GCM (Galois Counter Mode) is a mode of operation for block ciphers. An AEAD (authenticated encryption with additional data) mode is a type of block cipher mode that simultaneously encrypts the message as well as authenticating it. Additional unencrypted data may also be authenticated.

RFC 5647 - AES Galois Counter Mode for the Secure Shell RFC 5647 AES-GCM for Secure Shell August 2009 3.Applicability Statement Using AES-GCM to provide both confidentiality and data integrity is generally more efficient than using two separate algorithms to provide these security services. 4.Properties of Galois Counter Mode Galois Counter Mode (GCM) is a mode of operation for block ciphers that provides both confidentiality and data integrity. IA Architects Mode on Intel Architecture Processors The mode of operation of AES in the GCM mode is the counter or CTR mode. We describe optimizations that improve performance of counter mode processing by alleviating the critical-path.

Galois/Counter Mode (GCM) is a mode of operation for symmetric block ciphers that's mainly used with AES (AES-GCM). GCM consists of Counter (CTR) Mode encryption followed by a universal hash function, Galois Hashing, for authentication. GMAC is a variation that provides authentication but not encryption.
java - Can PKCS5Padding be in AES/GCM mode? - Stack Overflow GCM is a streaming mode which means that the ciphertext is only as long as the plaintext (not including authentication tag). GCM doesn't require a padding. Carry-Less Multiplication Instruction, Usage for the GCM Mode

Next Generation Cryptography - Cisco Configure the negotiated TLS cipher suites to include AES-128 or AES-256 GCM as the encryption algorithms and SHA-256 or SHA-384 for the hashes. The negotiated cipher suites should include: WITH_AES_128_GCM_SHA256 or WITH_AES_256_GCM_SHA384; WITH_AES_256_GCM_SHA256 or WITH_AES_256_GCM_SHA384 Alternatives are: WITH_AES_128_CBC_SHA256 Why would I ever use AES-256-CBC if AES-256-GCM is more GCM = CBC + Authentication. Nope, GCM = CTR + Authentication. But in general you are right; CBC is an older mode that was invented back in the dark ages cryptographically speaking (no later than the 1970s), and is now disfavored because of the lack of built-in authentication and all the trouble that's been caused by padding oracles.
