GCM) mode of operation for high bandwidth traffic (see Block cipher modes of operation) – symmetric encryption
Yes, Galois/Counter Mode needs a block cipher, because you cannot run a stream cipher in counter mode, by definition. You can combine a stream cipher with a MAC based on polynomial multiplication in general, in fact, Google in particular does this a lot , but it will not be reasonable to call it GCM.
AES-GCM-SIV is a mode of operation for the Advanced Encryption Standard which provides similar (but slightly worse [1]) 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. [2]
Counter mode with CBC-MAC (CCM) Galois/Counter Mode (GCM) Cipher Block Chaining (CBC) with HMAC-Secure Hash Algorithm; XTS-HMAC-Secure Hash Algorithm; The P1619.2 Standard for Wide-Block Encryption for Shared Storage Media has proposed algorithms including: Extended Codebook (XCB) Encrypt Mix Encrypt V2 (EME2)
In Sophie Germain Counter Mode, it was proposed to use the arithmetic in the finite field of order equal to the safe prime 2 128 + 12451, to counter weaknesses in Galois/Counter Mode using the binary finite field GF(2 128). However, SGCM has been shown to be vulnerable to many of the same cryptographic attacks as GCM. [26]
A default cipher suite of GCM-AES-128 (Galois/Counter Mode of Advanced Encryption Standard cipher with 128-bit key) GCM-AES-256 using a 256 bit key was added to the standard 5 years later. Security tag inside each frame in addition to EtherType includes: association number within the channel
