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.
* Note: The same AES key, IV and AAD must be used for encryption and * decryption.
They are designed to be easily computable. .

Feb 23, 2015 · Our other preferred TLS 1. Symmetric encryption is very fast as compared to asymmetric encryption and are used in systems such as database system. Our tool makes sure that every Encryption Key in your list will be unique, and will only be added once.
A high- performance unified coprocessor for AES-128 and SM4 encryption is proposed in this paper. Security. Oct 15, 2021 · 7.
8. GCM 要求对每个加密和验证数据块（128 位）在 Galois 字段中进行一次分组密码操作和一次 128 位乘法。 分组密码操作很容易流水线化或并行化；乘法运算很容易流水线化，并且可以通过一些适度的努力进行并行化（通过并行化实际操作，通过 根据原始 NIST 提交.

GCM is constructed from an approved symmetric key block cipher with a block size of 128 bits , such as the Advanced Encryption Standard (AES) algorithm that is specified in Federal Information Processing Standard (FIPS.
Advanced Encryption Standard (AES) is a symmetric encryption algorithm. This document defines the Galois Counter Mode with Secure Short Tags (GCM-SST) Authenticated Encryption with Associated Data (AEAD) algorithm.
The modes include EAX, CCM and GCM mode.
