In cryptography, Galois/Counter Mode (GCM) [1] is a 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 …

Galois/Counter Mode (GCM) is a block cipher mode of operation that uses universal hashing over a binary Galois field to provide authenticated encryption. It can be implemented in hardware to achieve high speeds with low cost and low latency. Software implementations can achieve excel lent performance by using table-driven field operations.

2007年11月28日 · This Recommendation specifies the Galois/Counter Mode (GCM), an algorithm for authenticated encryption with associated data, and its specialization, GMAC, for generating a message authentication code (MAC) on data that is not encrypted. GCM and GMAC are modes of operation for an underlying approved... See full abstract

The Galois/Counter Mode (GCM) is an algorithm for authenticated encryption that addresses confidentiality and authenticity at the same time. It is a NIST standard designed to avoid security flaws in authenticated encryption.

Galois/Counter Mode (GCM) is a block cipher mode of operation that uses universal hashing over a binary Galois field to provide authenticated encryption.

2016年6月15日 · This document, The Galois/Counter Mode (GCM) and GMAC Validation System (GCMVS), specifies the procedures for validating implementations of the Galois/Counter Mode (GCM), an algorithm for authenticated encryption with associated data, and its specialization, GMAC, for generating a message authentication code (MAC) on data that is not

2017年1月4日 · Special Publication 800-38D specifies the Galois/Counter Mode (GCM) of the AES algorithm. GCM combines the counter mode for confidentiality with an authentication mechanism that is based on a universal hash function.

The recently introduced Galois/Counter Mode (GCM) of op-eration for block ciphers provides both encryption and message authenti-cation, using universal hashing based on multiplication in a binary finite field. We analyze its security and performance, and show that it is the most efficient mode of operation for high speed packet networks, by using

The GCM mode uses an initialization vector (IV) in its processing. This mode is used for authenticated encryption with associated data. GCM provides confidentiality and authenticity for the encrypted data and authenticity for the additional authenticated data (AAD).

Galois/Counter Mode (GCM) is an encryption mode that combines the counter mode (CTR) of block cipher encryption with the Galois mode of authentication. It's widely used for its efficiency and security, particularly in encrypting and authenticating data in communication protocols like TLS and IPsec.
