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, high-speed communication channels can be achieved with inexpensive hardware resources. … See more Like in normal counter mode, blocks are numbered sequentially, and then this block number is combined with an initialization vector (IV) and encrypted with a block cipher E, usually AES. The result of this encryption is then 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 GCM is proven secure in the concrete security model. It is secure when it is used with a block cipher that is indistinguishable … See more GCM combines the well-known counter mode of encryption with the new Galois mode of authentication. The key-feature is the ease of parallel … See more GCM mode is used in the IEEE 802.1AE (MACsec) Ethernet security, WPA3-Enterprise Wifi security protocol, IEEE 802.11ad (also … See more According to the authors' statement, GCM is unencumbered by patents.
