Final answer:
The encryption algorithm used in TLS 1.2 with AES GCM is AES GCM itself, combining encryption and authentication for improved security and efficiency.option c.
Step-by-step explanation:
The encryption algorithm used in TLS 1.2 with AES GCM is AES GCM itself. In the options provided, AES GCM stands for Advanced Encryption Standard with Galois/Counter Mode, which is a mode of operation for symmetric key cryptographic block ciphers. It is known for its efficiency and security, providing both encryption and authentication. Unlike AES CBC (Cipher Block Chaining) or AES ECB (Electronic Codebook), which are other modes of operations for AES, AES GCM combines counter mode encryption with a Galois mode of authentication, enabling simultaneous encryption and authentication, leading to a performance increase over traditional modes like CBC.
The encryption algorithm used in TLS 1.2 with AES GCM is AES GCM.
AES GCM stands for Advanced Encryption Standard Galois/Counter Mode. It is widely used in secure communication protocols like TLS to provide both encryption and authentication. AES GCM combines the AES encryption algorithm with the Galois/Counter Mode (GCM) operation to provide confidentiality, integrity, and authenticity of data.
Unlike other modes such as AES CBC, AES ECB, and AES CTR, AES GCM is a mode of operation that provides authenticated encryption, meaning that it not only encrypts the data but also provides a way to check the integrity of the data to detect any tampering.
