Authentication weaknesses in GCM - NIST
GCM combines the well-known counter mode of encryption with the new Galois mode of authentication. The key-feature is the ease of parallel-computation of the Galois field multiplication used for authentication. This feature permits higher throughput than encryption algorithms, like CBC, which use … See more In cryptography, Galois/Counter Mode (GCM) is a AEAD mode of operation for symmetric-key cryptographic block ciphers which is widely adopted for its performance. GCM throughput rates for state-of-the-art, … See more Like in normal counter mode, blocks are numbered sequentially, and then this block number is combined with an initialization vector (IV) … See more GCM requires one block cipher operation and one 128-bit multiplication in the Galois field per each block (128 bit) of encrypted and authenticated … See more • Authenticated encryption • Block cipher mode of operation • AES-GCM-SIV See more GCM mode is used in the IEEE 802.1AE (MACsec) Ethernet security, WPA3-Enterprise Wifi security protocol, IEEE 802.11ad (also dubbed WiGig), ANSI (INCITS See more According to the authors' statement, GCM is unencumbered by patents. See more GCM is proven secure in the concrete security model. It is secure when it is used with a block cipher that is indistinguishable from a random permutation; however, security depends … See more WebGHASH: universal hash over GF(2^128) used by AES-GCM for message authentication (i.e. GMAC).. Implementation Notes. The implementation of GHASH found in this crate internally uses the polyval crate, which provides a similar universal hash function used by AES-GCM-SIV (RFC 8452).
