Galois/Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (GCMP) is a cryptographic protocol that has become increasingly relevant when developing and deploying software and applications. GCMP combines the Galois/Counter Mode (GCM) encryption algorithm with the Cipher Block Chain...
In the Electronic Code Book (ECB) mode, which is a simple mode of operation with block ciphers, the same plaintext is always encrypted with the key into identical ciphertext. In other words, encryption of the same plaintext with the same key generates the same ciphertext, leaving the messa...
Galois/Counter Mode.InGCM mode, blocks are combined with an IV and encrypted with AES. The result is then XORed with the plaintext to generate the ciphertext. Counter Mode with CBC Message Authentication Code Protocol.CCMPmode is for use with AES. It uses a 128-bit block size and a 128...
Data encryption/decryption ciphers.AES128-GCM, or advanced encryption standard inGalois counter mode(GCM), is ablock cipherthat’s used to encrypt and decrypt the data transmitted in blocks of a pre-determined size. Among other bulk ciphers we can findCHACHA20_and POLY1305,stream ciphersencryptin...
There are also other modes of operation that you can familiarize yourself with as well, such asGalois Counter Mode (GCM)andXEX Tweakable Block Cipher with Ciphertext Stealing (XTS)mode (includingXTS for AES mode). But we’re not going to get into all of those here. ...

WPA3 encryption is an essential element for standard wireless security. It provides enhanced security features for enterprises and individuals alike, such as 256-bit Galois/Counter Mode Protocol (GCMP-256), 256-bit Hashed Message Authentication Mode (HMAC), and 256-bit Broadcast/Multicast Integrity ...
Key protection: The more secure HMAC-SHA-384 algorithm is used to export and confirm keys in the 4-way handshake phase. (HMAC: hash-based message authentication code; SHA: secure hash algorithm) Traffic protection: The more secure Galois-Counter Mode Protocol-256 (GCMP-256) is used to prot...
While the MACsec protocol is not new, today you can use it to secure your Ethernet interfaces in alignment with the latest requirements, better securing the entire system. At the heart of MACsec is the Advanced Encryption Standard-Galois/Counter Mode Cryptography (AES-GCM), the same ...
Cipher Block Chaining (CBC) mode with an Hashed Message Authentication Code (HMAC)-based Message Authentication Code (MAC) with SHA-256 or SHA-384. The other eight use the new authenticated encryption modes defined in TLS 1.2 with AES in Galois Counter Mode (GCM) with SHA-256 or SHA-384....
