(UDP), we use AES-256 GCM mode to encrypt these compressed data streams. Additionally, for video, voice, and content share encrypted with AES, once it’s encrypted, it remains encrypted as it passes through Zoom’s meeting servers until it reaches another Zoom Client or a Zoom Connector, which helps translate the data to another protocol. SRTP GCM and GMAC authenticated encryption algorithms 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. Thus, GCM is a mode of operation of the AES algorithm. GCM provides assurance of the confidentiality of data using a variation of the Counter mode of operation for encryption. Using Intel® AES-NI to Significantly Improve IPSec AES-GCM block cipher algorithm and mode combination. Advanced Encryption Standard (AES) Advanced Encryption Standard (AES) is a set of block ciphers taken from the Rijndael [2] symmetric key block cipher specification. The standard defines a How would you explain 'TLS 1.2 ECDHE RSA with AES 256 GCM
GCM mode requires that the IV is a nonce, i.e., the IV must be unique for each execution of the mode under the given key. The steps for GCM encryption are: The hash subkey for the GHASH function is generated by applying the block cipher to the “zero" block.

AES¶ AES (Advanced Encryption Standard) is a symmetric block cipher standardized by NIST. It has a fixed data block size of 16 bytes. Its keys can be 128, 192, or 256 bits long. AES is very fast and secure, and it is the de facto standard for symmetric encryption. As an example, encryption can be done as follows:
